I have a test environment that use to work but no longer does. My
laptop is Fedora36 (libvirt version 8.1.0.2) while the VMs it spawns are
RHEL7 (max libvirt version is 4.5.0). The source of my problem
seems to be that RHEL7 libvirt needs rw socket /var/run/libvirt/libvirt-sock
which no longer exists in fedora36.  

The following is successful from RHEL7 VM to laptop:
virsh -d0 --connect 'qemu+ssh://192.168.120.1/system?socket=/var/run/libvirt/libvirt-sock-ro' domstate beaker-test-vm1.beaker

If I change the action from domstate to start, it fails on 
error: Failed to start domain beaker-test-vm1.beaker
error: operation forbidden: read only access prevents virDomainCreate
which made me realize ro stands for read-only; however, there is no
libvirt-sock. I tried some of the other socket files without success.
Is there a work-around?
