Yeah, AppArmor is enabled, but I put everything (that I could find) into
complain mode:
$ sudo apparmor_status
apparmor module is loaded.
12 profiles are loaded.
3 profiles are in enforce mode.
lxc-container-default
lxc-container-default-with-mounting
lxc-container-default-with-nesting
9 profiles are in complain mode.
/sbin/dhclient
/usr/bin/lxc-start
/usr/lib/NetworkManager/nm-dhcp-client.action
/usr/lib/connman/scripts/dhclient-script
/usr/lib/libvirt/virt-aa-helper
/usr/sbin/libvirtd
/usr/sbin/ntpd
/usr/sbin/rsyslogd
/usr/sbin/tcpdump
3 processes have profiles defined.
0 processes are in enforce mode.
2 processes are in complain mode.
/usr/sbin/libvirtd (30419)
/usr/sbin/ntpd (3418)
1 processes are unconfined but have a profile defined.
/usr/sbin/rsyslogd (626)
And still get issues. From libvirtd.log:

Thanks in advance for any help, Daniel!
Cheers,

Your config looks fine here.

Do you have AppArmour enabled on the machine. That seems like the
most likely thing that would result in libvirt getting that permission
error.
