usually it's best to manage storage in the host system, not in the
VMs.  In that case, it's just a usual Linux setup.  Once you get the
storage running in your host, KVM will take it, no matter what
technology is used underneath.

If, on the other hand, you do use Infiniband for some applications
_inside_ the VMs, then you would need to pass the PCI devices to the
VMs, a totally different issue; and one I don't know about.
