IIUC, 'x86_64:i386' is claiming that you can run x86_64
KVM guests on an i386 host. I thought that was impossible,
only 32-on-64 being allowed not 64-on-32.

Same question here with ppc64:ppc suggesting you can
run 64-bit guest with KVM on a 32-bit host ?

This again is claiming support for 64-bit guests with Xen on a
32-bit host, which AFAIK is impossible.
