Testing qemu-2.10-rc3 shows issues like:
qemu-system-aarch64: -drive file=/home/ubuntu/vm-start-stop/vms/
7936-0_CODE.fd,if=pflash,format=raw,unit=1: Failed to unlock byte 100
There is an apparmor deny due to qemu now locking those files:
apparmor="DENIED" operation="file_lock" [...]
name="/home/ubuntu/vm-start-stop/vms/7936-0_CODE.fd"
name="/var/lib/uvtool/libvirt/images/kvmguest-artful-normal.qcow"
[...] comm="qemu-system-aarch64" requested_mask="k" denied_mask="k"
The profile needs to allow locking for loader and nvram files via
the locking (k) rule.
