xen discuss - Apr 2008 - Prebuilt OpenSolaris / Nexenta DomU with ZFS root?

Does anyone know of a prebuilt Solaris or Nexenta DomU with a ZFS root 
that uses paravirtualization?

I''ve been mulling over the directions for both, but my Xen DomU is 
Fedora for the moment.  (I hope to use OpenSolaris as my Dom0 at some 
point, but due to lack of hardware and time, I need to build the VMs 
first before I format my home-server.)

Thanks,
-Luke
