Comment 9 for bug 1577809

I just ran into this:

[stack@rhlab ~]$ virsh list --all
error: failed to connect to the hypervisor
error: no valid connection
error: Cannot create user runtime directory '/run/user/1001/libvirt': Permission denied

For me the root cause seemed to be related somehow to me destroying / undefining the domains manually (where as I should have used --teardown).
