HyperSwap support is enhanced to allow RESERVE processing. When a system runs a  request to swap to secondary devices that are managed by HyperSwap, z/OS detects when  RESERVEs are held and ensures that the devices that are swapped also hold the RESERVE.  This enhancement is provided with collaboration from z/OS, GDPS HyperSwap, and CSM  HyperSwap. IBM z14 supports z/VM 7.1 and z/VM 6.4. z/VM is moving to continuous delivery model. For  more information, see this web page. z/VM 7.1 can be installed directly on IBM z14. z/VM V7R1 includes the following new  features: z/VM 7.1 includes SPEs shipped for z/VM 6.4, including Virtual Switch Enhanced Load  Balancing, DS8K z-Thin Provisioning, and Encrypted Paging. z/VM V6.4 can be installed directly on a z14 server with an image that is obtained from IBM  after August 25, 2017. The PTF for APAR VM65942 must be applied immediately after  installing z/VM V6.4 and before configuring any part of the new z/VM system.
