Hi,

PCI passthrough for multiple device not working

I have install xcp-xapi package and created one Ubuntu domain(domU).

For PCI passthrough I did-

On dom0
root@dom0:~# xe vm-param-set other-config:pci=0/0000:00:00.0,1/0000:00:1b.0 uuid=11ee7266-1de8-a8fa-f786-db3dce38680c

On domU
root@dd-domu:~# lspci
00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor DRAM Controller (rev 09)

Here I can only see single device, I want to passthough multiple devices.

Please let me know what I am missing here.
