KVM Server as Firewall - how to copie this Server

[vikozo]

Hello
I have a running KVM Firewall, which in a short time should be running.
I would like to crate a copy of this KVM Server. So if I config something and it breaks I could just point the router to the other firewall and everything would be all right.

Any Idea how to copy/clone a KVM Server and save it as standby Server?

Have a nice day

Hallo,
Is this a standalone Server or is it in a cluster?
On the PVEServer are no VM ever running and never will?
