I don't see why VMware (a program that runs under linux) wouldn't be
able to run under a linux domain in Xen.  I haven't used VMware for
several years, but as far as I remember it is completely in userspace.
 Is there a specific reason why it would not work?  Has anyone tested
this?
VMWare doesn't run completely in userspace; it needs a kernel module to work. I suppose this is necessary for VMWare to run guest code destined to be in ring 0 (i.e. OS code). As Xen OSen run in ring 1 this won't work.
