ACAIT from the spec file rules it isn't possible to successfully build the
KVM rpm and *not* get a /usr/bin/qemu-kvm built. That file is explicitly
listed in the %files section, so there's no way the RPM would be able to
finish building without it being created.
FYI, what I do to rebiuld src.rpms is:
# rpmbuild --rebuild --define 'dist .fc7' kvm-19-2.src.rpm
Verify it was built:
# rpm -qlp /home/berrange/rpm/RPMS/i386/kvm-19-2.i386.rpm | grep /usr/bin/qemu-kvm
/usr/bin/qemu-kvm

We recently added logic to virt-manager to 'guess' an appropriate hypervisor
URI based on the host kernel being run. We should probably do similar in
the virt-install case.

Yes, that's a bug - its trying to auto-setup the guest with bridge networking
and not finding any bridges, so (incorrectly) falling back to xenbr0 which
it just verified doesn't exist !
