Assigning EP11 adapters as dedicated adapters to z/VM guests

On a z/VM® guest, you can authorize the user to define virtual cryptographic facilities and provide the guest access to the AP queues on the PCI cryptographic cards. You achieve this with the help of the CRYPTO directory statement using the DOMAIN and APDEDicated operands.

The DOMAIN operand specifies up to 16 domains the virtual machine may use. The APDEDicated operand specifies up to 64 APs the virtual machine may use for dedicated access to the Adjunct Processor (AP) cryptographic facility. You can specify as many CRYPTO statements as you need to assign domains or APs to the virtual machine.

You can use the z/VM CP command QUERY CRYPto DOMains to request the display of the status of the cryptographic hardware and of installed AP domains.
