[libvirt-users] Oracle RAC in libvirt+KVM environment

[Timon Wang]

Thanks.

I have read the link you provide, there is another link which tells me
to pass a NPIV discovery lun as a disk, this is seen as a local direct
access disk in windows. RAC and Failure Cluster both consider this
pass through disk as local disk, not a share disk, and the setup
process failed.

Hyper-v provides a virtual Fiber Channel implementation, so I
wondering if kvm has the same solution like it.
