Integrity VM allows Virtual FileDVDs to be shared by guests.
With HP Serviceguard, you can share Virtual Disks. Other types of
storage devices are not supported for sharing and cannot be allocated
to multiple guests. Be careful when you set a virtual device to sharable
using the hpvmdevmgmt command. Incorrectly marking
a virtual device as sharable can lead to device conflicts and data
corruption if multiple guests access it concurrently. In particular,
attached devices (tape, burner, or changer) should not be made sharable.
