Re: [Xen-users] Audio PCI passthrough issues in a Linux domU

[Arjen <arjenvanweelden@xxxxxxxxx>]

Hi OJ,

I bought an Intel 3770S and an ASRock H77M that provides a working VT-D 
setup. I run a minimal Gentoo dom0 with efibootmgr, grub2 and 
xen-4.2.1-r2 (all ~amd) using the onboard Intel HD4000 and a PS/2 
keyboard. I have no X installed and are just now setting up Alsa to test 
the onboard audio on the dom0. OpenSUSE 12.3 runs fine on the bare metal 
with onboard Intel VGA.
My recently bought a HIS Radeon HD7750 iCooler that works using 
secondary VGA passthrough with decent OpenGL 4 support on OpenSUSE 12.3 
HVM. Note that I have to reboot dom0 before restarting this domU. I use 
the fglrx driver as there are no open source drivers for the HD7xxx's 
with OpenGL 3.2 yet. USB2 passthrough works fine. I trying to 
passthrough the onboard Intel HD Audio as well but am getting very 
choppy sound in the domU.
I successfully run Mythbuntu 12.04.2 (amd64) as a HVM domU with PV 
drivers, but I have yet to try my Hauppauge PVR-150 PCI tv-card. If that 
does not work via passthrough, I'll probably buy a USB2 tv-stick 
instead. I could also boot Ubuntu 12.04.2 and 13.04 live CD but did not 
try to install them.
For both domU's I have to specify the boot disk as hda, because Grub 
won't boot if I specify it as xvda. I provide the root, home and swap 
virtual disks via LVM2. Both use PV network drivers and DHCP via my 
router. The primary VGA is 'stdvga' because that worked a little better 
than Cirrus emulation. I currently use a VNC program from another PC to 
interact with both domU's. All domU's use their distribution's default 
(desktop) kernels and pci_msitranslate, pci_power_mgmt, xen_platform_pci 
are enabled.
Does this help you, or is there anything more specific that you would 
like to know?
kind regards, Arjen
