I had many troubles with Virt-manager & debian. However Xen workt "out
of the box"
Xen version
4.1
Dom0 kernel version, and if it''s pvops or xenlinux based
3.1.0-1-amd64 (Debian testing aka wueezy install)
"lspci" output for the graphics card to get the PCI IDs and model
information
- primairy (Xwindows console not used for xen)
ATI Technologies Inc RV570 [Radeon X1950 Pro] (rev 9a) (prog-if 00 [VGA
controller]
03:00.0 0300: 1002:7280 (rev 9a)
03:00.1 0380: 1002:72a0 (rev 9a)
- secondairy VGA (used for passthrough)
ATI Technologies Inc RV710 [Radeon HD 4350] (prog-if 00 [VGA controller])
05:00.0 0300: 1002:954fAudio device: ATI Technologies Inc RV710/730
05:00.1 0403: 1002:aa38
08:00.0 0200: 8086:10d3
- pci (not PCIe audio device)
Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 07)
09:02.0 0401: 1102:0002 (rev 07)
09:02.1 0980: 1102:7002 (rev 07)
Did you passthru all the PCI IDs or just one?
Was it primary or secondary graphics adapter?
secondary (3d to be added later on)
Motherboard vendor/model and BIOS version.
Intel DX58SO2 Bios version 824(latest of this date)
# xm dmesg output
----------------------------
(XEN) Intel VT-d Snoop Control not enabled.
(XEN) Intel VT-d Dom0 DMA Passthrough not enabled.
(XEN) Intel VT-d Queued Invalidation enabled.
(XEN) Intel VT-d Interrupt Remapping enabled.
(XEN) Intel VT-d Shared EPT tables not enabled.

# cat /boot/grub/grub.cfg
--------------------------
multiboot /boot/xen-4.1-amd64.gz placeholder intel_iommu=on
--------------------------
ps this grub setting has no effect ??
Guest OS and driver version.
Windows 7, default ATI HD 43xx driver for OS (not default included) and worked
after reboot ..
How did it work.. did you have some issues?
PCIback not available on debian this was a bit of an issue (no howto to find how
to enable or activate this (grrr)
, however pci_stub module was default available .. now to "keep after
reboot" instead of ugly sript after reboot.
No Patch needed for making VGA passthrough work .. default install.
However
--------------------------# chmod 777
/var/run/libvirt/libvirt-sock--------------------------
Was needed to make virt-manager work
Actually I prefer more the option to "PCI_Stub" the devices at guest
boot time, and releasing at "shutdown/crash/"
and a less "complex" method of making "xm
pci/usb-list-assignable-devices" work why not make "select
device" to add to your "selected" domain ?
prefferably making 1 method to "re-allocate" to domain0 "in case
of ... emergency" or "pinning" a default set of ports for Domain0
