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 Nova HyperV.
Libvirt¶
Information on the libvirt-based drivers kvm
and qemu
can be found in
Libvirt - Nova Virtualisation Driver.
VMware¶
Information on the VMware-based driver vmware
can be found in
VMware - Nova Virtualisation Driver.
XenServer¶
Information on the XenServer-based driver xenapi
can be found in
XenServer - Nova Virtualisation Driver.
Bare Metal¶
Information on using Nova with Ironic to deploy compute instances to bare metal can be found in Ironic - Bare Metal provisioning.
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
.
