When starting oneiric as a xen hvm domain (from oneiric), passing through vga,
usb & audio, the audio device seems to cause xen to fail pvops initialization.
The xen domu is running oneiric with kernel 3.0.0-12-server, symptoms are the
same for 3.0.0-11-server.
My old ubuntu maverick installation works properly on the same host.
The xen config file for the hvm looks like this:
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 900
device_model='/usr/lib64/xen/bin/qemu-dm'
name = "yavin"
vcpus=8
vif = ['mac=aa:00:00:00:01:09,bridge=loc']
disk = [
'phy:/dev/vm/yavin-oneiric,ioemu:hda,w',
'file:/images/ubuntu-11.10-beta2-server-amd64.iso,hdc:cdrom,r',
]
boot="cd"
sdl=0
vnc=1
vnclisten="0.0.0.0"
vncdisplay=9
vncunused=1
stdvga=0
serial='pty'
monitor=1
pci = [
'0000:06:00.0', # 06:00.0 usb
'0000:02:00.0', # 02:00.0 fglrx (tried radeon as well)
'0000:02:00.1' # 02:00.1 snd_hda_intel
]
Relevant part of the boot messages:
Loading, please wait...
[ 2.401864] udevd[106]: starting version 173
Begin: Loading essential drivers ... [ 2.456569] xen map irq failed -22
[ 2.475372] xen-platform-pci 0000:00:03.0: PCI INT A: failed to register GSI
[ 2.509994] xen-platform-pci: probe of 0000:00:03.0 failed with error -1
The above error results in the xdv* devices not being created, and thus i'm
stuck at the initramfs prompt.
Commenting out the audio device from the above configuration makes things work
(albeit without sound).
