Re: Can RHEL7 VM run remote commands to Fedora36 host?

I have a Fedora36 laptop which hosts VMs with RHEL7 using libvirt.
One of
the RHEL7 VMs, runs remote commands (as root) to 'start' another VM by
way of my laptop. In other words, the following command is run:
virsh --connect 'qemu+ssh://192.168.120.1/system' start
beaker-test-vm1.beaker
If I run non-remote version of the command on the laptop, it is successful.
For example,
virsh --connect qemu:///system start beaker-test-vm1.beaker <-- Successful
on laptop.
If I do a query like the following *(notice socket use)*, it is successful.
virsh -d0 --connect
'qemu+ssh://192.168.120.1/system?*socket*=/var/run/libvirt/libvirt-sock-ro'
domstate beaker-test-vm1.beaker
Without socket, I get the following error:
*error: failed to connect to the hypervisor*
*error: End of file while reading data: Ncat: No such file or directory.:
Input/output error*
This is peculiar, it suggests that
/var/run/libvirt/libvirt-sock
does not exist, while /var/run/libvirt/libvirt-sock-ro does exist.
This ought to be an impossible situation in general. As Erik says,
In Fedora 36 we have the moduler daemons, so these two sockets are
provided by 'virtproxyd.socket' and 'virtproxyd-ro.socket' unit
files, so make sure both of those are running.
With regards,
Daniel
