    LGTM Tested it, works great (even without single change to agent.properties). It will
reserve 1GB by default.

> 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,
