Hi @all,
I have many domU on my server and they work fine, some of them have
their
own NICs with the PCI param in the config.
Now I try to bring a soundcard for asterisk into a new domU and have
the
following trouble:
rz3-ta:~ # lspci
00:00.0 Multimedia audio controller: Creative Labs SB Audigy (rev 04)
PCI: Enabling device 0000:00:00.0 (0000 -> 0001)
EMU10K1_Audigy: probe of 0000:00:00.0 failed with error -12
I don't find a solution howto get the card working. In dom0 it works
fine.
Have anybody a hint for me?
Have you tried pci.permissive on the kernel command line? (equivalent
to an option to loading the pciback module)
I don't know which options to try :(
In your grub configuration do you have the pciback.hide option there?
no, I tried this with the NICs, but it doesn't work, so I do it manually ...
Or do you give the device over to pciback manually?
yes:
echo -n 0000:0f:01.0 > /sys/bus/pci/drivers/EMU10K1_Audigy/unbind
echo -n 0000:0f:01.0 > /sys/bus/pci/drivers/pciback/new_slot
echo -n 0000:0f:01.0 > /sys/bus/pci/drivers/pciback/bind
At the point of passing it over, either with grub or manually, you
should have the chance to pass pciback.permissive
I don't know pciback.permissive, the soundcard is detected by alsa, but it
stops working with the mentioned error message in domU
Other than that, could it be the driver not working properly in the
guest?
dom0 and domU are the same
The kernel and ramdisk are the same?
I think so, it's a openSUSE Standard install.
Is the module loading in the guest properly?
in the dom0 yes, in the domU not, the error ist
EMU10K1_Audigy: probe of 0000:00:00.0 failed with error -12
