I'm having bad luck with Windows 7 64-bit VMs running on HP Z400 and Z600 workstations. Running VMware Player 6.0.1 build-1379776. The guest randomly freezes up and the only thing I can do is force a power off. The problem appears only to occur on the Z400 and Z600's. I run the same setup on an HP Elitebook 8440p with no problems. I've had similar problems with Workstation.
Where can I look to troubleshoot?
