Re: [Xen-users] Does direct HW-Access work in 3.0.2
Me again,
i found the reason why it isn\'t working. The PCI backend was compiled as
a module (SuSE 10.1RC1).
Currently i am compiling a new xen-kernel, but i am curious:
Is it possible to use the PCI backend driver if it is compiled
as a module?
I tried the following without success:
# modprobe pciback \'hide=(00:07.1)\'
Greetings,
-timo
