I/O fencing support for virtual-to-virtual clustering
Disk-based SCSI-3 I/O fencing is supported for VCS clusters across VM guests on different physical machines. In case of VM as iSCSI initiator, virtual machines can be on same or different physical machines. The support matrix table lists the SCSI-3 fencing support for various Linux virtualization technologies.
