Public bug reported: [Impact]
Some times libvirt fails to start a vm with the following error : libvirt: error : unable to set AppArmor profile 'libvirt-b05b297f-952f-42d6-b04e-f9a13767db54' for '/usr/bin/kvm-spice': No such file or directory This happens because for some reason file /etc/apparmor.d/libvirt/libvirt-<vm-uuid> has 0 size. Although, we do not now why the above file gets truncated and therefore we do not know the root cause, I open this bug to come up with a way to mitigate the issue. E.g. when libvirt sees that this file is 0-size to delete it and create it again. [Test case] To reproduce this behaviour, create a vm and stop it, note the uuid. Then : ## touch /etc/apparmor.d/libvirt/libvirt-<vm-uuid> # touch /etc/apparmor.d/libvirt/libvirt-b05b297f-952f-42d6-b04e-f9a13767db54 # ls -la libvirt-b05b297f-952f-42d6-b04e-f9a13767db54 -rw-r--r-- 1 root root 0 May 6 18:46 libvirt-b05b297f-952f-42d6-b04e-f9a13767db54 Try to start the vm, it will fail with : libvirt: error : unable to set AppArmor profile 'libvirt-b05b297f-952f-42d6-b04e-f9a13767db54' for '/usr/bin/kvm-spice': No such file or directory To be able to start the vm again just delete the libvirt-<vm-uuid> file.
