Oh, I've completely missed that. Sorry. What is your libvirt version?
Since v5.9.0 libvirt will autostart domains exactly once for every boot
of the host. I mean, when libvirtd is started it will check if
/var/run/libvirt/qemu/autostarted file exists and if it doesn't, it will
autostart all qemu domains with autostart enabled. If the file does
exist then no autostart is attempted.
My version show:
virsh version
Compiled against library: libvirt 4.0.0
Using library: libvirt 4.0.0
Using API: QEMU 4.0.0
Running hypervisor: QEMU 2.11.1
Compiled against library: libvirt 4.0.0
Using library: libvirt 4.0.0
Using API: QEMU 4.0.0
Running hypervisor: QEMU 2.11.1
Is it right? I thought my system is up to date.
This usually works as expected - when host boots and starts libvirtd
service all domains are autostarted. And if libvirtd is restarted
afterwards no autostart is happening. If host reboots, /var/run should
be purged and the file with it. Therefore, autostart will be run after
reboot again.
Under what connection does your domain live? qemu:///system or
qemu:///session? Because if it is the latter then this won't work -
session daemon is not started automatically. However, if you are using
socket activated system daemon, then the daemon is not started on the
boot only on its first use and therefore autostart will be delayed until
then.

I can do
virsh -c qemu:///system
and list --all shows my domains
(virsh -c qemu:///session won't do it)
So I guess under qemu:///system
