MOM is a policy-driven tool that can be used to manage overcommitment on KVM
|
|
|
|
|
|
hosts. Using a connection to the hypervisor software (either libvirt or oVirt
|
|
|
|
|
|
vdsm), 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. If configured, MOM regularly evaluates a
|
|
|
|
|
|
user-supplied management policy using the collected data as input. 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.
