Andre, I am not an expert, I only started using this a few weeks ago, but I think I can help a little..
What type of virtual disk were you using? For sure "flat file" on zfs is *very* slow. I use ZFS on all my (Open)Solaris domU's. I had problems with "sparse" file based disk images, so I switched. My "disks" are actually zvol's, shared over iscsi from a Unified Storage 7410c, but I also have a few "local" zvols. These perform well. I assume you followed the examples and advice at http://hub.opensolaris.org/bin/view/Community+Group+xen/virtinstall ?
