Subject: redhat: Add QEMU 9.1 compat handling to the s390x machine types
|
||
|
|
|
||
|
|
JIRA: https://issues.redhat.com/browse/RHEL-52319
|
||
|
|
|
||
|
|
Upstream changed the amount of information that is migrated for
|
||
|
|
the S390 interrupt controller (FLIC), so we have to switch on
|
||
|
|
a compatibility property for older machine types.
