Description: MOM is a policy-driven tool that can be used to manage
overcommitment on KVM hosts. Using libvirt, MOM keeps track of active virtual
machines on a host. At a regular collection interval, data is gathered about
the host and guests. Data can come from multiple sources (eg. the /proc
interface, libvirt API calls, a client program connected to a guest, etc). Once
collected, the data is organized for use by the policy evaluation engine. When
started, MOM accepts a user-supplied overcommitment policy. This policy is
regularly evaluated using the latest collected data. In response to certain
conditions, the policy may trigger reconfiguration of the system’s
overcommitment mechanisms. Currently MOM supports control of memory ballooning
and KSM but the architecture is designed to accommodate new mechanisms such as
cgroups.
