With this change one can get list of domains on the command line: $ virt-viewer -c qemu:///system <TAB><TAB> dom1 dom2 ... domN The list of domains is fetched using virsh, hence the dependency on libvirt-client recorded in the spec file. I think it's fair to assume that Linux hosts with virt-viewer will have virsh available too. If they don't, nothing breaks and no error message is printed. The completer script is inspired by libvirt.
