Re: [Xen-users] using infiniband with xen

[Steven Timm <timm@xxxxxxxx>]

I have gotten as far as booting the dom0 kernel
2.6.18-164.11.1.el5xen that comes with redhat/centos
and verifying that in dom0 I can see and talk to the infiniband
card. next step is to try to do pci-passthrough to a domU.

As far as passthrough to multiple domU it is supposed to depend
on what hardware version of the infiniband card you have. I
am going out for bid for the latest version from mellanox, (connectx) 
which is supposed to support multiple virtual channels under 
virtualization,
right now vmware and soon also xen.  We are still early in the process.
I think the kind we have in our test machine, infiniscale, will work
with at most one domU at a time but I haven't even got that far yet.
