Hi Eric, A VM with a primary disk that's a LU accessed through a vHBA works fine, however, right now the process is fairly manual. You would need to create the vHBA as described at: http://fedoraproject.org/wiki/Features/VirtStorageManagement When the host discovers the LUs, use /dev/disk/by-id/... when you assign the LU to the guest. Migration presents an additional challenge. If you want to be able to migrate the guest, the easiest thing to to is to create two WWNs and expose the LUs for the guest to both of them. You can then create the vHBA with one WWN on the source host and with the second WWN on the destination host. If you use /dev/disk/by-id/... for the path that you assign to the guest, the paths should be correct on both systems. After migration completes, the vHBA on the source host can be destroyed and used on the destination host for any subsequent migrations. Hope that helps, Dave
