[Qemu-devel] [PATCH 1/3] S390: Basic CPU model support |
Date: |
Fri, 23 Nov 2012 11:18:10 +0100 |
From: Viktor Mihajlovski <address@hidden>
This enables qemu -cpu ? to return the list of supported CPU models
on s390. Since only the host model is supported at this point in time
this is pretty straight-forward. Further, a validity check for the
requested CPU model was added.
This change is needed to allow libvirt exploiters (like OpenStack)
to specify a CPU model.
