According to the documentation, Novell recommends installing the groupwise on vmware, hyper-v, but when it comes to Xen on SLES 11sp3, they say "Large post offices with busy Post Office Agents are not good candidates for Xen virtualization. Specialized Post Office Agents, such as an indexing Post Office Agent with no mailboxes and users, could be virtualized using Xen. Other GroupWise components such as the Message Transfer Agent and the Internet Agent do well when virtualized using Xen". Can i install the 50 users on a Xen machine, the mobility server on another and have it work fine? I have it running in my office on Xen and no issues, of course we are just 5 people...
