Re: [Xen-users] Does direct HW-Access work in 3.0.2

[Timo Benk <timo.benk@xxxxxx>]

Hmmm,

i want to give direct IDE access to one of my domains:

# lspci
---<snip>---
00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
---<snap>---

I configured grub:

---<snip>---
title XEN - IDE hidden
    root (hd0,0)
    kernel /boot/xen.gz
    module /boot/vmlinuz-xen root=/dev/sda1 vga=0x314  \\
      resume=/dev/sda2  splash=silent showopts pciback.hide=(00:07.1)
    module /boot/initrd-xen
---<snap>---

And the domain in question:

---<snip>---
# direct hardware access
pci = [\'00:07.1\']
---<snap>---

However, \'xm dmesg\' print no message, indicating that the device is really
hidden.

When i start up the domain i get the following message:

---<snip>---
Error: pci: PCI Backend does not own device 0000:00:07.1
See the pciback.hide kernel command-line parameter or
bind your slot/device to the PCI backend using sysfs
---<snap>---

If i try to use sysctl i get the following message:

# sysctl \'pciback.hide=(00:07.1)\'
error: \"pciback.hide\" is an unknown key

Am i missing something or can somebody point me in the riht 
direction?

Thanks and greetings,
-timo
