Yes, I see. I just need to 'wave through' the kernel bit. But the feature will not be added to the release notes in 23.04, that will be done if all requests are included (so probably with 23.10 then). -- 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.
