I'm using OpenVZ to virtualise a MPP cluster and its great.|
However I can;t get native infiniband user space protocols to work inside my containers.
The IPoIB works fine but I need OpenMPI to access the lower level protocols on the VM
The OFED.org ste indicates that virtualisation is supported on the card, so it *SHOULD* be possible under OpenVZ.
A overview of IB virtualisation is available here: www.mellanox.com/pdf/whitepapers/WP_Virtualize_with_IB.pdf
To try and hack a test VM into compliance I have even tried linking the proc and sys filesystems to the host (yuk), but I still cant get basic driver recognition in VM user space.
All drivers are installed on the VM but modprobe can't find some of them - no idea why.
I am using the Melanox version of OFED 220.127.116.11.0.0.2 on Centos 5.7 (host and VM).
Is there any plan to implement a module equivalent of Xen-IB module?
I am desperate to solve this, if it cant be done, I will have to use a different virtualisation system.
Thanks in advance,
