[libvirt] [PATCH] qemuBuildVideoCommandLine: Don't access def->videos without check
by Michal Privoznik
This function can be called over a domain definition that has no
video configured. The
tests/qemuxml2argvdata/qemuxml2argv-minimal.xml file could serve
as an example. Problem is, before the check that domain has some
or none video configured, def->videos is dereferenced causing a
segmentation fault in case there's none video configured.

[libvirt] Enhancement: Random Clock Offset
by bancfc＠openmailbox.org
For better system anonymity (to decouple VM OS timestamps leaked in
traffic from host ones) a feature can be added to the clock offset
variable to select randomly from a specified range of seconds from
instead of a fixed number of seconds. That way a guest's clock can vary
unpredictably from the host's and confuse correlation by network
adversaries.
Full Disclosure: I am from the Tor centric Whonix Project - whonix.org
and this would be a very useful feature for us.

[libvirt] [PATCH REPOST 0/9] Reorganize qemu_command.c in smaller piles
by John Ferlan
Rather than hope for a review of 25 patches or creating some remote
place to place a branch - I'll repost the original:
http://www.redhat.com/archives/libvir-list/2016-February/msg00975.html
in smaller chunks. No differences in these patches other than a rebase
to top of tree a short while ago (commit id 'cf091094a'). There were also
no conflicts from changes since initial posting.

[libvirt] any better way to treat device-detach timeout ?
by Zhangbo (Oscar)
Hi,all:
I find that we remove devices only after DEVICE_DELETED event.(patch:3fbf78bd).
And it treats TIMEOUT as success. The detailed codes are shown as below:
rc = qemuDomainWaitForDeviceRemoval(vm);
if (rc == 0 || rc == 1)
ret = qemuDomainRemoveDiskDevice(driver, vm, detach);
else
ret = 0;
Here comes the problem:
If
1. We pass flags=3(VIR_DOMAIN_AFFECT_LIVE|VIR_DOMAIN_AFFECT_CONFIG) to virDomainDetachDeviceFlags,
2. It timed out to receive DEVICE_DELETED event, virDomainDetachDeviceFlags api will return 0(succeed).
Please be aware that: vm->newdef(persistent) removes the device while vm->def(transient) keeps it untouched.
3. Then we try to attach the same device with flag 3, because it differs in newDef and def, the API virDomainDetachDeviceFlags() returns ERROR.
Consequent attach/detach jobs all fail after then.
So, shall we make it return FAIL when it fails in qemuDomainWaitForDeviceRemoval()? Or just remove the device in def after we get the DEVICE_DELETED event?
Any ideas, thanks!

[libvirt] [libvirt-glib v2 0/9] gconfig: Add hostdev support
by Christophe Fergeau
Hey,
While reviewing Zeeshan's libvirt-gconfig hostdev series, I fixed up a few
things, and added a few additional helpers/getters in order to simplify the
code/make the test case more complete.
This series contains this new code. The changes I made to Zeeshan's initial
patches are in separate fixup! commits to make reviewing them easier (for you Zeeshan ;).
I expect these to be squashed in the main commits before being pushed.
Zeeshan's commits are unchanged from v1.
