Administrators can manage MAAS resource pools to group machines in sensible ways. All MAAS installations have a resource pool named “default,” to which MAAS automatically adds new machines.

Add a resource pool

To add a resource pool to MAAS:

  • In the MAAS 3.4 UI, choose Organisation > Pools > Add pool; enter Name and Description; select Save pool.

  • With the UI in all other versions of MAAS, choose Resource > Add pool; enter Name and Description; select Add pool.

  • Via the MAAS CLI, use the following command:

    maas $PROFILE resource-pools create name=$NAME description="$DESCRIPTION"

Delete a resource pool

If you delete a resource pool, all machines that belong to that resource pool will return to the default pool. There is no confirmation dialogue; pools are deleted immediately. To delete a resource pool:

  • In the MAAS 3.4 UI, choose Organisation > Pools > trash can > Delete.

  • With the UI in all other versions of MAAS, choose Resource > (trash can) > Delete.

  • Via the MAAS CLI, use the following command:

    maas $PROFILE resource-pool delete $RESOURCE_POOL_ID

Add a machine to a pool

To add a machine to a resource pool:

  • In the MAAS 3.4 UI, choose Machines > (machine) > Categorise > Set pool > Select pool > Resource pool > Set pool.

  • With the UI in all other versions of MAAS, choose Machines > (machine) > Configuration (resource pool) > Save changes.

  • Via the MAAS CLI, use the following command:

    maas $PROFILE machine update $SYSTEM_ID pool=$POOL_NAME

Remove a machine from a pool

To remove a machine from a resource pool:

  • In the MAAS 3.4 UI, choose Machines > (machine) > Categorise > Set pool > Select pool > Resource pool >“default” > Set pool.

  • With the UI in all other versions of MAAS, choose Machines > (machine) > Configuration > “default” > Save changes.

  • Via the MAAS CLI, use the following command:

    maas $PROFILE machine update $SYSTEM_ID pool="default"

Add a VM host to a pool

To add a VM host to a resource pool:

  • In the MAAS 3.4 UI, choose KVM > LXD > (VM host) > KVM host settings > Resource pool > Save changes.

With the UI in all other versions of MAAS, you can add a VM host to a resource pool when you create a new VM host, or you can edit the VM host’s configuration:
