------- Comment From [email protected] 2023-02-09 10:10 EDT------- Please note: In addition to this kernel part, there is also a QEMU and a libvirt part required to implement the feature "KVM: Improve memory reclaiming for z15 Secure Execution guests".
The two other parts (QEMU and libvirt) which will not be ready in time for 23.04, are handled in the following bugs / LP entries: Bug 201597 - [23.10 FEAT] KVM: Improve memory reclaiming for z15 Secure Execution guests - qemu part Bug 201598 - [23.10 FEAT] KVM: Improve memory reclaiming for z15 Secure Execution guests - libvirt part -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1933180 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.
