I have used this successfully with non locked memory. I wonder about comment #22 - would you mind restarting libvirtd and report "dpkg -l libvirt-daemon-system" instead of only "virsh version"?
The remaining issue (comment #20) you see with prlimit is an issue in apparmor. TL;DR it is allowed in the apparmor profile but failing due to apparmor. This already affected passthrough hotplug in the past and is known to IBM. See bug 1679704 I'd not mark this one here as a dup, as I fixed the initially reported problem. Instead I'd ask you to chime in on the referred bug to raise its priority now that we know more things being affected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1755153 Title: [Ubuntu 18.04] Memory hotplug fails with error 'virSecurityManagerSetMemoryLabel' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1755153/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
