I've got some machines that use KVM as virtualization platform. I monitor then using munin, but I was not able to find munin plugin that shows proper usage of memory by virtual machines. I've found this one http://munin-monitoring.org/browser/munin-contrib/plugins/virtualization..., but it shows memory declared for VM in config file (maximum memory value for VM to be honest). So this one is not good if you want to see realtime memory usage.

Almost everyone knows ssh port forward (-L/-R) or dynamic port forward (-D) features. They are very useful. For example when connecting to the internet using hotspot or other free access point it's very good idea to use ssh dynamic port forward. Doing so prevents other users from beeing able to see your traffic.
