qemu allows the user to choose what io storage api should be used,
either the default (threads) or native (linux aio) which in the latter
case can result in better performance.
Based on a patch originally by Matthias Dahl.
Red Hat Bugzilla #591703

This supports the '-vga qxl' parameter in upstream QEMU/KVM
which has SPICE support added. This isn't particularly useful
until you get the next patch for -spice support. Also note that
while the libvirt XML supports multiple video devices, this
patch only supports a single one. A later patch can add support
for 2nd, 3rd, etc PCI devices for QXL
* src/qemu/qemu_conf.h: Flag for QXL support
* src/qemu/qemu_conf.c: Probe for '-vga qxl' support and implement it
* tests/qemuxml2argvtest.c, tests/qemuxml2xmltest.c,
tests/qemuxml2argvdata/qemuxml2argv-graphics-spice.args,
tests/qemuxml2argvdata/qemuxml2argv-graphics-spice.xml: Test
case for generating spice args with RHEL6 kvm
* src/qemu/qemu_conf.c (qemuParseCommandLineSmp): Distinguish
between vcpus and maxvcpus, for new enough qemu.
* tests/qemuargv2xmltest.c (mymain): Add new test.
* tests/qemuxml2argvtest.c (mymain): Likewise.
* tests/qemuxml2xmltest.c (mymain): Likewise.
* tests/qemuxml2argvdata/qemuxml2argv-smp.args: New file.
Adding parsing code for memory tunables in the domain xml file
also change the internal define structures used for domain memory
informations
Adds a new specific test
Add tests for auto memballon, implicit IDE, SCSI, virtio channel
controllers, and console/serial back compat.
Additionally, an explicit qemuxml2argvtest for scsi disks is added.

Add a new element to the <os> block:
<bootmenu enable="yes|no"/>
Which maps to -boot,menu=on|off on the QEMU command line.
I decided to use an explicit 'enable' attribute rather than just make the
bootmenu element boolean. This allows us to treat lack of a bootmenu element
as 'use hypervisor default'.
* virStorageEncryptionFormat is called from both
virDomainDiskDefFormat and virStorageVolTargetDefFormat. The proper
indentation in the generated XML depends on the caller. My earlier
patch to fix the incorrect indentation for the domain XML broke the
indentation for the storage XML. This patch adopts Laine's
suggestion of requring the caller of virStorageEncryptionFormat to
provide an unsigned int with the number of spaces the output should
be indented. The patch modifies both callers to provide the
additional argument.
* Add a regression test for the domain XML
* src/conf/domain_conf.c src/conf/storage_conf.c
src/conf/storage_encryption_conf.c src/conf/storage_encryption_conf.h:
change the indentation code
* tests/qemuxml2xmltest.c
tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.args
tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.xml: add a regression test
Add support for virtio-serial by defining a new 'virtio' channel target type
and a virtio-serial controller. Allows the following to be specified in a
domain:
<controller type='virtio-serial' index='0' ports='16' vectors='4'/>
<channel type='pty'>
<target type='virtio' name='org.linux-kvm.port.0'/>
<address type='virtio-serial' controller='0' bus='0'/>
</channel>
* docs/schemas/domain.rng: Add virtio-serial controller and virtio
channel type.
* src/conf/domain_conf.[ch]: Domain parsing/serialization for
virtio-serial controller and virtio channel.
* tests/qemuxml2xmltest.c
tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: add domain xml
parsing test
* src/libvirt_private.syms src/qemu/qemu_conf.c:
virDomainDefAddDiskControllers() renamed to
virDomainDefAddImplicitControllers()
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
When parsing the <disk> element specification, if no <address>
is provided for the disk, then automatically assign one based on
the <target dev='sdXX'/> device name. This provides for backwards
compatability with existing applications using libvirt, while also
allowing new apps to have complete fine grained control.
* src/conf/domain_conf.h, src/conf/domain_conf.c,
src/libvirt_private.syms: Add virDomainDiskDefAssignAddress()
for assigning a controller/bus/unit address based on disk target
* src/qemu/qemu_conf.c: Call virDomainDiskDefAssignAddress() after
generating XML from ARGV
* tests/qemuxml2argvdata/*.xml: Add in drive address information
to all XML files
Introduce a new type="dir" mode for <disks> that allows use of
QEMU's virtual FAT block device driver. eg
<disk type='dir' device='floppy'>
<source dir='/tmp/test'/>
<target dev='fda' bus='fdc'/>
<readonly/>
</disk>
gets turned into
-drive file=fat:floppy:/tmp/test,if=floppy,index=0
Only read-only disks are supported with virtual FAT mode

tests/qemuxml2argvtest.c: Test QEMU vitual FAT driver
* src/qemu/qemu_conf.c: Support generating fat:/some/dir type
disk args
* src/security/security_selinux.c: Temporarily skip labelling
of directory based disks
allows the following to be specified in a domain:
<channel type='pipe'>
<source path='/tmp/guestfwd'/>
<target type='guestfwd' address='10.0.2.1' port='4600'/>
</channel>
* proxy/Makefile.am: add network.c as dep of domain_conf.c
* docs/schemas/domain.rng src/conf/domain_conf.[ch]: extend the domain
schemas and the parsing/serialization side for the new construct
