[libvirt] [PATCH] qemuxml2argvtest: Fix test after change of qxl vgamem_mb default
by Michal Privoznik
Well, apparently it's possible for a patch to sneak in through
review process and break 'make check'. It happened just lately
with 0e502466acb84a which changed the default of vgamem_mb for
qxl device. However, there were left some domain XMLs within our
test suite relying on the old default. These should be updated to
match the change.

Re: [libvirt] Error starting domain: internal error: missing IFLA_VF_INFO in netlink response
by Hong-Hua.Yin＠freescale.com
Hi Laine,
Sorry to disturb you.
It seemed this issue had been fixed in libvirt-1.2.2/libnl-3.2.22/linux-3.12. But we still got the error on PowerPC platform.
I'll appreciate if you could give any suggestion. We are not sure if any netlink implementation in kernel space is missed.
The scenario is a little complicated. We installed internal PF and VF kernel modules and want to use
<interface type="hostdev" managed="yes"> syntax to start a guest domain with MAC address.

[libvirt] [PATCH 0/6] Resolve some Coverity errors and other issues found
by John Ferlan
With the build fix, my coverity build worked again (good), but found
more issues (boo).
Consider these changes partially as a replacement for Pavel's patch:
http://www.redhat.com/archives/libvir-list/2015-January/msg00240.html
with some additional changes for checks that need to be made in failure
path scenario. I didn't make any of the code formatting changes Pavel
had made for virDomainNetIpsFormat, but I can do that. I just wanted to
get these on the list for a comparison. Additionally, Pavel's change for
virDomainNetRoutesFormat didn't take into account that the alloc's are
done in a for loop, so both the VIR_FREE's needed to be done in the loop.
There are still some Coverity issues left over after this, but I'm not
quite sure how to fix them, hence the reply on the Xen-xl parser:
http://www.redhat.com/archives/libvir-list/2015-January/msg00243.html

[libvirt] [PATCH] cpu: Bugfix for s390 CPU driver to return a host CPU model
by Daniel Hansel
The curent libvirt CPU driver for s390 does not return a host CPU model.
This patch returns 'host' according to the other platforms that would
not decode any CPU model.
This is an intermediate bugfix due to a discussion on OpenStack mailing
list. The final patch introducing the CPU model support for s390x will
exchange the hard-coded decode method.

[libvirt] [PATCH] qxl: change the default value for vgamem_mb to 16 MiB
by Pavel Hrdina
The default value should be 16 MiB instead of 8 MiB. Only really old
version of upstream QEMU used the 8 MiB as default for vga framebuffer.
Without this change if you update your libvirt where we introduced the
"vgamem" attribute for QXL video device the value will be set to 8 MiB,
but previously your guest had 16 MiB because we didn't pass any value to
QEMU command line which means QEMU used its own 16 MiB as default.
This will affect all users with guest's display resolution higher than
1920x1080.

[libvirt] [PATCH v2] docs: Document some -boot option limitations on UEFI
by Michal Privoznik
It was brought to my attention that some -boot options may not
work with UEFI. For instance, rebootTimeout is very SeaBIOS
specific,splash logo is not implemented yet on OVMF, and so on.
We should document this limitation at least.

[libvirt] [PATCH] qemu: Allow enabling/disabling features with host-passthrough
by Martin Kletzander
QEMU supports feature specification with -cpu host and we just skip
using that. Since QEMU developers themselves would like to use this
feature, this patch modifies the code to work.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1178850

[libvirt] [PATCH V4 0/5] support sending sysrq key
by Chunyan Liu
xend/libxl support sending sysrq key to guest kernel but not support
sending any key sequence as virDomainSendKey is expected to do. To
add equivalant sysrq functionality in libvirt for xen/libxl, add a new
virDomainSendSysrq API and add related codes to virsh, remote driver,
xen/libxl driver.
Changes to V3:
* fix some memory leak
Not change:
virDomainSendSysrq parameter still keeps "char key" rather than "enum
key", main reason to keep it because: sysrq key is different to different
kinds of guests, xen hypervisor doesn't know the correct enum <-> letter
mapping towards different guests, it just sends the key blindly to guests.
See:
http://www.redhat.com/archives/libvir-list/2015-January/msg00132.html
V3 is here:
http://www.redhat.com/archives/libvir-list/2014-December/msg00882.html
Chunyan Liu (5):
Add public API virDomainSendSysrq
implement remote protocol for domainSendSysrq
virsh: add 'sysrq' command
libxl: implement .domainSendSysrq method
xen: add .domainSendSysrq method
