Need some help regarding CPU allocation

SolidxGaming

I am using Virtualizor on my dedicated to make some kvm virtualization vps for my mc servers. It has a e3 1245 v2 processor which has 4 cores and 8 threads. In virtualizor during vps creation, it asks me for CPU percentage for each vps and this is the help article of that. http://www.virtualizor.com/wiki/Creating_A_VPS#CPU_Parameters

but if I make a large world, than the entire node load rises up a lot and hampers other players. I did it just for testing, but imagine you are selling vps, and a guy abuse cpu on one vps, than other vps will also be affected. this is very bad. Is it virtualizor bug? Or am I doing something wrong. And I am allotting 150% CPU (that means 1.5 threads), please correct me if I am wrong, and the load rises to 4+.

Edit: 1.5 thread fully used should mean 1.5 load right?

Nope that's not a bug, that's why most (?) of providers suspend/shutdown VMs for very high CPU usage for so much time which affects other VMs drastically.

How many virtual cores do you allocate per 1 VPS? Are you sure it is a CPU problem and not IO?

Oh, so it seems it's not virtualizor fault. But before I used to use Openvz and there was a software called nodewatch maybe which did the thing. Is there anything similar in KVM?

Try CPU %: 20%

Maybe.

Actually 4c+4ht you have cpu power for ~5 threads.
