How To Install mom on Fedora 36
In this tutorial we learn how to install mom in Fedora 36. mom is Dynamically manage system resources on virtualization hosts
Introduction
In this tutorial we learn how to install mom on Fedora 36.
What is mom
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.
We can use yum or dnf to install mom on Fedora 36. In this tutorial we discuss both methods but you only need to choose one of method to install mom.
Install mom on Fedora 36 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
After updating yum database, We can install mom using dnf by running the following command:
sudo dnf -y install mom
Install mom on Fedora 36 Using yum
Update yum database with yum using the following command.
sudo yum makecache --refresh
After updating yum database, We can install mom using yum by running the following command:
