Comment 3 for bug 2046544

I believe that 0.3 improves the situation, because it now passes `-cpu max` rather than `-cpu host` and thus improves the fallback behavior.

Additionally, I think this is a bug in Ubuntu's infrastructure, because the `/dev/kvm` device is writable to the autopkgtest user and not working. Earlier versions of debvm would notice an inaccessible `/dev/kvm` and not attempt to use kvm in that case. Having the infrastructure remove or chmod the broken `/dev/kvm` device would also fix the test.
