I used this: virsh list and then virsh list --all, but none
of the vms defined in my virt-manager are visible.
When running it with sudo it worked, but who wants to do that?
Then I found this link that solved my pain. Making a note here for myself as well:
$ cat ~/.config/libvirt/libvirt.conf
uri_default = "qemu:///system"
Or
$ virsh -c qemu:///system list --all
