Containers density
Why OpenVZ containers density is so much better that that of Virtual Machines (Xen, VMware, KVM). - automatic elastic behaviour and no memory reservation -- real advantage - explain that even best hypervisors (ESX) achieve only 2x memory overcommit. Actually 50% of it are due to page sharing, and 50% due to balloon. - Virtuozzo templates and file sharing add even more savings - what happens when CT is above it's limit - what happens when node RAM is exhausted - plots and examples. Kir had http_load plot in the past. We will have LAMP results as well.
