Nova - Compute Service
Nova is a core service in OpenStack, and provides compute services. Typically this is via Virtual Machines (VMs), but may also be via bare metal servers if Nova is coupled with Ironic.
Nova is enabled by default, but may be disabled by setting
enable_nova to no in
globals.yml.
Virtualisation Drivers
The virtualisation driver may be selected via
nova_compute_virt_type in globals.yml.
Supported options are qemu, kvm,
vmware, and xenapi. The default is
kvm.
HyperV
Information on using Nova with HyperV can be found in hyperv-guide.
Libvirt
Information on the libvirt-based drivers kvm and
qemu can be found in libvirt-guide.
VMware
Information on the VMware-based driver vmware can be
found in vmware-guide.
XenServer
Information on the XenServer-based driver xenapi can be
found in xenserver-guide.
Bare Metal
Information on using Nova with Ironic to deploy compute instances to
bare metal can be found in ../bare-metal/ironic-guide.
Fake Driver
The fake driver can be used for testing Nova's scaling properties
without requiring access to a large amount of hardware resources. It is
covered in nova-fake-driver.
Consoles
The console driver may be selected via nova_console in
globals.yml. Valid options are none,
novnc, spice, or rdp.
Additionally, serial console support can be enabled by setting
enable_nova_serialconsole_proxy to yes.
Cells
Information on using Nova Cells V2 to scale out can be found in nova-cells-guide.
