[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-users] PCI passthrough help!
Hi,
I am testing the PCI passthrough feature by using xen-unstable and Intel DQ35JO motherboard.
The passthrough seems not working. The PCI devices I want to hide still shows up in lspci. The HVM
creation failed with the following message:
VmError: Fail to assign device(0:1a.7): maybe VT-d is not enabled, or the device is not exist, or it has already been assigned to other domain
I have complied the PCI backend driver into Dom0 kernel and also turn on the PCI backend debug option.
The VT-d option in BIOS is enabled.
Following are my grub.config, hvm, and pciback debug output.
In grub.config:
title Xen 3.2 unstable
root (hd0,0) kernel /boot/xen-3.2.gz console=vga module /boot/vmlinuz-2.6.18.8-xen ro root=LABEL=/ rhgb quiet pciback.permissive pciback.hide=(00:1a.7)(00:1d.7 ) module /boot/initrd-2.6.18.8-xen.img In hvm file I add:
pci = ['00:1a.7']
Here is the dmesg | grep pciback:
Bootdata ok (command line is ro root=LABEL=/ rhgb quiet pciback.permissive pciback.hide=(00:1a.7)(00:1d.7))
