Description Marti Raudsepp 2012-02-17 18:18:38 UTC 
Description of problem:
I'm trying to get an ARM virtual machine image running within libvirt. The Fedora wiki [1] links to an example domain XML file [2], which reportedly worked in libvirt 0.7.6. But when I try to use the same XML in libvirt 0.8.8, I get the error:
error: internal error os type 'hvm' & arch 'arm' combination is not supported

According to the domain XML documentation [3], "hvm" and "linux" are the two possible values to use inside <type>. Neither of these are accepted with arch=arm, however.

This problem was also reported on the mailing list by someone else, but got no replies [4]

[4] https://www.redhat.com/archives/libvirt-users/2012-January/msg00036.html

Version-Release number of selected component (if applicable):

Compiled against library: libvir 0.8.8
Using library: libvir 0.8.8
Using API: QEMU 0.8.8
Running hypervisor: QEMU 0.14.0
(Ubuntu 11.04)

How reproducible:
Always

Steps to Reproduce:
1. Create domain
2. Edit and change <type> element to: <type arch="arm" machine="versatileab">hvm</type>

Actual results:
error: internal error os type 'hvm' & arch 'arm' combination is not supported

Expected results:
no error

Here's the output of capabilities.xml. No hint about ARM, even though I have qemu-arm installed. Is this a bug in Ubuntu's configuration?
Comment 3 Cole Robinson 2012-03-04 20:36:13 UTC 
Hmm, I'm guessing so. If qemu-arm is installed but libvirt isn't noticing it, could be an ubuntu specific issue or an old libvirt bug, since that version isn't current. I can't reproduce here on fedora with latest upstream.

I'd recommend filing a bug with ubuntu. Closing as WORKSFORME
