Sorry for the delay, I finally found some time to get back to this. This is still reproducible on current Ubuntu 17.10:
virsh define m.xml qemu-img create -f qcow2 /var/lib/libvirt/images/subVmTest1-2.img 128M virsh start subVmTest1 dmesg shows: [ 319.220193] audit: type=1400 audit(1520004938.754:40): apparmor="DENIED" operation="open" profile="libvirt-269b6725-e6fb-4242 -a83a-3ad286dd5efb" name="/etc/gss/mech.d/" pid=5930 comm="qemu- system-x86" requested_mask="r" denied_mask="r" fsuid=64055 ouid=0 m.xml is attached. It's lightly edited to remove some external file and device references, to be more or less self-contained (except for the image created above; but that can be empty - it doesn't matter what's actually running in the VM). ** Attachment added: "reproducing machine XML" https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1696471/+attachment/5067161/+files/m.xml ** Changed in: libvirt (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1696471 Title: AppArmor denies access to /etc/gss/mech.d/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1696471/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
