This is still using the session daemon, which only starts when you
connect to it or when you log in with the session daemon service setup
to start automatically.

There are two ways to overcome this.  One is to use the system daemon
instead (virsh -c qemu:///system) which you can also set as your default
for example by setting uri_default = "qemu:///system" in
~/.config/libvirt/libvirt.conf and there are other means as well.

If you are running a system with systemd then you can also setup
lingering for your user (loginctl enable-linger <your-user>) as that
would enable running the user services even without being logged in.
