Can you compare the output of 'virsh dumpxml' for the fast and the slow
domain? My guess is that you forgot to request KVM hardware acceleration
for the slow domain.  Look for '<domain type='kvm'> as well as for the
right <emulator> binary.  'However, I'm not familiar enough with the
libvirt-php bindings to suggest what to add to your code to get the
correct XML.
