The free XenServer is still limited to 4GB of RAM and 4 VM's per server. Also from what I can see, XenServer lacks the ability to do snapshots, which I really don't understand considering they're using LVM. And actually James has been making great strides with his GPLPV drivers, so freeware Xen is catching up to XenServer fairly fast, although it's still lacking good GUI tools. Hopefully soon James will release version 1.0 of his drivers, and I can finally consider using Xen in production. Russ
