- Last updated date: 23 October 2012
This feature covers changes to ovirt-engine, vdsm, and mom to enable a memory ballooning MOM policy at the host or cluster level. For users desiring a high level of VM density even with a risk of degraded performance, an aggressive management policy including memory ballooning is needed. Implementation of this feature can be broken down into the following sub-tasks
- MOM: Multiple policies support
- MOM: Per-VM attributes
- MOM: auto-balloon policy
- vdsm: API for setting/getting/clearing MOM policies
- engine: host policy management
- engine: Policy selection UI
Benefit to oVirt
oVirt will gain the ability to achieve higher VM densities and more efficient use of host memory resources. This feature also serves as the foundation for a more sophisticated SLA framework that will be developed over time.
