What happen to an oversold OpenVZ host that runs out of ram/disk space?
I am wondering what happen to an oversold OpenVZ host that runs out of ram/disk space?
1)Lets say that OpenVZ is oversold on ram, and (in some freak event) more than the physical ram is requested by the vps's (but all are within their guaranteed limits) Clearly there is not enough real ram to supply each vps. What happens then? Is some type of disk swap used?
2) Similarly, what happens when each vps request too much disk space (within their plan) but more than is physically on the hard drive?
I am not knocking overselling ( I know it has its purpose), I am just wondering what happens in such scenarios?

people come to this forum, open a "HOST" SCAM, NO REPLY, NO EMAILS ANSWERED, NO REFUND GIVEN threads and then after 3-20 pages, everyone goes to bed.
1) Swapping occurs and then processes are killed and in extreme cases the node might crash.
2) The VPSs and the node get an "out of disk space" error and in extreme cases the node might crash.
No RAM & SWAP left? The OOM Killer comes out from under the bed!
For no disk space on the container it just shows stuff like "no space on drive" when you try to create a file, even though df -h shows free space. If the node is rebooted ("SolusVM is down, quick - reboot it!") then any containers might fail to start.
Deadpool.
In short: the shit goes down heavy.
