Re: FW: [Xen-users] Re: [Xen-devel] Assigning a physical device to aparticular domain

[Sharath Babu <sharathx@xxxxxxxxx>]

(%02x:%02x.%1x) = (device's PCI bus Num: device Num. function Num)

By adding physdev_dom0_hide=(%02x:%02x.%1x) to the boot option, you are
hiding that perticular PCI device from Dom0 which is necessary.

Eg: physdev_dom0_hide=(00:04.1)

Then you would configure and compile the DomU kernel to include the pci device that you want to access from domU

Then export the PCI device to the domU by adding the following to your domU's configuration file

pci = ['0,4,1']

In the current Xen 3.0 unstable you cannot directly assign PCI devices
to domUs. It is possible with Xen 2.0.

In grub append this to your Xen line physdev_dom0_hide=(%02x:%02x.%1x)
