Labelling devices for MAAS

Tagging the untaggable: labelling MAAS devices

Tagging in MAAS isn't just a matter of slapdash annotations; it's the art of precise identification for network configurations and hardware attributes. Utilising XPath functions such as contains, starts-with, and ends-with, you can streamline your MAAS setup. Check out these real-world examples that unleash the power of tagging. For an even deeper dive, explore more examples here↗.

Hypervisors: more than just a tag

Identify and categorise machines primed for hypervisor roles. This example scours for machines with at least 40 cores and 256 GB of RAM. The cherry on top? It filters machines with specific CPU features for both Intel and AMD.

And for the CLI magicians:

maas ${MAAS_PROFILE} tags create name=hypervisor \


Isolate UEFI-enabled KVM virtual machines running on AMD servers. Streamline your hardware filtering for a smoother operation.


And the CLI version:

maas ${MAAS_PROFILE} tags create \

Finding the fast: NVME servers

Instantly tag servers sporting NVME controllers for high-speed data storage.
