Hello guys,

I have installed a SLES10 SP1 with xen on a computer, and tried to make my domU 
working with infiniband with the "Mellanox Drivers for Novell-XEN" (I got it 
from this link : http://www.mellanox.com/products/xen.php)

The problem is that the virtualized ib seems to don't exist. In fact i have a 
file ifcfg-ib0 in /etc/sysconfig/network/, modules for infiniband seem to be 
running, but ifconfig ib0 returns "ib0: error fetching interface information: 
Device not found"
I have a MT25204 adapter (on mellanox website it's written that it only works 
on MT25208, but the only difference I saw between the one and my one is the 
number of ports.)

Here is a problem at the domU's boot sequence :

Loading HCA driver and Access Layer: [ OK ]
Setting up InfiniBand network interfaces:
Setting up service network . . . [ done ]
Setting up network interfaces:
lo IP address: done
No configuration found for eth1 unused
Waiting for mandatory devices: eth-id-00:16:3e:50:05:b8 __NSC__
20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 0
eth-id-00:16:3e:50:05:b8 No interface found failed
cat: /sys/class/net/ib0/type: No such file or directory
Interface ib0 is not available failed
Setting up service network . . . . . . . . . . . . . . failed

Here is lsmod | grep ib :

ib_ipoib 78296 0
ib_cm 39208 1 ib_ipoib
ipv6 281856 15 ib_ipoib
ib_uverbs 43696 0
ib_umad 20656 0
ib_mthca 323624 0
ib_sa 30560 3 ib_ipoib,ib_cm,ib_mthca
ib_mad 42148 4 ib_cm,ib_umad,ib_mthca,ib_sa
ib_core 65424 7 ib_ipoib,ib_cm,ib_uverbs,ib_umad,ib_mthca,ib_sa,ib_mad

Any suggestions ?

Best Regards
Renaud Durand
