BZ#1405963
With this update, the vioscsi.sys file is now compatible with Microsoft Cluster Services, which enables the Windows virtio-scsi driver to support Windows Server Failover Clustering (WSFC) using shared storage. As a result, vioscsi.sys can pass all tests in the "Validate a Configuration" process.

3.4.2. Known Issues

These known issues exist in Red Hat Virtualization at this time:
BZ#1351213
In bootstrap mode, prior to having the self-hosted engine storage domain imported, the Manager tells VDSM to disconnect the iSCSI target prior to attaching the master domain. The Manager doesn't know that hosted_storage is using the same target, as it is not in the database yet. 

As a result, VDSM disconnects the target, the Manager virtual machine loses connectivity to its disk, sanlock times out, and the Manager virtual machine is restarted.

To avoid this, do not use the same ISCSI target for the master domain and the hosted_storage domain.
BZ#1343938
The Disk Alignment feature is unavailable for PPC.
