[libvirt] [PATCH] virsh: Add a helper to parse cpulist
by Osier Yang
vcpupin and emulatorpin use same code to parse the cpulist, this
abstracts the same code as a helper. Along with various code style
fixes, and error improvement (only error "Physical CPU %d doesn't
exist" if the specified CPU exceed the range, no "cpulist: Invalid
format", see the following for an example of the error prior to
this patch).
% virsh vcpupin 4 0 0-8
error: Physical CPU 4 doesn't exist.
error: cpulist: Invalid format.

Interesting side note is that running the test singularly via 'make -C tests
check TESTS=qemuxml2argvtest' didn't trip the valgrind error; however,
running during 'make -C tests valgrind' did cause the error to be seen.

[libvirt] [PATCHv5 00/11] Introduce driver specific XML parsing callbacks
by Peter Krempa
This series now splits out everything unrelated from the virCaps object.
See notes in individual patches for change summary.
This series now contains 2 renaming patches that were suggested by Eric and
Laine.
Peter Krempa (11):
conf: Add post XML parse callbacks and prepare for cleaning of virCaps
conf callback: Rearrange function parameters
qemu: Record the default NIC model in the domain XML
virCaps: get rid of "defaultInitPath" value in the virCaps struct
virCaps: get rid of defaultDiskDriverName
virCaps: get rid of emulatorRequired
virCaps: get rid of defaultDiskDriverType
virCaps: get rid of hasWideScsiBus
virCaps: get rid of macPrefix field
virCaps: get rid of defaultConsoleTargetType callback
maint: Rename xmlconf to xmlopt and virDomainXMLConfing to
virDomainXMLOption

[libvirt] The problems of default settings
by Li Zhang
Hi all,
I am recently considering about the default setting for different platforms.
Currently, there is no good way to fix the default setting for PPC64
platform.
For example, we prefer pseries on PPC64 as the default machine type
users don't need to specify it.
I am thinking about the solutions.
1. One solution I am thinking about is to create template xml files for
different platforms.
But if users give their own configuration XML files, how to keep the
preferred configurations in domain definition.
I think this solution should be better in management tools, for example,
ovirt or openstack.
After management tools can generate its own configuration files with
different default settings,
libvirt can help create according to XML files.
2. Another solution is to use hook in libvirt.
But it seems that we need to use hook daemon. Is it complex to use?
I am not familiar with hook.
Any suggestion is appreciated.
Thanks. :)

[libvirt] migrate qemu domains
by Yin Olivia-R63875
Hi,
I tried to migrate qemu domains between same two Freescale PPC platforms.
1) Migrate test domain from Host1(10.193.20.109) to Host2(10.193.20.181).
root@ppc-host1:~# virsh migrate test qemu+tls://10.193.20.181/system
or
root@ppc-host2:~# virsh -c qemu+tls://10.193.20.109/system migrate test qemu:///system
I waited for a while and finally got error message as below:
error: Unable to read from monitor: Connection reset by peer
Exactly, when waiting (I guess during migration), the migrated domain is pasued on
both source and destination nodes.
root@ppc-host1:~# virsh -c qemu:///system list --all
Id Name State
----------------------------------------------------
5 test paused
And meanwhile, the destination domain is also paused when waiting
root@ppc-host2:~# virsh -c qemu:///system list --all
Id Name State
----------------------------------------------------
2 test paused
Finally, the migrated domain on source node is shut off.
root@ppc-host1:~# virsh -c qemu:///system list --all
Id Name State
----------------------------------------------------
- test shut off
But can't find any domain on destination node any longer.
root@ppc-host2:~# virsh -c qemu:///system list --all
Id Name State
----------------------------------------------------
As I know qemu-system-ppc doesn't support live migration on Freescale PPC platform yet.
My question is whether it depends on qemu implementation to migrate qemu hypervisor with libvirt?
>From the above experiment, it seemed that migration happened but not succeeded finally.
Best Regards,
Olivia
