Demo scripts which can be used to show advantages of OpenVZ:
- Full VE lifecycle (create, set ip, start, add user, enter, exec, show ps -axf output inside VE), stop, destroy). It should take two minutes ("compare that to a time you need to deploy a new (non-virtual) server!")
- Massive VE creation. Create/start 50 or 100 VEs in a shell loop. Shows fast deployment and high density.
- Use VEs from prev. item -- load those by ab or http_load -- shows that many VE are working quite fine, with low response time etc.
- If you have two boxes, do vzmigrate --online from one box to another. You can use, say, xvnc in a VE and vncclient to connect to it, then run xscreensaver-demo and while the picture is moving do a live migration. You'll show xscreensaver stalls for a few seconds but then keeps running -- on another machine! That looks amazing, to say at least.
