> We have several KVM nodes running Cloudstack 4.4.2. Sometimes an instance with X amount of RAM provisioned will be started on a host that has X+a small amount of RAM free. The kernel OOM killer will eventually kill off the instance. Has anyone else seen this behavior, is there a way to reserve RAM for use by the host instead of by Cloudstack? Looking at the numbers in the database and the logs, Cloudstack is trying to use 100% of the RAM on the host.
> Any thoughts would be appreciated.
> Thank you,
