Under pods read you are able to see cores, ram, storage available, but I believe it is useful to also show the networks, or more specifically, the subnets available on each of the hosts. To create a VM:
maas admin vm-host compose 30 cores=8 memory=16384 'storage=mylabel:60,mylabel:10,' interfaces='eno1:subnet_cidr=192.168.0.0/16;eno2:subnet_cidr=10.245.125.0/24'
as that is required for networking the VM’s underneath it. Instead of finding the host system_id, the querying the networks available there, it would be useful to show it all in one pane of glass under the pods read command.
