In the virt-manager GUI's main view there is a sorted list of VMs. Each has its VM name written in bold. Typically the VM name is the short hostname. What would be really helpful would be support for a comment field which allows to give a little info about the host. Example: *hostname* (mail server) Status *hostname2* (web server, SELinux exceptions) Status So a free text comment line would be presented in normal font weight after the bold hostname. I could even imaging swapping the status and the comment.
Libvirt has a new 'title' attribute that might help here: http://libvirt.org/git/?p=libvirt.git;a=commit;h=b79ba8382e2205c416d7c4836ac9ee08c72e2c56
