FreeBSD in CML
Instructions for running a basic FreeBSD node in Cisco Modeling Lab.
Deployable image
A pre-built FreeBSD image is available here.
In Linux the above image can be decomressed with:
xz --decompress FreeBSD-14.1-STABLE-amd64-BASIC-CLOUDINIT.ufs.qcow2.xz
From there the qcow2 file can be imported into CML.
By default the FreeBSD image is configured to use DHCP. It also supports a native serial console which is ideal for CML.
FreeBSD node definition
A FreeBSD node definition is include in this directory.
Limitations and future work
The FreeBSD 14.1 "Basic Cloud-init" image comes with "nuage-init" rather than "cloud-init". Nuage-init does not support all options that are available in cloud-init. A base configuration is provided in this node definition.
If the CML node has Internet connectivity it is possible to use the package manager to install cloud-init. This will allow you to use cloud-init on subsequent boots. This approach may have limited utility if you are using Terraform to provision the CML node.
Nuage-init: MAC address required
If you are attempting to use Nuage-init in order to set an IP address please have a look at the source code.
Nuage-init will explicitly check to see that there is an ethernets
section with a match subsection. The only working match clause is the
macaddress clause. If you do not explicitly state the MAC address of
your NIC it will not be able to set an IP address. Both DHCP and IPv6 are
supported.
The following user-data example will set the IP address of the NIC with
the specified MAC address to 192.0.2.10/24.
network:
version: 2
ethernets:
id0:
match:
macaddress: 'aa:bb:cc:00:11:22'
addresses:
- 192.0.2.10/24
