RH-Commit: [4/5] f5236c8041bfcb63df4046f7bb0a12c1fa90062d (thuth/qemu-kvm-cs9)

JIRA: https://issues.redhat.com/browse/RHEL-39898
|
||
|
|
|
||
|
|
When RHEL 10.0 gets released, the z14 will be the oldest mainframe
|
||
|
|
that is still officially supported by IBM, see:
|
||
|
|
https://www.ibm.com/support/pages/ibm-mainframe-life-cycle-history
|
||
|
|
|
||
|
|
Now each IBM Z machine can "emulate" the previous two CPU types in
|
||
|
|
hardware for virtual guests, so we should still allow the z12 and
|
||
|
|
z13 in our qemu-kvm builds, too. But everything that is older than
|
||
|
|
the z12 can be disabled now.
