  • Thread-topic: IB devices visible on RHEL5 Guest OS

I am running the Xen kernel and installed RHEL5 64bit guest OS. I have access to the ethernet devices i.e. eth0 and eth1 from the virtual machine (guest OS), but how can get access to the IB HCA (Infiniband network card, ib0) on my VM?

Here's my ethernet bridge config, can I do the same thing with IB? I haven't had any luck b/c the MAC address in 20 bytes instead of 6.   Has anyone tried this before?
[root@svbu-qa1950-3 ~]# ifconfig ib1
