Title:
[23.04 FEAT] KVM: Improve memory reclaiming for z15 Secure Execution
guests
Status in Ubuntu on IBM z Systems:
Fix Committed
Status in linux package in Ubuntu:
Fix Committed
Bug description:
Currently, Secure Execution guest memory needs to be exported or destroyed,
when a secure guest is rebooted or shut down. On the z15 this currently happens
in a serialized manner, which takes long and also causes the host system to
become unresponsive for extended periods, if very large guests are terminated.
Changes to the KVM memory management will be required to improve the
scalability.
Value: Scalability improvement
