[libvirt] [PATCH 0/1] Support domain restore from root-squash NFS
by Laine Stump
Most of the explanation is in the commit message with the patch
proper. When reveiwing please take pains to point out any places where
I may not be diligent enough cleaning up loose ends, especially in
terms of assuring that the child process always terminates properly no
matter what happens.
The (unrelated) race condition in qemudDomainRestore() remains - I
solved it locally by putting a sleep(10) just before
qemuMonitorStartCPUs(), but it needs something with a bit higher
comfort factor ;-)

[libvirt] [PATCH] Add TCK script for host USB device hotplug/unplug
by Daniel P. Berrange
This adds support for testing host USB device hotplug/unplug in
libvirt drivers. This currently fails in all known libvirt
drivers :-) The QEMU driver only support the hotplug action,
not unplug, hence the failure.
Since the TCK can't assume there are any host USB devices that
can be safely messed around with, the person running the test
suite must first list one or more devices in the config file.
If no devices are listed, the test will automatically skip
all parts, rather than failing.
* conf/default.cfg: Config entry to specify USB devices that the
TCK can mess around with
* lib/Sys/Virt/TCK.pm: API for getting a host USB device from
the config
* scripts/domain/240-usb-host-hotplug.t: Test case for USB
device hotplug/unplug.

[libvirt] Update on 0.7.7 release schedule
by Daniel Veillard
As you can have noticed we still have patches queued up and not yet
pushed, plus added a new interface yesterday. I'm travelling all of this
week, so my bandwidth is limited. Plus February is a short month and
we skipped a bit for 0.7.6, so time to validate and push patches has
been shorter than usual.
So I suggest to still push patches today and tomorrow for features,
and start the freeze on thusday evening, and delaying the release to mid
of next week.
But still try to keep the expected cycle for 0.7.8 with a freeze on
March 19 and a release on the 26 :-)
Hope this doesn't disrupt other people schedules !
