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
orhttp_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 andvncclient
to connect to it, then runxscreensaver-demo
and while the picture is moving do a live migration. You'll showxscreensaver
stalls for a few seconds but then keeps running — on another machine! That looks amazing, to say at least.
