the current version of QEMU emulates the VMware backdoor I/O port and it works quite well. Unfortunately it doesn't emulate the VMware behavior of ignoring the I/O permissions when accessing this special port. The attached patch corrects it. It's important to ignore the permissions, so that user mode VMware tools can communicate to the backdoor. =

I really dislike that VMware relies on this. It's very hard to implement in kqemu or KVM. I think it would be better to modify open-vm-tools than to modify QEMU.
