Just re-run  virt-install, passing in the /dev/hda2  as the guest file
system. When the installer pops up, instead of doing an install (which
would overwrite your guest), simply use 'virsh destroy' to shut it down
immediately. The neccessary guest config file should now have been created
so you can re-start with 'virsh start' as usual. 

I intend to add some form of 'virt-import' tool do make this more simple,
so you don't have to do the 'boot the installer & quit' trick.
