Hello Folks,
I've tried use bridging capability that comes in Mountain Lion kernel.
It works fine with other virtual interfaces like tap but it trigger kernel crash if you bridge vmnet interface.
pretty simple POC
start fusion
sudo -s
ifconfig bridge0 create
ifconfig bridge0 up addm vmnet8
You can use any vmnet interface and it will immediately trigger kernel crash. I've verified on couple of other computer
so it not computer specific.
Kind Regards,
Mustafa
