Yes it does matter because I am trying to figure out why your
capabilities xml is messed up.
 
Here is a piece of the capabilities xml you posted:

  <guest>
    <os_type>hvm</os_type>
    <arch name='i686'>
      <wordsize>32</wordsize>
      <emulator>/usr/bin/qemu</emulator>
      <machine>pc</machine>
      <machine>isapc</machine>
    </arch>
    <features>
	...
    </features>
  </guest>

This piece here should have a <domain> element, but since
it doesn't that means libvirt didn't have executable access
to /usr/bin/qemu. Is this named differently on Ubuntu? How
about all the other binaries (qemu-system-mips, ...)?

  <guest>
    <os_type>hvm</os_type>
    <arch name='x86_64'>
      <wordsize>64</wordsize>
      <emulator>/usr/bin/qemu-system-x86_64</emulator>
      <machine>pc</machine>
      <machine>isapc</machine>
      <domain type='qemu'>
      </domain>
    </arch>
    <features>
	...
    </features>
  </guest>

If kvm is installed, then this should have a kvm <domain>
entry. Is /dev/kvm present/kvm module loaded? Is
/usr/bin/qemu-kvm present?

Thanks,
