Hypervisor configuration basics

The node where the nova-compute service is installed and operates on the same node that runs all of the virtual machines. This is referred to as the compute node in this guide.

By default, the selected hypervisor is KVM. To change to another hypervisor, change the virt_type option in the [libvirt] section of nova.conf and restart the nova-compute service.

Here are the general nova.conf options that are used to configure the compute node's hypervisor: nova-hypervisor

Specific options for particular hypervisors can be found in the following sections.
