nova-bhyve
An OpenStack Nova compute driver that runs instances as bhyve virtual machines on FreeBSD.
Status
Features
- Direct VM management through
bhyve/bhyvectl - Instance root disks on ZFS
- Supports booting from qcow2 and raw Glance images
- Glance images cached as zvols with zero copy root disk cloning
- VNC console integration through
nova-novncproxy - Cold attach of cinder volumes
- Cold attach of network interfaces
- Instance snapshot and upload to Glance
- Nova image cache manager support to prune cache when no longer needed
Roadmap
- Cold migration between hosts (currently only supports same-host migration i.e. instance resize)
- Support for additional ephemeral/swap disks
Limitations
- Live migration is not supported yet by bhyve, so is not implemented in this driver
Host requirements
zfs allow delegation is needed for the dataset holding images and instances.
A devfs.rules entry is needed to grant the group running Nova read/write access to the zvol device nodes.
You must configure volmode=dev on the dataset so that the host does not publish guest partition tables into its own /dev.
Configuration
Example configuration for Nova:
[DEFAULT]
compute_driver = bhyve.driver.BhyveDriver
allow_resize_to_same_host = True
[bhyve]
zfs_dataset = zroot/nova
