Laine Stump 91195b4321 qemu: leave rerror policy at default when enospace is requested
commit 12062ab set rerror=ignore when error_policy="enospace" was
selected (since the rerror option in qemu doesn't accept "enospc", as
the werror option does).

After that patch was already pushed, Paolo Bonzini noticed it and
commented that leaving rerror at the default ("report") would be a
better choice. This patch corrects the problem - if error_policy =
"enospace" is given, rerror is left off the qemu commandline,
effectively setting it to "report". For other values, rerror is still
set to match werror.

Additionally, the parsing of error_policy was changed to no longer
erroneously allow "default" as a choice - as with most other
attributes, if you want the default setting, just don't specify an
error_policy.

Finally, two ommissions in the first patch were corrected - a
long-dormant qemuxml2argv test for enospace was enabled, and fixed to
pass, and the argv2xml parser in qemu_command.c was updated to
recognize the different spelling on the qemu commandline.

Oskari Saarenmaa f887334dcf Add unsafe cache mode support for disk driver
QEMU 0.13 introduced cache=unsafe for -drive, this patch exposes
it in the libvirt layer.

  * Introduced a new QEMU capability flag ($prefix_CACHE_UNSAFE),
    as even if $prefix_CACHE_V2 is set, we can't know if unsafe
    is supported.

  * Improved the reliability of qemu cache type detection.

Jiri Denemark f84aedad09 qemu: Fix shutdown regression with buggy qemu
The commit that prevents disk corruption on domain shutdown
(96fc478417) causes regression with QEMU
0.14.* and 0.15.* because of a regression bug in QEMU that was fixed
only recently in QEMU git. The affected versions of QEMU do not quit on
SIGTERM if started with -no-shutdown, which we use to implement fake
reboot. Since -no-shutdown tells QEMU not to quit automatically on guest
shutdown, domains started using the affected QEMU cannot be shutdown
properly and stay in a paused state.

This patch disables fake reboot feature on such QEMU by not using
-no-shutdown, which makes shutdown work as expected. However,
virDomainReboot will not work in this case and it will report "Requested
operation is not valid: Reboot is not supported with this QEMU binary".

Marc-André Lureau fdd14a9d05 qemu: Don't append 0 at usb id, so that it is compatible with legacy -usb
QEMU uses USB bus name "usb.0" when using the legacy -usb argument.
If we want to allow USB devices to specify their addresses with legacy
-usb, we should either in case of legacy bus name drop the 0 from the
address bus, or just drop the 0 from device id. This patch does the
later.

Another solution would be to permit addressing on non-legacy USB
controllers only.

Laine Stump 73c0a148af qemu: support event_idx parameter for virtio disk and net devices
In some versions of qemu, both virtio-blk-pci and virtio-net-pci
devices can have an event_idx setting that determines some details of
event processing. When it is enabled, it "reduces the number of
interrupts and exits for the guest". qemu will automatically enable
this feature when it is available, but there may be cases where this
new feature could actually make performance worse (NB: no such case
has been found so far).

As a safety switch in case such a situation is encountered in the
field, this patch adds a new attribute "event_idx" to the <driver>
element of both disk and interface devices. event_idx can be set to
"on" (to force event_idx on in case qemu has it disabled by default)
or "off" (for force event_idx off). In the case that event_idx support
isn't present in qemu, the attribute is ignored (this on the advice of
the qemu developer).

   "don't mess with this!"

Daniel P. Berrange 42f43592be Support reboots with the QEMU driver
For controlled shutdown we issue a 'system_powerdown' command
to the QEMU monitor. This triggers an ACPI event which (most)
guest OS wire up to a controlled shutdown. There is no equiv
ACPI event to trigger a controlled reboot. This patch attempts
to fake a reboot.

 - In qemuDomainObjPrivatePtr we have a bool fakeReboot
   flag.
 - The virDomainReboot method sets this flag and then
   triggers a normal 'system_powerdown'.
 - The QEMU process is started with '-no-shutdown'
   so that the guest CPUs pause when it powers off the
   guest
 - When we receive the 'POWEROFF' event from QEMU JSON
   monitor if fakeReboot is not set we invoke the
   qemuProcessKill command and shutdown continues
   normally
 - If fakeReboot was set, we spawn a background thread
   which issues 'system_reset' to perform a warm reboot
   of the guest hardware. Then it issues 'cont' to
   start the CPUs again

  we have JSON support

Michal Privoznik 017abcbb1a qemu: domain I/O asynchronous handling
For virtio disks and interfaces, qemu allows users to enable or disable
ioeventfd feature. This means, qemu can execute domain code, while
another thread waits for I/O event. Basically, in some cases it is win,
in some loss. This feature is available via 'ioeventfd' attribute in disk
and interface <driver> element. It accepts 'on' and 'off'. Leaving this
attribute out defaults to hypervisor decision.

Jiri Denemark c3068d4d23 qemu: Translate boot config into bootindex if possible
Prefer bootindex=N option for -device over the old way -boot ORDER
possibly accompanied with boot=on option for -drive. This gives us full
control over which device will actually be used for booting guest OS.
Moreover, if qemu doesn't support boot=on, this is the only way to boot
of certain disks in some configurations (such as virtio disks when used
together IDE disks) without transforming domain XML to use per device
boot elements.

Eric Blake d51023d4c2 qemu: fix restoring a compressed save image
Latent bug introduced in commit 2d6a581960 (Aug 2009), but not exposed
until commit 1859939a (Jan 2011).  Basically, when virExec creates a
pipe, it always marks libvirt's side as cloexec.  If libvirt then
wants to hand that pipe to another child process, things work great if
the fd is dup2()'d onto stdin or stdout (as with stdin: or exec:
migration), but if the pipe is instead used as-is (such as with fd:
migration) then qemu sees EBADF because the fd was closed at exec().

This is a minimal fix for the problem at hand; it is slightly racy,
but no more racy than the rest of libvirt fd handling, including the
case of uncompressed save images.  A more invasive fix, but ultimately
safer at avoiding leaking unintended fds, would be to _always and
atomically_ open all fds as cloexec in libvirt (thanks to primitives
like open(O_CLOEXEC), pipe2(), accept4(), ...), then teach virExec to
clear that bit for all fds explicitly marked to be handed to the child
only after forking.

* src/qemu/qemu_command.c (qemuBuildCommandLine): Clear cloexec
flag.
* tests/qemuxml2argvtest.c (testCompareXMLToArgvFiles): Tweak test.

Osier Yang 82dfc6f38e qemu: Support vram for video of qxl type
For qemu names the primary vga as "qxl-vga":

  1) if vram is specified for 2nd qxl device:

    -vga qxl -global qxl-vga.vram_size=$SIZE \
    -device qxl,id=video1,vram_size=$SIZE,...

  2) if vram is not specified for 2nd qxl device, (use the default
     set by global):

    -vga qxl -global qxl-vga.vram_size=$SIZE \
    -device qxl,id=video1,...

For qemu names all qxl devices as "qxl":

  1) if vram is specified for 2nd qxl device:

    -vga qxl -global qxl.vram_size=$SIZE \
    -device qxl,id=video1,vram_size=$SIZE ...

  2) if vram is not specified for 2nd qxl device:

    -vga qxl -global qxl-vga.vram_size=$SIZE \
    -device qxl,id=video1,...

"-global" is the only way to define vram_size for the primary qxl
device, regardless of how qemu names it, (It's not good a good
way, as original idea of "-global" is to set a global default for
a driver property, but to specify vram for first qxl device, we
have to use it).

For other qxl devices, as they are represented by "-device", could
specify it directly and seperately for each, and it overrides the
default set by "-global" if specified.

v1 - v2:
  * modify "virDomainVideoDefaultRAM" so that it returns 16M as the
    default vram_size for qxl device.

  * vram_size * 1024 (qemu accepts bytes for vram_size).

  * apply default vram_size for qxl device for which vram_size is
    not specified.

  * modify "graphics-spice" tests (more sensiable vram_size)

  * Add an argument of virDomainDefPtr type for qemuBuildVideoDevStr,
    to use virDomainVideoDefaultRAM in qemuBuildVideoDevStr).

v2 - v3:
  * Modify default video memory size for qxl device from 16M to 24M

  * Update codes to be consistent with changes on qemu_capabilities.*

Laine Stump e9bd5c0e24 Add txmode attribute to interface XML for virtio backend
This is in response to:

   https://bugzilla.redhat.com/show_bug.cgi?id=629662

Explanation

qemu's virtio-net-pci driver allows setting the algorithm used for tx
packets to either "bh" or "timer". This is done by adding ",tx=bh" or
",tx=timer" to the "-device virtio-net-pci" commandline option.

'bh' stands for 'bottom half'; when this is set, packet tx is all done
in an iothread in the bottom half of the driver. (In libvirt, this
option is called the more descriptive "iothread".)

'timer' means that tx work is done in qemu, and if there is more tx
data than can be sent at the present time, a timer is set before qemu
moves on to do other things; when the timer fires, another attempt is
made to send more data. (libvirt retains the name "timer" for this
option.)

The resulting difference, according to the qemu developer who added
the option is:

    bh makes tx more asynchronous and reduces latency, but potentially
    causes more processor bandwidth contention since the cpu doing the
    tx isn't necessarily the cpu where the guest generated the
    packets.

Solution

This patch provides a libvirt domain xml knob to change the option on
the qemu commandline, by adding a new attribute "txmode" to the
<driver> element that can be placed inside any <interface> element in
a domain definition. It's use would be something like this:

    <interface ...>
      ...
      <model type='virtio'/>
      <driver txmode='iothread'/>
      ...
    </interface>

I chose to put this setting as an attribute to <driver> rather than as
a sub-element to <tune> because it is specific to the virtio-net
driver, not something that is generally usable by all network drivers.
(note that this is the same placement as the "driver name=..."
attribute used to choose kernel vs. userland backend for the
virtio-net driver.)

Actually adding the tx=xxx option to the qemu commandline is only done
if the version of qemu being used advertises it in the output of

    qemu -device virtio-net-pci,?

If a particular txmode is requested in the XML, and the option isn't
listed in that help output, an UNSUPPORTED_CONFIG error is logged, and
the domain fails to start.

Wen Congyang 6bf4788e86 qemu: fix attach-interface regression
QEMUD_CMD_FLAG_PCI_MULTIBUS should be set in the function
qemuCapsExtractVersionInfo()

The flag QEMUD_CMD_FLAG_PCI_MULTIBUS is used in the function
qemuBuildDeviceAddressStr(). All callers get qemuCmdFlags
by the function qemuCapsExtractVersionInfo() except that
testCompareXMLToArgvFiles() in qemuxml2argvtest.c.

So we should set QEMUD_CMD_FLAG_PCI_MULTIBUS in the function
qemuCapsExtractVersionInfo() instead of qemuBuildCommandLine()
because the function qemuBuildCommandLine() does not be called
when we attach a pci device.

tests: set QEMUD_CMD_FLAG_PCI_MULTIBUS in testCompareXMLToArgvFiles()

set QEMUD_CMD_FLAG_PCI_MULTIBUS before calling qemuBuildCommandLine()
as the flags is not set by qemuCapsExtractVersionInfo().

Daniel P. Berrange be87a1236e spicevmc: support new qemu chardev
Inspired by https://bugzilla.redhat.com/show_bug.cgi?id=615757

Add a new character device backend for virtio serial channels that
activates the QEMU spice agent on the main channel using the vdagent
spicevmc connection.  The <target> must be type='virtio', and supports
an optional name that specifies how the guest will see the channel
(for now, name must be com.redhat.spice.0).

<channel type='spicevmc'>
  <target type='virtio'/>
  <address type='virtio-serial' controller='1' bus='0' port='3'/>

either the default (threads) or native (linux aio) which in the latter
case can result in better performance.

Cole Robinson 6cabc0b0d0 qemu: sound: Support intel 'ich6' model
In QEMU, the card itself is a PCI device, but it requires a codec
(either -device hda-output or -device hda-duplex) to actually output
sound. Specifying <sound model='ich6'/> gives us -device intel-hda
-device hda-duplex I think it's important that a simple <sound model='ich6'/>
sets up a useful codec, to have consistent behavior with all other sound cards.

This is basically Dan's proposal of

    <sound model='ich6'>
        <codec type='output' slot='0'/>
        <codec type='duplex' slot='3'/>
    </sound>

without the codec bits implemented.

The important thing is to keep a consistent API here, we don't want some
<sound> devs require tweaking codecs but not others. Steps I see to
accomplishing this:

    - every <sound> device has a <codec type='default'/> (unless codecs are
        manually specified)
    - <codec type='none'/> is required to specify 'no codecs'
    - new audio settings like mic=on|off could then be exposed in
        <sound> or <codec> in a consistent manner for all sound models

v2:
    Use model='ich6'

v3:
    Use feature detection, from eblake
    Set codec id, bus, and cad values

v4:
    intel-hda isn't supported if -device isn't available

v5:

Cole Robinson 1d9c0a08d9 qemu: Allow serving VNC over a unix domain socket
QEMU supports serving VNC over a unix domain socket rather than traditional
TCP host/port. This is specified with:

<graphics type='vnc' socket='/foo/bar/baz'/>

This provides better security access control than VNC listening on
127.0.0.1, but will cause issues with tools that rely on the lax security
(virt-manager in fedora runs as regular user by default, and wouldn't be
able to access a socket owned by 'qemu' or 'root').

Also not currently supported by any clients, though I have patches for
virt-manager, and virt-viewer should be simple to update.

v2:

Eric Blake 1859939a74 qemu: use -incoming fd:n to avoid qemu holding fd indefinitely
https://bugzilla.redhat.com/show_bug.cgi?id=620363

When using -incoming stdio or -incoming exec:, qemu keeps the
stdin fd open long after the migration is complete.  Not to
mention that exec:cat is horribly inefficient, by doubling the
I/O and going through a popen interface in qemu.

The new -incoming fd: of qemu 0.12.0 closes the fd after using
it, and allows us to bypass an intermediary cat process for
less I/O.

Jiri Denemark 9237e9558a tests: Support for faking emulator in qemuxml2argv
This patch allows for using custom scripts instead of /usr/bin/qemu
emulator in domain XML. To do so, one would specify relative path to the
custom script in <emulator/>. The path needs to be relative to
qemuxml2argvdata directory and it will be transparently made absolute in
runtime. The expected command line needs to contain the exact relative
path as was used in domain XML.

The problem is RelaxNG schema for domain XML only allows for absolute
path within <emulator/>. To workaround it, an extra '/' must be added at
the beginning of the path. That is, instead of "./qemu.sh" or
"../emulator/qemu.sh" one would use "/./qemu.sh" or
"/../emulator/qemu.sh". The extra slash is removed before further
processing. I don't like this workaround, it's very ugly but it's the
best option I was able to come up with. Relaxing domain XML schema is
not an option IMO.

Daniel P. Berrange 38536d6f7f Annotate some virConnectPtr as mandatory non-null
Use the ATTRIBUTE_NONNULL annotation to mark some virConnectPtr
args as mandatory non-null so the compiler can warn of mistakes

* src/conf/domain_event.h: All virConnectPtr args must be non-null
* src/qemu/qemu_conf.h: qemudBuildCommandLine and

Daniel P. Berrange 910b019f93 Convert qemu command line flags to 64-bit int
The QEMU flags are commonly stored as a signed or unsigned int,
allowing only 31 flags. This limit is rather close, so to aid
future patches, change it to a 64-bit int

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h, src/qemu/qemu_driver.c,
  tests/qemuargv2xmltest.c, tests/qemuhelptest.c, tests/qemuxml2argvtest.c:
  Use 'unsigned long long' for QEMU flags

Daniel P. Berrange 65842bf669 Remove virConnectPtr from all domain XML parsing/formatting APIs 2010-02-10 11:49:23 +00:00
Daniel P. Berrange 49a0f6cd99 Remove use of -netdev arg with QEMU
The QEMU 0.12.x tree has the -netdev command line argument, but not
corresponding monitor command. We can't enable the former, without
the latter since it will break hotplug/unplug.

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Disable -netdev usage
  until 0.13 at earliest
* tests/qemuxml2argvtest.c: Add test for -netdev syntax
* tests/qemuxml2argvdata/qemuxml2argv-net-virtio-netdev.args,

2010-02-02 16:31:47 +00:00
Daniel P. Berrange 9258ec0a2e Rewrite way QEMU PCI addresses are allocated
The current QEMU code allocates PCI addresses incrementally starting
at 4. This is not satisfactory because the user may have given some
addresses in their XML config, which need to be skipped over when
allocating addresses to remaining devices.

It is thus neccessary to maintain a list of already allocated PCI
addresses and then only allocate ones that remain unused. This is
also required for domain device hotplug to work properly later.

* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add APIs for creating
  list of existing PCI addresses, and allocating new addresses.
  Refactor address assignment to use this code
* src/qemu/qemu_driver.c: Pull PCI address assignment up into the
  qemuStartVMDaemon() method, as a prelude to moving it into the
  'define' method. Update list of allocated addresses when connecting
  to a running VM at daemon startup.
* tests/qemuxml2argvtest.c, tests/qemuargv2xmltest.c,
  tests/qemuxml2xmltest.c: Remove USB product test since all
  passthrough is done based on address
* tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-product.args,
  tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-product.xml: Kil
  unused data files
2010-02-02 16:31:47 +00:00
Matthias Bolte 1671b64702 Unset copied environment variables in qemuxml2argvtest
The test expected all environment variables copied in qemudBuildCommandLine
to have known values. So all of them have to be either set to a known value
or be unset. SDL_VIDEODRIVER and QEMU_AUDIO_DRV are not handled at all but
should be handled. Unset both, otherwise the test will fail if they are set
in the testing environment.

* src/qemu/qemu_conf.c: add a comment about copied environment variables
  and qemuxml2argvtest
* tests/qemuxml2argvtest.c: unset SDL_VIDEODRIVER and QEMU_AUDIO_DRV
2010-01-20 23:22:15 +01:00
Daniel P. Berrange febc591683 Pass -vga none if no video card specified
QEMU always configures a VGA card. If no video card is included in
the libvirt XML, it is neccessary to explicitly turn off the default
using -vga none

* src/qemu/qemu_conf.c: Pass -vga none if no video card is configured
* tests/qemuargv2xmltest.c, tests/qemuxml2argvtest.c: Test for
  handling -vga none.
* tests/qemuxml2argvdata/qemuxml2argv-nographics-vga.args,

2010-01-18 13:55:57 +00:00
Daniel P. Berrange 16658da4e7 Convert PCI device assignment over to -device
The old syntax is

  -pcidevice host=BUS:SLOT:FUNCTION

The new syntax is

  -device pci-assign,host=BUS:SLOT:FUNCTION,addr=<PCI SLOT>,id=host0
2010-01-18 13:55:56 +00:00
Daniel P. Berrange 42ce352c13 Convert USB hostdevices over to -device
The old syntax was

   -usbdevice host:PRODUCT:VENDOR

Or

   -usbdevice host:BUS.DEV

The new syntax is

   -device usb-host,product=PRODUCT,vendor=VENDOR

Or

   -device usb-host,hostbus=BUS,hostaddr=DEV
2010-01-18 13:55:56 +00:00
Daniel P. Berrange 73370e9868 Convert USB disks over to -device
The previous syntax was severely limited in its options

  -usbdevice disk:/home/berrange/output.img

The new syntax is the same as for other disk types

  -drive file=/home/berrange/output.img,if=none,id=usb-1,index=1
  -device usb-storage,drive=usb-1

Again, the index= arg is wrong here, and will be removed in a
later merge
2010-01-18 13:55:56 +00:00
Daniel P. Berrange 1dd6f855c3 Convert NICs over to use -device & -netdev where possible
The current syntax uses a pair of args

   -net nic,macaddr=52:54:00:56:6c:55,vlan=3,model=pcnet,name=pcnet.0
   -net user,vlan=3,name=user.0

The new syntax does not  need the vlan craziness anymore, and
so has a simplified pair of args

   -netdev user,id=user.0
   -device pcnet,netdev=user.0,id=pcnet.0,mac=52:54:00:56:6c:55,addr=<PCI SLOT>
2010-01-18 13:55:56 +00:00
Daniel P. Berrange 4886cba76a Convert audio devices over to -device syntax
The current syntax for audio devices is a horrible multiplexed
arg

    -soundhw sb16,pcspk,ac97

The new syntax is

    -device sb16,id=sound0

or

    -device AC97,id=sound1,addr=<PCI SLOT>

NB, pcspk still uses the old -soundhw syntax
2010-01-18 13:55:56 +00:00
Daniel P. Berrange 38a22fbfaa Convert watchdog to -device
The current syntax for watchdogs is

    -watchdog i6300esb

The new syntax will now be

    -device i6300esb,id=watchdogNN,addr=<PCI-SLOT>
2010-01-18 13:55:56 +00:00
Daniel P. Berrange 7b2f8cdd7c Convert character devices over to use -device
The current character device syntax uses either

  -serial tty,path=/dev/ttyS2

Or

  -chardev tty,id=serial0,path=/dev/ttyS2 -serial chardev:serial0

With the new -device support, we now prefer

  -chardev file,id=serial0,path=/tmp/serial.log -device isa-serial,chardev=serial0

This patch changes the existing -chardev syntax to use this new
scheme, and fallbacks to the old plain -serial syntax for old
QEMU.

The monitor device changes to

  -chardev socket,id=monitor,path=/tmp/test-monitor,server,nowait -mon chardev=monitor

In addition, this patch adds --nodefaults, which kills off the
default serial, parallel, vga and nic devices. THis avoids the
need for us to explicitly turn each off
2010-01-18 13:55:56 +00:00
Matthew Booth a8eb010ea2 Make QEMU driver use -chardev everywhere if available

Daniel P. Berrange b81a7ece97 Fix handling of Xen(ner) detection
Latest upstream QEMU can be built with Xen support, which introduces
a -xen-domid argument. This was  mistakenly detected as -domid due
to old Xenner support. Adapt to cope with both syntax. Also only
set domid if the virt type is xen, or the guest type is xen

* src/qemu_conf.c, src/qemu_conf.h: Detect new -xen-domid flag in
  preference to -domid.

Chris Lalancette 654c5714bf The new generic domain re-factor introduced a small regression into the drive
handling code.  In particular, if you had a section of XML like:

    <disk type='file' device='cdrom'>
      <target dev='hdc' bus='ide'/>
      <readonly/>
    </disk>

This used to work with older libvirt, but now fails.  This is because we are
actually passing the literal string (null) to the qemu command-line, which qemu
barfs on.  This patch fixes it up by making it blank, which allows qemu to
continue on it's merry way.

Jim Meyering 49230350fa Use a variable name as sizeof argument, not a type name.
Given code like: T *var = calloc (n, sizeof (T));
Convert to this: T *var = calloc (n, sizeof (*var));
This first-cut change adjusts all malloc, calloc, and
realloc statements.

The only binary differences are in remote_internal.c
(due to the bug fix) and in xmlrpc.c (due to factorization).

        Removed a clashing redefinition of VERSION symbol.
        All limits (PATH_MAX etc) now done in src/internal.h, so we
        don't need to include those headers in other files.
