Re: [Xen-users] Dom0 freeze on HVM DomU Windows reboot with VGA passthrough

        I've been away for a few weeks and I'm finally back on trying to figure
out this problem.


        I was using xl + xl pci-assignable-add when I get the full
machine freeze when I reboot the domU windows7.


        I just tried with the same domu config file, but with xm +
pci-stub, and I do not seem to get the freeze (yet, so far 3 reboots/shutdowns).


        The VGA passthrough (an HD7770) is still working even after the
reboot (i.e. no more blank screen).


        This is semi-good news. If the bug is in xl, then I guess we
will have to debug this since xm is deprecated.
