[libvirt] Adding timestamps for all emulator output
by Andrey Korolyov
Hello,
I think it would be useful if libvirt will be able to prefix all
messages from emulator pipes with the date stamping, for example I am
trying to catch very rare and non-fatal race with
virtio-serial-bus: Guest failure in adding device virtio-serial0.0
which is specific to the Windows guests on qemu-kvm. I have supporting
infrastructure which can tell me exact times for every action upon
this VM, but as bug is not frequent, the continuous monitoring looks
like an overkill for a desired goal - find a correlation between
emulator event and message from stderr. Patching emulator itself is
barely an option, as it is ugly, requires refresh of the running code
via loopback migration and completely non-universal, as every
hypervisor should be modified seperately.
I`d highly appreciate positive consideration for such functionality
addition or can write a patch shortly, if needed. Thanks!

[libvirt] [PATCH] util: do not take it as wrong if no PortData is found while getting migrateData
by Zhang Bo
The function virNetDevOpenvswitchGetMigrateData() uses the cmd ovs-vsctl to
get portdata. If no portdata is available, rather than failure in running
the cmd, we think we should just print a warning message here, rather than
taking it as wrong, because PortData is just optional for an ovs interface.
If we take it as wrong anyway, in function qemuMigrationBakeCookie() it will
terminate in the middle, and cookies such as NBD would not be baked, further
more errors would happen, such as nbd ports get overflowed, etc.
Thus, we add an if branch in virNetDevOpenvswitchGetMigrateData() to just warn
if portdata is unavailable.

the problem with nicindexes, it began complaining about calling the

pointed out some real problems with this that are fixed by these two
patches (which will be pushed *before* the nicindex fix patch).

[libvirt] Entering freeze for libvirt-1.2.13
by Daniel Veillard
As suggested yesterday, and hearing no opposition, I have just tagged
Redlease Candidate 1 for libvirt-1.2.13 in git and signed tarballs and
rpms for it available at the usual place:
ftp://libvirt.org/libvirt/
Based on my own but minimal testing this seems to work, but obviously
please give it a try so we can squash bugs and portability issues in
time.
A candidate release 2 on Thursday and a final 1.2.13 release next
Monday is the schedule assumeing no major issue is found,
so please give it a test !
Thanks,
Daniel
