[Xen-devel] RE: [XCI] result of pci vga passthrough

[Tim Moore <timothy.moore@xxxxxxxxxxx>]

Stefano / Jean,

I am looking through these logs and nothing seems to be wrong ! no error 
mapping i/o or mem for Xen or Qemu, for all intents and purpose this should 
work? I feel like i`m cracking up!

Additional info attached.

What IS strange is that the card is detected as PCIe V1.0 not V2.0 which it is. 
When using pv DomU this does show as a PCIe v2.0 card ... but not under HVM.

Cheers,
Tim

Hi Stefano,

Please find attached, logs from XCI and a quick jpg of the WinXP host.

I will compile Xen for XCI with debug if necessary?

Cheers,
Tim

In this case you are interested in the qemu and xen logs.
For qemu, just open /var/log/xen/qemu-dm-guestname.log; for xen
compile the hypervisor with debug = y (in Config.mk) and keep an eye on
the serial.
