Re: [Xen-users] Syntax for PCI Pass-Thru for multiple devices?

[Age_M <Age_M@xxxxxx>]

Hi Daniel,

try this:

pci = [ '01:08.0','01:09.0' ]

If it still doesn't work, try using noirqdebug. I am not sure if you 
have to add it to your grub config or at the extra line in domU config 
but it resolves Problems with PCI devices sharing one IRQ. Maybe you 
just google it, to get the full information on this.
Good luck,
Age_M
