I upgrade to CentOS6 from 5. The new (well, for me at least) 
virt-manager is much changed with respect to the one in 5. I miss cpu 
usage percentage and memory usage (both in percentage and the absolute 
amount). Is there a way the get this information quickly in an overview?

I just want to have an idea of how much memory is consumed by the 
virtual machines and if there is enough free for a new machine. This 
information and the cpu info I need to decide if a machine should be 
migrated to another host.

When I used Xen in the past, it was easy. xm list just showed a column 
with memory. Then I went over to KVM and could only use virsh list. Or 
virsh dominfo, but that is per virtual host. So since then simply 
started virt-manager.
