There is an apparmor deny that could be related, but the path looks just wrong.
audit: type=1400 audit(1523957176.480:37835): apparmor="DENIED" namespace="root//lxd-testkvm-bionic-tononshared_<var-lib-lxd>" pid=8721 comm="qemu-system-x86" fsuid=64055 ouid=64055 profile="libvirt-1c67131a-7177-4f49-9840-f1092310890d" denied_mask="wr" operation="open" name="/0" requested_mask="wr" Name = /0 ???? The deny is on the migration target.
