We use KVM running on a Debian host, with CentOS guests. Storage is zoned from our DDN Infiniband array to the host and then passed through to the guests. We would like to zone it directly to the guests SRIOV IB HCA, but srp seems to be a bit of dead code tree. We had to do a bit of work to get it working with Debian and haven’t as yet spent the time on getting it going with CentOS.
We also run Spectrum Archive on the guest with tape drives and libraries zoned to the guest’s PCIe HBAs which are passed through from the host. We are working towards going production with this setup. Xen was a bit a failure for us so we switched to KVM.

I’m curious how you manage disks? Do you use RDM’s? Does this even make sense to do? If you have a 2-3 node cluster how do you share the disks across? Do you have VM’s with their own VMDK’s (if not RDM) in each node or is there some way to share access to the same VMDK’s? What are the advantages doing this other than existing HW use? Seems to me for a lab environment or very small nonperformance focused implementation this may be a viable option.
