Please note that this is a development version of nova. Many features are not available. Currently nova works on FreeBSD 11 and supports QEMU and Xen. Common issues: - Security groups are not implemented - ARP spoofing, DHCP isolation protection are not implemented - Nova services work from the root user - No IPv6 support QEMU issues: - Need to enable serialconsole (TCP) - Need to disable online CPU tracking - Cannot mount cinder volumes Xen issues: - Live snapshots don't work - No support for cinder volume hot-plugging - XENBUS delay (5 min) when using qemu driver and COW images - Some Linux images cannot be booted For further FreeBSD specific notes please refer to port's pkg-message.
