[libvirt] can't get right capabilities
by Li Zhang
Hi,
I am trying to use x86 machine to create VMs.
But one error occurs.
[root@mcd kvm-test]# virsh create test.xml
error: Failed to create domain from test.xml
error: unknown OS type hvm
My xml file is as the following:
<domain type='kvm'>
<name>test</name>
<memory>524288</memory>
<memorybacking>
<hugepages/>
</memorybacking>
<vcpu>2</vcpu>

<serial type='pty'>
<target port='0'/>
</serial>
<console type='pty'>
<target type='serial' port='0'/>
</console>
<memballoon model="none"/>
</devices>
</domain>
I check kvm module, it is available.
[root@mcd kvm-test]# lsmod |grep kvm
kvm_intel 119308 4
kvm 344876 1 kvm_intel
But I tried the capabilities, it is not right.
There is no guest capabilities.

</capabilities>
This problem occurs some times.
When I tried to find this problem, it didn't occur.
Now it occurs again. It's a little strange.
Is there anything I miss?

[libvirt] [PATCH v3 0/2] Make virsh *edit more bearable
by Michal Privoznik
If there's an error in XML, all changes made by user are lost.
Users (read /me) tends to get angry with this. Allow them to
get back and re-edit.
diff to v2:
-some bugfixes (like flawn in snapshot edit)
-new EDIT_FREE to avoid leaks
(Both suggested by Eric)
diff to v1:
-Eric's review suggestions included
Michal Privoznik (2):
virsh: Switch from generated cmd*Edit commands to nongenerated
virsh: Allow users to reedit rejected XML

[libvirt] [PATCH] qemu: Move -name arg to be the 1st so it's visible in "ps x"
by Marti Raudsepp
Hi list,
Currently, monitoring QEMU virtual machines with standard Unix
sysadmin tools is harder than it has to be. The QEMU command line is
often miles long and mostly redundant, it's hard to tell which process
is which.
This patch reorders the QEMU -name argument to be the first, so it's
immediately visible in "ps x", htop and "atop -c" output.
Patch attached and also available from my github fork (master @
git://github.com/intgr/libvirt.git)
Regards,
Marti

[libvirt] [PATCH] qemu: fix netdev alias name assignment wrt type='hostdev'
by Laine Stump
This patch resolves:
https://bugzilla.redhat.com/show_bug.cgi?id=827519
The problem is that an interface with type='hostdev' will have an
alias of the form "hostdev%d", while the function that looks through
existing netdevs to determine the name to use for a new addition will
fail if there's an existing entry that does not match the form
"net%d".
This is another of the handful of places that need an exception due to
the hybrid nature of <interface type='hostdev'> (which is not exactly
an <interface> or a <hostdev>, but is both at the same time).

The libvirt collectd plugin predates support for memory statistics.
Therefore it would need to be extended to add this feature.
Patches for this best sent to the collectd project.

[libvirt] [PATCH][libvirt-glib] glib-events: Allow zero timeouts for timer
by Michal Privoznik
In libvirt, it's perfectly possible and widely used to have disabled
timers (timeout=-1) and fire them up 'randomly' with timeout=0.
However, with current mapping into glib mainloop it's not possible
and causing troubles.
