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.

LVM is one of the greatest things in linux. So much powerful, elastic and smooth approach to block devices.
You can use it almost everywhere.
