# apt list --installed | grep libvirt WARNING: apt does not have a stable CLI interface.

Libvirts cached capabilities file was up to date, virt-host-validate returned "pass" for "QEMU: Checking for secure guest support" and SE guest was able to start successfully. Removed "prot-virt=1" kernel parameter and rebooted host. Libvirts cached capabilities file had been updated, virt-host-validate returned "WARN (IBM Secure Execution appears to be disabled in kernel. Add prot_virt=1 to kernel cmdline arguments)" for "QEMU: Checking for secure guest support" and as expected SE guest was NOT able to start. Added "prot_virt=1" kernel parameter and rebooted host. Libvirts cached capabilities file has been update, virt-host-validate returned "pass" for "QEMU: Checking for secure guest support" and SE guest was able to start successfully. Played around with kernel parameter values (prot_virt or prot-virt setting it to 0 or 1) a couple of times. All seems to work as expected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1874647 Title: [Ubuntu 20.04] Stale libvirt cache leads to VM startup failures To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1874647/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
