This is what I have in my /etc/init.d/boot.local to disable VMware in
case Linux is booting on a Xen dom0:
if [ -s /sys/hypervisor/type ]; then
if [ "$(cat /sys/hypervisor/type)" = "xen" ]; then
: echo Add stuff for Xen kernels here
[ -s /etc/init.d/vmware ] && \
insserv -r /etc/init.d/vmware
fi
else
: echo Add non Xen stuff here
[ -s /etc/init.d/vmware ] && \
mount /proc/bus/usb
fi
