I'm have a terrible time running almost any VM's on top of Workstation 10.1 on a Win7 x64 host.
The only guest that works reliably is a Ubuntu 12.04 64 bit guest running kernel 3.8.0-33-generic.
The rest will boot up fine but don't allow any keyboard or mouse interaction - if you enable VNC VM sharing, however, you can drive their UI's fine - so the VM's are running but are just not getting any keyboard or mouse events.
I have a CentOS 6.5 x64 guest running 2.6.32-431.el6.x86_64, another 12.04 x64 running 3.2.0-56, and a 10.04 Ubuntu running 2.6.32-47-generic - none can be interacted with from the console view. The ones that can enter unity mode will also allow interaction, but Unity is still buggy enough that isn't much of a solution either.
Is anyone else seeing this sort of behaviour?
