Hmm, yeah we should check that and throw a more clear error message.

However, the root cause is that your capabilities xml is screwy
(posted a few messages back.) There is only a <domain> element
for x86_64 qemu but you're host arch is reported as i686.

What libvirt version are you using?
What virt-install/python-virtinst version are you using?
Is kvm installed?
What distro are you on?
