[PVE-User] VM's load balance...

Seem to be a bit old (2008) and not maintained.

I really think it should be easy to code it for proxmox, maybe extending pvestatd daemon.
analyse vm cpu stats, do the algorithm to find if we need to migrate a vm, then execute qm migrate


But I don't have too much time to work on this for the moment.

yeah... I saw it last night...

Hi, We have already all the stats of cpu,memory,.. for hosts and guest. 

I think the main part is to define the balancing algorithm. (I had found an interesting paper about this last year, need to find it). 


Also proxmox don't have a "master" server in a cluster, so each node should do the balancing, 

don't known if they need to communicate... (to avoid loop like node1 balance vm to node2, then node2 balance vm to node1,....)

Thanks for your answer... 

I'm here imagining some scripts that checking memory load or processor load and perform qm migrate to other host through the cluster... 
May need some programming effort, but is possible... or not??

I think this will require client tools installed on the KVM's like 
vmware-tools in vmware to be able to do something like that. I have no 
knowledge of whether something like that exists for qemu.
