virsh:tldr:6b2ba

This command uses the virsh tool to dump the XML configuration of a virtual machine specified by ${guest_id} and save it to a file specified by ${path-to-guest-xml}.

Here's a breakdown of the command:

• virsh: This is the command line tool for managing virtual machines using libvirt, a virtualization management API.
• dumpxml: This is a subcommand of virsh that is used to retrieve the XML configuration of a virtual machine.
• ${guest_id}: This is a placeholder for the unique identifier or name of the virtual machine whose XML configuration you want to dump. You need to replace ${guest_id} with the actual guest ID or name.
• >: This is the output redirection operator in the command line. It is used to redirect the output of a command to a file.
• ${path-to-guest-xml}: This is another placeholder that indicates the path and filename where you want to save the dumped XML configuration. You need to replace ${path-to-guest-xml} with the actual file path and name.

In summary, this command retrieves the XML configuration of a virtual machine using virsh and saves it to a specified file.
