A nicer "vmadm list" for SmartOS

Screenshot:

This displays the Alias at the top left, the UUID at the top right, and the first IP address and RAM allocation on a second line. Stopped zones (if any) are displayed below the running ones.

Code follows:

#!/usr/bin/env python2.7
from subprocess import check_output


def list_vms(state):
  vlr = check_output([
    "vmadm",
    "list",
    "-p",
    "-o",
    "alias,max_physical_memory,nics.0.ip,uuid",
    "state=%s" % state
  ])

  vlr = [vm for vm in vlr.split("\n") if len(vm)]

  if len(vlr):
    print state.capitalize().center(80)
    print "=" * 80

  for vm in vlr:
    vm = vm.split(":")

    print "%s%s" % (
      vm[0],
      vm[3].rjust(80 - len(vm[0]))
    )

    print "%s%s" % (
      "IP: %s" % vm[2],
      ("Memory: %s MB" % vm[1]).rjust(80 - 4 - len(vm[2]))
    )

    print


if __name__ == "__main__":
  list_vms("running")
  list_vms("stopped")

I hope this proves helpful to someone else. Of course this requires installing Python 2.7 in the global zone where pkgin isn’t available by default, see here how to install pkgin in the global zone, after that you can simply do a pkgin in python27.
