Hello,
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.
