Re: [Xen-users] CentOS/Xen PCI pass-through
Hi Guys,
I have been trying to get PCI Passthrough working
for *MONTHS* now.
In the bottom half are the best instructions I've
seen so far for getting PCI Passthrough to work yet. It not only explains
it better than most places, but it allows you to see and understand what is
actually going on during the process. I now have successfully passed
through a network card and a video card to a DomU machine. (I've yet to
get the video card to actually work, but it's in the PCI list now)
Hope this helps,
Phil.

Subject: [Xen-users] CentOS/Xen PCI
pass-through
Is PCI pass-through available in the "standard" CentOS 5.1
kernel? From the "xm info" command, I see the major.minor version of Xen
is 3.1, so I'm assuming it is and that I'm missing something
basic.
I've tried using "pciback.hide=(...)" in grub.conf, but after
getting an error message about it not being valid, I realized that pciback is
a module, so it's not available.
So, I tried it in /etc/modprobe.conf,
but that apparently didn't work either. I also tried this (http://wiki.xensource.com/xenwiki/Assign_hardware_to_DomU_with_PCIBack_as_module?highlight=%28pci%29)
and it seemed to work -- I at least got a message about the pciback grabbing
the device. I do, however, still see the device when I do a "lspci", but
I'm not certain if that is normal or not.
I added the "pci = [ ... ]"
in my Xen domU config file but am not seeing the device in lspci (which is
totally empty), and am not sure what is up. Since I don't have the "xm"
commands in the domU, I'm not sure what to do.
I'd like to pass in my
video capture devices into a domU and get Myth or Sage running in one of my
domU's. Base OS is CentOS 5.1 x86_64 for sheer stability and
patchability; that way the domU can be tweaked/upgraded/rebuilt without
impacting anything else.
Any suggestions would be
appreciated!
-Rob
