In FC6 GA you have to make sure the file for the disk was under /xen
to be labelled correctly. In rawhide (and the latest FC6 policy)
we're moving to /var/lib/xen/images. This is consistent with the
directory used on Suse, and what the next version of XenD will
enforce. To double check what directory is setup for the SELinux
policy you can run

  semanage fcontext -l | grep xen_image_t

If you don't have space under /var/lib/xen/images, then either
mount a new volume there, or bind that dir to a location which
has extra space, eg

    mount --bind /some/dir/with/big/disk  /var/lib/xen/images

If you really really don't want to use /var/lib/xen/images at all,
then you can define a new location in the SELinux policy using:

   semanage fcontext -a -f "" -t xen_image_t '/some/directory(/.*)?'
