Re: [Xen-users] VGA Passthru - FLR?


First question: yes, it does work everytime I start the dom0 with my HD 7950 freshly booted as the secondary VGA (it never worked as primary though).

Using windows 7 ultimate 64bits, after rebooting due to windows update, the VGA won't work (only if I reboot dom0 as I said). Reaching the VM with VNC, the cirrus device seems to be okay, the radeon device tells me it co

Using Windows XP sp3 I managed to reboot the VM several times and everything worked.

Hi there,

I fear you have to be a bit more specific because with only that
information, this could be a lot..

But alright, let's start at the beginning:

I assume you installed your dom0, installed your windows domU via the
vnc vga, then installed latest catalyst drivers and at this point vga
passthrough should work..

So now let's assume you have a freshly booted dom0 and try to start
your domU. Does vga passthrough works every time on a freshly booted
Lets further assume it have worked the first time.. does it always
does not work when booting a second time?
What in general happens when you say vga passthrough doesn't work? Do
you get a BSOD? or do you get your graphic output on the vnc vga and
your main vga has a error 14 or error 43 in device manager?

Also, next to distro and kernel information, your domU config would be
interesting (especially the acpi, api, pci_whatever parts)..
