on recent Intel CPU with waitpkg feature there is a dependency of the vmx feature vmx-enable-user-wait-pause on waitpkg
however this dependebcy is wrongly expressed in Noble with the origial commit: https://github.com/qemu/qemu/commit/33cc88261c352445d31599054653d759f20531c1 this has been fixed: https://github.com/qemu/qemu/commit/2b956256439ecf02327f088a050c9c9fcca00b55 so in Noble, with a VM that has waitpkg, if it does not have vmx-enable-user-wait-pause, the feature is disabled. that makes the migration from old release (jammy in this case) impossible because jammy detects waitpkg but but not yet vmx-enable-user-wait-pause. migrations from jammy to jammy is OK migrations from noble to noble and newer (questing/resolute) is OK -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2142099 Title: migration jammy to noble fails due to missing feature : waitpkg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/2142099/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
