VMPlayer 3.0

I am considering setting up a Windows 7 Professional 64 bit/Ubuntu 9 VM configuration. I have never done this before.

The VMPlayer 3.0 Documentation does NOT list 64 bit Windows - Professional on either the host or client list. Windows 7 Professional 32 bit is listed.

Does anybody know why the 64 bit version is not valid for VMPlayer 3.0 use?

Also, there were a couple of posts describing seriously degraded performance with VMPLayer 3.0 and Windows 7.

Comments will be appreciated
