        I believe you would have to buy different hardware to do this.  Very
few motherboards support running an onboard video card alongside an add-on
video card.  However, adding a PCI video card for your debugging might work
(I don't really know on that, and it could depend on the mobo as well,  it's
just a thought).

Subject: [Xen-users] PCI-E Passthrough - Missing VGA-Output

Dear Users,

in my case, i want to passthrough a pci-e graphiccard to a hvm guest.
In the bios i have to select whether the onboard graphic is used as
primary vga output or the pci-e one.

If i define the onboard one then the pci-e card gets unavailable in
xen, furthermore lspci did not show it anymore.

if i set the pci-e card as primary, it comes up fine in xen, but if i
hide that card which is required for passthrough, vga output becomes
unavailable.

vga output stops right after that line:

Event-channel device installed.
netfront: Initialising virtual ethernet driver.

how can i force the vga output to the onboard card? its just for
debugging purpose to have an output at all.

Regards

-- 
Stefan
