Eric Blake 4cc2b6d676 virsh: document attach-disk better
http://bugzilla.redhat.com/601143, part 1 - document existing
behavior.  Ever since Mar 2010 (commit ced154cb), the use of
'attach-disk' or 'attach-device' to change cdrom/floppy media has been
documented but deprecated, but the replacement to use 'update-device'
was not documented.

* tools/virsh.c (cmdAttachInterface, cmdAttachDisk): Fix bad error
message.
* tools/virsh.pod (attach-device, attach-disk): Refer to
update-device for cdrom and floppy behavior.
(update-device): Add documentation.

 --backing-vol-format <format-of-backing-vol>

  virsh # vol-create-as guest_images_lvm snapvol1 5G --backing-vol \

Additionally, the virsh man page update fixes incorrect snapshot
parameters that were included in my prior bulk volume command patch.

Justin Clift b221973a11 Add --source-format argument to virsh pool-define-as and pool-create-as
When creating pools from dedicated disks, the existing pool-define-as
and pool-create-as commands are a bit non-optimal.

Ideally, a person would be able to specify all of the required options
directly on the command line instead of having to edit the XML.

At the moment, there is no way to specify the format type (ie gpt) so it
gets included in the XML the pool is constructed with.

Please find attached a simple (tested) patch to add an optional
"--source-format 'type'" to virsh.  This is patched against current git
master and will apply cleanly.

Also created a Red Hat BZ ticket for this (#597790) for tracking.

Justin Clift e5f31f461f Trivial virsh.pod additions --all for "list" command and similar
This is just a trivial patch to virsh.pod (from git master). It adds the
following pieces to the virsh man page:

  + Shows the --inactive and --all optional parameters for the list
    command.

    Closes Bugzilla #575512, reported by Renich Bon Ciric
    https://bugzilla.redhat.com/show_bug.cgi?id=575512

  + Corrects the existing description of the list command, to now say
    that only running domains are listed if no domains are specified.

    The man page up until this point has said all domains are listed if
    no domains are specified, which is incorrect.

  + Adds the "shut off" state to the list of states for the list
    command.

  + Adds a missing =back around line 755, that pod2man was complaining
    was missing.

Eric Blake 6e5b5bbc0a build: fix up some compiler flags
Matthias noted that the line:
virt_aa_helper_LDFLAGS = $(WARN_CFLAGS)
looks inconsistent, so I did an audit.

Currently, the set of compiler warning flags passed to gcc as $CC are
equally permitted as the set of linker flags passed to gcc as $LD, so
there was no problem with that usage.  But if we ever get in a
situation where $CC and $LD treat particular flags differently, using
the right variable form will make it easier.

In the process, I spotted a couple of typos that were omitting useful
flags, as well as specifying a -l under the wrong variable.

* acinclude.m4 (LIBVIRT_COMPILE_WARNINGS): Define WARN_LDFLAGS as
an alias for WARN_CFLAGS.
* tools/Makefile.am (virsh_LDFLAGS): Use more canonical spelling.
* proxy/Makefile.am (libvirt_proxy_LDFLAGS): Likewise. Move
library...
(libvirt_proxy_LDADD): ...here.

spelling of WARN_LDFLAGS.

Kenneth Nagin b0a3f8b6c5 qemu: live migration with non-shared storage for kvm
Support for live migration between hosts that do not share storage was
added to qemu-kvm release 0.12.1.
It supports two flags:
-b migration without shared storage with full disk copy
-i migration without shared storage with incremental copy (same base image
shared between source and destination).

I tested the live migration without shared storage (both flags) for native
and p2p with and without tunnelling.  I also verified that the fix doesn't
affect normal migration with shared storage.

Laine Stump 2b50cae54e Fix memory leaks in cmdInterfaceEdit and cmdNWFilterEdit.
This applies a fix to thos functions similar to that made to cmdEdit
in 270895063d, thus fnixing a memory
leak - if tmp is unlinked and NULLed early in the function, the memory
used by tmp is never freed. Since we will always unlink tmp prior to
freeing its memory at the end of the function, just remove the earlier
code and let cleanup: do the cleanup.

Dustin Kirkland c179a0f63c Fix virt-pki-validate's determination of CN
Ubuntu's gntls package generates an Issuer line that looks like this:
        Issuer: C=US,ST=NY,L=Rochester,O=example.com,CN=example.com CA,EMAIL=hostmaster@example.com

While Red Hat's looks like this
Issuer: CN=Red Hat Emerging Technologies

Note the leading whitespace, and the additional fields in the former.

This patch updates the regular expression to:
 * trim leading characters before "Issuer:"
 * trim anything between Issuer: and CN=
 * trim anything after the next ,

I've tested this against the certool output of both RH and Ubuntu
generated certs.

 2) fix a bashism, == should be = in the case where /bin/sh is a symlink

variable to the autoconf @SYSCONFDIR@ value, and use $SYSCONFDIR
everywhere

Chris Lalancette 23b1e5c0b0 Better error reporting in virsh.
When hitting failures in virsh, a common idiom is
to jump to a cleanup label, free some resources, and
then return a FALSE error code to vshCommandRun.
In theory, vshCommandRun is then supposed to print
out the last error.  The problem is that many of
the cleanup paths have library calls to free resources,
and all of those library calls clear out the last error.
This is leading to situations where no error is being
reported at all.

This patch remedies the situation somewhat by
printing out the errors inside the command methods
themselves when we know it will go through a cleanup
path that will lose the error.

Eric Blake f3661756c1 virsh: support VISUAL, and allow metacharacters in EDITOR
Common Unix practice is to prefer VISUAL over EDITOR, particularly if
the editor of choice spawns a new window.  Thus, it is also common to
see settings like EDITOR='emacs -nw', with the expectation that the
shell will parse this as an argument to 'emacs' and not try to invoke
a file containing a space.

If a user puts junk in EDITOR, they deserve what they get (much more
than virsh will misbehave); furthermore, sudo scrubs EDITOR by
default.  So the blind use of metacharacters in EDITOR should not be
considered too much of a security issue.

* tools/virsh.c (editFile): Prefer VISUAL over EDITOR.  Don't
reject shell metacharacters in EDITOR.

Chris Lalancette 3ebbc241a1 Fix crash in virsh after bogus command
If you ran virsh in interactive mode and ran a command
that virsh could not parse, it would then SEGV
on subsequent commands.  The problem is that we are
freeing the vshCmd structure in the syntaxError label
at the end of vshCommandParse, but forgetting to
set ctl->cmd to NULL.  This means that on the next command,
we would try to free the same structure again, leading
to badness.

* tools/virsh.c: Make sure to set ctl->cmd to NULL after
  freeing it in vshCommandParse()

Define a new command 'dommemstats' to report domain memory statistics.  The
output format is inspired by 'domblkstat' and 'domifstat' and consists of
tag/value pairs, one per line.  The command can complete successfully and
print no output if virDomainMemoryStats is supported by the driver, but not
the guest operating system.

Sample output:
swap_in 0
swap_out 0
major_fault 54
minor_fault 58259
unused 487680
available 502472

All stats referring to a quantity of memory (eg. all above except major and

Chris Lalancette 2d8d9b100b Finer grained migration control
Normally, when you migrate a domain from host A to host B,
the domain on host A remains defined but shutoff and the domain
on host B remains running but is a "transient".  Add a new
flag to virDomainMigrate() to allow the original domain to be
undefined on source host A, and a new flag to virDomainMigrate() to
allow the new domain to be persisted on the destination host B.

Daniel P. Berrange fae0da5c13 Support a new peer-to-peer migration mode & public API
Introduces several new public API options for migration

 - VIR_MIGRATE_PEER2PEER: With this flag the client only
   invokes the virDomainMigratePerform method, expecting
   the source host driver to do whatever is required to
   complete the entire migration process.
 - VIR_MIGRATE_TUNNELLED: With this flag the actual data
   for migration will be tunnelled over the libvirtd RPC
   channel. This requires that VIR_MIGRATE_PEER2PEER is
   also set.
 - virDomainMigrateToURI: This is variant of the existing
   virDomainMigrate method which does not require any
   virConnectPtr for the destination host. Given suitable
   driver support, this allows for all the same modes as
   virDomainMigrate()

The URI for VIR_MIGRATE_PEER2PEER must be a valid libvirt
URI. For non-p2p migration a hypervisor specific migration
URI is used.

virDomainMigrateToURI without a PEER2PEER flag is only
support for Xen currently, and it involves XenD talking
directly to XenD, no libvirtd involved at all.

* include/libvirt/libvirt.h.in: Add VIR_MIGRATE_PEER2PEER
  flag for migration
