I plan to implement it in a month.
It will be fine if you are ready to develop the feature.

Well, here is the patch, that fixes that behaviour.
P.S. Are someone going to implement

...
<source bridge="...">

[libvirt] [PATCH] Some virsh(1) man page fixes
by Mark McLoughlin
Hi,
Just looking at virsh(1), I noticed a reference to xm that should have
referred to virsh.
Found some other things as I fixed:
- Explanation of run states was after the bit about the freecell
command
- State codes like 'r' for running aren't displayed with virsh
- Reference to "xm pause" instead of "virsh suspend"
- "virsh create" explanation confusing and references "xm create";
fixed it up to what I think was the original intention
- Some of the command sections were over-indented
- References to xmdomain.cfg
- Make "see also" reference virt-install, virt-top, virt-mem and
virt-df manpages rather than xmdomain.cfg and xentop
Cheers,
Mark.

[libvirt] [PATCH] Sanitize qemu monitor reads
by Cole Robinson
Reading from the qemu monitor pulls in a whole bunch of
useless control characters. For example, sending the
command 'somecomm' to the monitor returns:
somecomm
unknown command: 'somecomm'
(qemu)
Which is 36 characters, however we end up reading over 200.
The amount we read actually grows quadratically as a function
of the command length. This prevents us from reporting monitor
output to the user (incase some command fails) and seriously
diminishes the value of the domain logfiles.
The attached patch tries to sanitize this a bit. After reading
all the output, we search for the first occurrence of the full
command string. If found, we search from there for the first
newline (which marks the beginning of the monitor response).
If these are found, we only return the command, and everything
after the newline. If only the command is found, we just drop
everything before it.
I've tested this on f9 and f8, there didn't seem to be any
problems. I think this should be pretty future proof as
well, so we hopefully won't be throwing out anything
valuable.
Thanks,
Cole

[libvirt] [PATCH] Log virRun command output, return with error
by Cole Robinson
The attached patch adds some extra logging to the
virRun command. The full argv is now logged with
DEBUG, as well as the commands stdout and stderr
(if anything is found).
Also, if the command returns an error, we raise
the stderr content with the reported error msg.
This will significantly help with debugging certain
issues, particularly with the storage driver which
makes heavy use of virRun.
Thanks,
Cole

[libvirt] [PATCH] fix spec file when building without qemu
by Daniel Veillard
While trying to build libvirt 0.4.6 for Fedora, I got an error
when building on ppc64 which is the only architecture where qemu
support is disabled. Files which were conditional to qemu were
installed nonetheless in the build root:
Checking for unpackaged file(s): /usr/lib/rpm/check-files
/builddir/build/BUILDROOT/libvirt-0.4.6-1.fc10.ppc64
error: Installed (but unpackaged) file(s) found:
/etc/libvirt/qemu/networks/autostart/default.xml
/etc/libvirt/qemu/networks/default.xml
/usr/share/augeas/lenses/libvirtd_qemu.aug
/usr/share/augeas/lenses/tests/test_libvirtd_qemu.aug
The following patch doesn't look ideal but allows to fix the problem.
