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.
