Medium to large scale enterprises who need to manage large numbers of virtual machines and physical hosts need a system that scales to their usage. oVirt is designed to scale from a small number of virtual machines and hosts to thousands of virtual machines and hosts. There are three different types of users in the enterprise:
Hardware Administrators
Rack physical hosts and provision them with the oVirt managed node image
Create Virtual Pools for teams and assign hosts and storage to teams of users
Group hosts and storage in physical networks
Connect network attached storage (iSCSI, NFS)
Manage top-level user group membership
View usage and loading of resources, prepare hosts for downtime by migrating VMs
Team administrators
Manage user quotas, permissions, and subgroups for team hardware
Monitor physical hosts for resource issues, bottlenecks
Maintain available team VM install images/appliances
Define SLA for team hardware, in terms of: CPU availability; memory usage; network bandwidth
oVirt Users
Connect to VMs from the browser interface with a console plug-in
Create, destroy, pause, resume, save, restore VMs on a team hardware collection
Configure VMs as virtual clusters
View current and historic performance information for VMs to determine SLA needs
