My ideas: z/VM

z/VM should support reflective_relay and cisco ACI

This capability would solve real-world networking issues for zVM. The current OSA implementation has no way to associate mac addresses with vlan tags, so we can't use cisco ACI + bridge domains to segment traffic into multiple vlans on a single su...

Increase the SET LKFAC limit above 250 users for use by guest operating systems (TPF)

Increase the MPLF virtual DASD locking limit above the 250 user limit using SET LKFAC. In 1998 the LKFAC limit was increased from 64 users to 250 users (VM61408). One of the reasons for this increase was to allow more TPF guests to run LKFAC to su...

Improve Initial RACF installation procedures

While performing an initial installation of z/VM V7.4 with RACF, the IBMUSER id is used for initial logon. If the CP Directory has an ACIGROUP entry for IBMUSER that is not SYS1, the initial logon fails after password change, since IBMUSER's ACIGR...

Enable Ansible integration with z/VM

Ansible Automation is an extremely popular tool that is available on many platforms (including zOS) except for zVM. While providing native SSH access to zVM may be unrealistic I believe that leveraging a Linux VM with SMCLI to communicate to SMAPI...

Support for 32 TB of real memory per LPAR via feature statement

Would like to be able to have fewer, larger LPARs. If the reconfigurable memory is the limiting factor, then for cases where reconfigurable/dynamic memory is not needed, it should be possible to include a config file statement that disables/bypass...

SSHD Support for zVM OS

SSHD support directly in VM would allow for modern tooling to connect and utilise the platform. Version control of config files via GIT for example.

Enable flashcopy Command for ESE Volumes

With the new DS8A00 and FCM4 it is necessary to define all Volumes as type ESE (Extended Space Efficent). But we found that the normal flshcopy command under z/VM doesn't either work with ESE-Volumes. You must establish, copy and withdrawn the Fla...

DFSMS/VM interaction with DRFAMILY on TS7700

Please consider adding the ability to interact with DRFAMILY on TS7700 from a zVM LPAR (DFSMS/VM).

LFAREA 2GB pages not supported

z/OS client running under z/VM requires to use large pages memory to run their DB2, Openshift, Splunk and other consumers applications. as an example; z/OS client is coded this way : LFAREA=(1M=16896,2G=(16,10))
