Public bug reported: After upgrading to the latest Ubuntu 18.04 packages I was unable to create new qcow2 disk on NFS shared disk. It worked fir years without problems.
Solution for this was change of client configuration in fstab to: 172.17.252.157:/mnt/storage/ha /mnt/storage nfs _netdev,noatime,vers=4,x-systemd.automount 0 0 I have change vers from 3 to 4 and file creation was possible again. Then another one hits me: libvirt: error : unable to set AppArmor profile 'libvirt- 93a02ea1-4ab0-4978-98fb-2cc669f9169c' for '/usr/bin/kvm-spice': No such file or directory Now, solution was to add NFS mounted directories manually to: /etc/apparmor.d/abstractions/libvirt-qemu /dev/sd* rk, /var/lib/libvirt/images/*.ign r, /mnt/storage/docker/*.ign r, This doesn't look like normal behavior to me because I didn't need all that before last update.
