Thanks Khanh,
I see the potential issue with using threads. Thanks for pointing out.
On using
containers, that sounds like a cool configuration

I can run multiple compute service in same hosts without containers.
Containers give you a nice isolation and another way to try a more
realistic scenario, but my initial goal now is to be able to simulate many

Using compute inside LXC, I created 100 computes per physical host. Here
is what I did, it's very simple:
- Creating a LXC with logical volume
- Installing a fake nova-compute inside

Thanks Sergey,
Will look into this, but still have the same question, would introducing
containers increase my footprint per fake compute service?
Yes. There is more then one processes

Thanks John,
I also think it is a good idea to test the algorithm

As a heads up, the overheads of DB calls turned out to dwarf any

Hello all,
I have been trying some new ideas on scheduler and I think I'm reaching a
resource issue. I'm running 6 compute service right on my 4 CPU 4 Gig VM, and I
started to get some memory allocation issues. Keystone and Nova are already
complaining there is not enough memory. The obvious
