Re: [Xen-users] PCI Passthrough -- Gentoo Linux 3.0.4

[Felix Kuperjans <felix@xxxxxxxxxxxxxxxxxx>]

Hi Ryan,

the Gentoo 3.0.4-gentoo-r2 kernel is a mainline kernel with Gentoo patches and AFAIK lacks pci passtrough support (added in 3.1, but this one will be stable soon).

You might want to use some other kernel sources with XEN patches for pci backend or try the latest 3.1 RC. Be sure to enable pci backend there.

Regards,
Felix

Hi All,

Was up real late last night trying to get this to work and still couldn't -- driving me nuts. I had PCI Passthrough working on this box when it was running OpenSUSE. I decided to move back to Gentoo/Funtoo as I'm going to be doing more source based installs of supplemental software (SCST) and like the compile-based stack of Gentoo.

System is running 3.0.4 kernel and booted by Grub2. All necessary bios options have been enabled; this was working on a prior OS.

Here's a few configuration files / outputs:

san ~ # uname -a

Linux san 3.0.4-gentoo-r2 #5 SMP Tue Oct 4 01:09:55 EDT 2011 x86_64 Intel(R) Xeon(R) CPU X3440 @ 2.53GHz GenuineIntel GNU/Linux

Thanks in advance!
