Comment 5 for bug 1331214

I would say maas should use wsman instead - Intel has deprecated the SOAP API's used by amttool for quite a while according to the linked articles above.
My quick tests showed that the attached wsman script controlled the machines with v7, v8, and v9 ok.
v4 did not work (note however that the BIOS is extremely downlevel on that machine; I'm trying to update it today)
Perhaps the best way to deal with it is to add a "wsman" entry to the MAAS power control and default to that for AMT boxes - if one of these real old boxes shows up the user can switch to the AMT selection.
