Virtual disks on block-based SRs (e.g. FC, iSCSI) have an optional I/O priority Quality of Service (QoS) setting. This setting can be applied to existing virtual disks using the xe CLI.
Note: Bare in mind that QoS setting are applied to virtual disks accessing the LUN from the same host. QoS is not applied across hosts in the pool!
