Just hit this issue, you need to mask the libvirtd services as per the
docs and in addition to that you need to instruct libvirt (the client
bit) to use the legacy/monolithic approach.
Add the following to /etc/libvirt/libvirt.conf :
remote_mode="legacy"

Hello everyone,
I'm in a situation where I need to migrate my infrastructure to new
servers
as soon as possible. I have installed CS 4.18 management and agent on
the
same node. I have gone through the installation guide and configured
libvirtd based on documentation. However, I am unable to add a KVM
host.
Below is the error I am getting in the agent.log file. Please note that
I
have set all required parameters in libvirt config file.

It says that agent is unable to connect libvirt.
Please advise.
Thanks.
