Hi all, In my setup of Cactus, I found Nova scheduler would place newly created instance to a compute node that is already full occupied (in terms of memory or # of virtual processors), which lead to swapping and VP overcommitting. That would cause serious performance issue on a busy environment. So I was wondering if there's some kinda mechanism to limit to resource one compute node could use, something like the 'weight' in OpenNebula.
I'm using Cactus (with GridDynamic's RHEL package), default scheduler policy, one zone only. Any suggestion? -- Regards Huang Zhiteng
