oVirt is an open-source virtualization management platform that allows administrators to deploy, manage, and monitor multiple virtual machines across a variety of hypervisors, primarily KVM, offering features like live migration and centralized control for efficient resource utilization.
help oVirt FAQ
Is oVirt a hypervisor like KVM, or is it a management platform?
oVirt is a free, open-source management platform built around the KVM hypervisor. Its wider stack includes libvirt, Gluster, PatternFly, and Ansible. [oVirt About](https://www.ovirt.org/community/about.html)
Can oVirt move a running virtual machine to another host?
Yes. oVirt supports live migration, which moves a running VM between hosts without interrupting its service. The hosts need compatible CPU settings, shared network access, shared storage, and enough CPU and RAM. [oVirt VM Management Guide](https://www.ovirt.org/documentation/virtual_machine_management_guide/)
Can oVirt import an existing KVM or libvirt virtual machine?
Yes. The Administration Portal can import VMs through KVM via libvirt, but the source VM must be powered off during import to avoid data corruption. The destination cluster also needs compatible architecture and CPU settings. [oVirt VM Management Guide](https://www.ovirt.org/documentation/virtual_machine_management_guide/)
What does a self-hosted engine mean in oVirt?
A self-hosted engine runs the oVirt Engine itself as a virtual machine on the hosts it manages. oVirt's installation guide calls for at least two self-hosted engine nodes for high availability, with Ansible handling deployment.
