I overread the virsh - sorry.

/* XXX future KVM will support SMP. Need to probe
   kernel to figure out KVM module version i guess */
if (STRCASEEQ(type, "kvm"))
   return 1;

There's a KVM_NR_MAX_VCPUS capability in recent KVM but this won't be
working until 2.6.27 so there's little point in fixing this for lenny
yet. I'll push a patch upstream - should we get 2.6.27 into lenny I'll
backport it, otherwise it will get into unstable with the new upstream
libvirt version.
Cheers,
