[one-users] Force VMs from specific template to deploy on single host only

[Hamada, Ondrej]

Hi,
I'm trying to figure out how to force the virtual machines based on one template to deploy always together on a single node. A scenario:

I have four nodes. I need to deploy five VMs related to each other. I want all the five to be deployed on the same host. Little bit later I need to deploy another set of five VMs. I want all the five of them to be deployed on a single node, but it should be different node then the preceding set of five VMs was deployed on.

Speaking in terms of available scheduler policies is combination of packing and stripping. First use the stripping - find the node with highest count of available resources and then packing - deploy the VMs on same node.

Is this even possible in OpenNebula?



Thank you in advance,

Ondra
