libvirtd log

Description of problem:

i686 guests can't be created.

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


Steps to Reproduce:
1. Just try to install one in virt-manager

Actual results:

Oct 16 20:20:37 goatlord.localdomain libvirtd[574]: Preferred CPU model coreduo not allowed by hypervisor; closest supported model will be used
Oct 16 20:20:37 goatlord.localdomain libvirtd[574]: internal error: Cannot find suitable CPU model for given data

Expected results:

No error.

Additional info:

My machine is a T60 with a coreduo cpu. i486 or anything else won't work either.

Comment 2 Lubomir Rintel 2014-10-16 19:40:13 UTC
I suspected this is due to the aarch64 patch. I downgraded the package to the 1.2.8 version and things started to work. However upon subsequent upgrade it still worked.

Could it be that I had something bad cached in /var/cache/libvirt/qemu/capabilities?

Comment 3 Lubomir Rintel 2014-10-16 19:40:53 UTC
That said, virt-manager still complains, despite it's a different issue now: https://www.redhat.com/archives/libvir-list/2014-October/msg00488.html

    qemu: x86_64 is good enough for i686
