[Xen-users] Xen with infiniband

["Lamia M.Youseff" <lyouseff@xxxxxxxxxxx>]

Hi,
I am trying to get Xen working over infiniband connectivity. I was able 
to get up Dom0 to work with infiniband, but not DomU.
I am using Xen 3.0.2 with vmlinuz-2.6.16-xen and initrd-2.6.16-xen.img 
for DomU kernel and ram image respectively.
I am getting the error of  "Unknown symbol in module" when i am trying 
to insert infiniband modules ib_mthca.ko and ib_umad.ko to domU kernel. 
I made sure that the kernel was configured with infiniband support. 
However, the dmesg output does not show that domU recognized infiniband 
hardware at bootup.
Should I be specifying anything about infiniband in domain config file?
Any help very much appreciated,
Lamia Youseff
