Following upstream patches need to be pulled in to fix this:

1. commit 450a59ba569f571e499d618be4bfde064122f1fc
Author: Martin Kletzander <email address hidden>
Date: Thu Apr 9 10:49:02 2015 +0200

    schema: Allow multiple machines for VMs and unite architectures

    Use the same pattern for all machine types on all archs and same archs
    for hvm and exe types.

Additionally, the following fixes are required for ppc64le : (not related to this bug, but need to be taken in)

1. commit 5e4f49ab8aa2dc7e71b8482e2f15f2a7de1c1006
Author: Prerna Saxena <email address hidden>
Date: Sun Feb 15 09:54:15 2015 +0530

    PowerPC : Forbid NULL CPU model with 'host-model' mode.

    PowerPC : Forbid NULL CPU model with 'host-model' mode in qemu command line.

    This ensures that an XML such as following:
    ...
      <cpu mode='host-model'>
        <model fallback='allow'/>
      </cpu>
    ...

    will not generate a '-cpu host,compat=(null)' command line with qemu-system-ppc64
2. commit bdbe723fcd8b55678b0ad984134f7b79d6fbeb89
Author: Prerna Saxena <email address hidden>
Date: Sun Feb 15 09:48:00 2015 +0530

    PowerPC : Make 'qemu-system-ppc64' the default emulator on ppc64[le].

    PowerPC : Explicitly associate 'qemu-system-ppc64' as the
     default emulator for all 64-bit PowerPC guests ( both Big & Little Endian )

Status changed to 'Confirmed' because the bug affects multiple users.

Debdiff with above fixes and builds against vivid's libvirt.
Once the current package in proposed gets worked through we should merge this with other libvirt fixes and upload into the next version.

Hey can we have this on utopic as well?

[Chris J Arges (arges)]

The backport to Utopic is not a clean cherry-pick to 1.2.8.
The following require a bit more support: 450a59ba569f571e499d618be4bfde064122f1fc 5e4f49ab8aa2dc7e71b8482e2f15f2a7de1c1006

Any idea for additional support patches? I'd like to confirm the failure in Utopic, and understand if there is a better strategy for this version.

Thanks,

Hello bugproxy, or anyone else affected,

Accepted libvirt into vivid-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/libvirt/1.2.12-0ubuntu14.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Hi Chris,
In response to comment #5:
1) 450a59ba569f57 : This is required. Reason :Qemu updates result in newer pseries* machine types being introduced, which are subsequently not recognized by libvirt.
I had proposed this patch to the community to fix this : https://www.redhat.com/archives/libvir-list/2015-April/msg00200.html
However, they relaxed the schema completely through commit 450a59ba569f57.
You could try introducing the fix at the above URL as a private patch in utopic, if the said upstream commit is difficult. It will address the problem at hand.
2) 5e4f49ab8aa2dc7e : This is a bug fix, and needs inclusion. Are you sure it is not getting properly patched in utopic ? It seems like a one-line change.
