That was fixed back in 2007 with a simple addition to your machines .vmx

I have used VMware for years without problems and find the workstation stable enough to run machines for months at a time without having to reboot for anything other than updates to the host they reside on.

I am not opposed to VirtualBox and have recommended it to others when they don't want to pay for VMware but I didn't find it as fluid, though I am used to VMware so I may be a little partial.

Though you can disable the host-guest communication/"backdoor" port, most people won't and it can become a serious problem for them.
Anyway, I do understand that it's not an issue for someone who knows what they're doing. Nothing is.
