Dear Magee,
Any luck with the Intel vga passthrough
patches to xen 3.5-unstable on Intel DQ45CB with extra PCI-e x16 graphics card?
Are you using pvops dom 0 kernels 2.6.30-rc3 and 2.6.31-rc6?

That was the problem, thank you.
Now I’ll work on testing the gfx-passthrough patches.

I suspect you are using old hvm config
file. The device_model is changes in config file.
in old config file:
# New stuff
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
in new config file:
# Device Model to be used
device_model = 'qemu-dm'
Pls check it, and use the latest config
file to create guest.

Weidong

pci passthrough
I
have not been able to passthrough any PCI devices using the latest
xen-unstable. I have a DQ45CB, and have successfully passed devices to
guests using 3.4.1.
The
latest c/s in my copy of xen-unstable is 20145. I just started playing
around with unstable yesterday, so I can’t tell you if earlier revisions
worked. I’ve tried with various dom0 kernels, the current 2.6.18.8-xen
branch, a xenified 2.6.29.6, and a pvops 2.6.31-rc6, and in every case I get
the same error. I’ve tried both putting pci= in the config file, and
hot-adding the device using xm pci-attach. In every case, the xm command
(either create or pci-attach) fails with the message “Error: Timed out waiting
for device model action”. The guests in every case are HVM guests, some
flavors of Windows, as well as the Knoppix 5.3.1 DVD.
The
relevant xm dmesg output is:
(XEN) PCI add device 00:1b.0
(XEN)
[VT-D]iommu.c:1292:d0 domain_context_unmap:PCIe: bdf = 0:1b.0
(XEN)
[VT-D]iommu.c:1178:d0 domain_context_mapping:PCIe: bdf = 0:1b.0
(XEN)
[VT-D]io.c:284:d0 VT-d irq bind: m_irq = 37 device = 3 intx = 0
(XEN)

(XEN)
[VT-D]iommu.c:1178:d0 domain_context_mapping:PCIe: bdf = 0:1b.0
And
the messages from qemu-log:
dm-command:
hot insert pass-through pci dev
hot
add pci slot -2 exceed.
Please
let me know what else I need to supply to help resolve this problem. If I
need to enable debugging messages, let me know the best way to do this.
