[libvirt] [PATCH] docs: Make anchors follow HTML5
by Michal Privoznik
According to HTML specification, <a name=''> works in HTML4, but
<a id=''> works in both HTML4 and HTML5. This is followed even in
docs/page.xsl where HTML bookmark links are generated only for
those anchors which have @id attribute.
Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com>

For instance, ToC at the following page doesn't work:
https://libvirt.org/hvsupport.html
But after this patch the links are generated properly.

[libvirt] [PATCH v2 2/4] audio: omitting audiodev= parameter is only deprecated
by Kővágó, Zoltán
Unfortunately, changes introduced in af2041ed2d "audio: audiodev=
parameters no longer optional when -audiodev present" breaks backward
compatibility. This patch changes the error into a deprecation warning.

This patch is a little different with the original commit, since we only prefer live XML
when using LIVE AND CONFIG flags at the same time. Still parse separate device def if attach with only one flag.
So this patch is kinda a combination of 1e0534a7702 and 55ce6564634, just to narrow down the problem influence.
And I verified as the steps in https://bugzilla.redhat.com/show_bug.cgi?id=1559867, work as expected.

[libvirt] [BUG] When PLUG a bridge interface to an active VM, the generated LIVE and CONFIG mac address are different
by Xu Yandong (Yandong Xu)
Hi,
When plug a bridge interface to an active VM with both LIVE AND CONFIG flags,
libvirt generate different mac address to LIVE and CONFIG instance, so After
I reboot the VM, DHCP server doesn't assign the same IP address to the new
bridge interface.
Steps:
1. Having running VM
## virsh list
Id Name State
-------------------------------
1 centos_7.6_64 running
2. Prepare a bridge interface xml
## cat interface.xml
<interface type='bridge'>
<source bridge='br0-int'/>
<virtualport type='openvswitch'>
</virtualport>
<model type='virtio'/>
<target dev='ovsvnet4'/>
</interface>
3. Plug interface with --live and --config
##virsh attach-device centos_7.6_64 interface.xml --config --live
Device attached successfully
4. Check LIVE XML
## cat /var/run/libvirt/qemu/centos_7.6_64.xml | grep ovsvnet4 -A 4 -B 6
<interface type='bridge'>
<mac address='52:54:00:23:7d:fb'/>
<source bridge='br0-int'/>
<virtualport type='openvswitch'>
<parameters interfaceid='c9f07f2b-3888-4f25-bd80-f5ba04d07bf8'/>
</virtualport>
<target dev='ovsvnet4'/>
<model type='virtio'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
</interface>
5. Check Config XML
## cat /etc/libvirt/qemu/centos_7.6_64.xml | grep ovsvnet4 -A 3 -B 6
<interface type='bridge'>
<mac address='52:54:00:bb:d4:53'/>
<source bridge='br0-int'/>
<virtualport type='openvswitch'>
<parameters interfaceid='189234ea-878e-4e8a-9f63-f43fac50aebd'/>
</virtualport>
<target dev='ovsvnet4'/>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
</interface>
The mac address and virtualport interfaceid does not match in LIVE and CONFIG XML.
This phenomenon was introduced by the commit:
commit 55ce65646348884656fd7bf3f109ebf8f7603494

qemu: Use the correct vm def on cold attach
https://bugzilla.redhat.com/show_bug.cgi?id=1559867
When attaching a device to the domain we need to be sure
to use the correct domain definition (vm->def or vm->newDef)
when calling virDomainDeviceDefParse because the post parse
processing algorithms that may assign an address for the
device will use whatever domain definition was passed in.

[libvirt] [jenkins-ci PATCH v2] guests: Introduce a var to enable shallow git clones for projects
by Erik Skultety
First of all, we don't need the full history for builds and we can save
some time during the prepare phase. The disk footprint is about 5x
smaller, but the most important thing is the repo clone duration
difference e.g. in libvirt's case is quite significant:
full history:
real 3m45.236s
user 1m53.074s
sys 0m15.577s
depth 1:
real 0m14.868s
user 0m2.215s
sys 0m0.906s
Since jenkins has a local copy and doesn't clone from the internet, this
patch modifies only the configs for local VMs.
