zVM support dynamic activation of non subchannel set 0 devices

A VM LPAR supports one CSS but it can be 0,1,2,3 but only supports one SS via HCD - 0. Add support for additional SS

Apply dynamically HW CRYPTO definitions to z/VM

Changes in z System LPAR activation profile regarding CRYPTO definitions can not be made dynamically available to a LPAR running z/VM. Today it is necessary to shutdown the z/VM and perform a LPAR deactivate followed by LPAR activation. This is an...

z/VM support of SuperPAV

DS8880 (DS8884 and DS8886) and z/OS supports SuperPAV. z/VM does not support SuperPAV. More Alias required per LCU. Support of SuperPAV will relieve UCB/address constraint.

z/VM support of thin provisioned ECKD Volumes | HCP9050W CP-OWNED volume is on a Space-Efficient DASD.

z/VM does not support IPL from Thin thin provisioned ECKD Volumes. Preconfigured DS8880 (with thin provisioned) can't be used for z/VM system disks. Preconfigured HDS VSP G1000 (with thin provisioned) works fine for z/VM system disks (HDS VSP G100...

Support VS-CODE for editing native (Rexx, HLASM, etc.) CMS files

Currently VS CODE supports editing z/OS datasets on a workstation via the z/OSMF facility. CMS developers would benefit from having the same capabilities for editing CMS files using VS-CODE and its toolsets.
