Automated VM Rebalance

Hello Everyone,

I was wondering if there was a way to have Cloudstack do an automatic rebalance of VMs?

As an example, when we perform maintenance on a node, we will migrate all the VMs from that node to another node, as well all know. Then, after maintenance is done, we would want to rebalance the nodes again. Is this possible? Would it be a cron job kicking off an API call, etc?

Any help is always appreciated.

Hi Marty,

You're looking for CloudStack DRS which was introduced last year in 4.19: https://www.shapeblue.com/cloudstack-drs/
