The QEMU monitor is not available through libvirt or virt-manager. libvirt has various commands that let you see how much memory and other details are being used by the guest. Take a look at the 'virsh' commands: http://libvirt.org/virshcmdref.html In particular, virsh dommemstat Domain should get the information you need, for a guest called 'Domain'. http://libvirt.org/sources/virshcmdref/html/sect-dommemstat.html Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-df lists disk usage of guests without needing to install any software inside the virtual machine.
