I have SLES 11 SP4 Xen server with two paravirtualized VMs (PVMs) with SLE-10-x86_64-SP3 and OES v.2.0.2.
Multipath is configured for 2 LAN interfaces (different subnets) connected to LIO ISCSI target.
features “2 queue_if_no_path no_partitions”
path_selector “round-robin 0”
For HVMs I had to add there this line
features "2 queue_if_no_path no_partitions"
otherwise the HVMs didn’t start.
If I keep this line for PVMs, I get libvirt error and the PVMs don’t start.
If I comment this line, the PVMs start and are waiting for root partition to appear with no success.
