Hi. I am Using MAAS 1.9.3 on Ubuntu 14.04[trusty]. One of my MAAS client node Often facing power error while enlisting. I used DELL PowerEdge R610. Power type is IPMI. Power driver as LAN_2_0[IPMI 2.0]. Client node PXE booted under MAAS to enlist itself in MAAS UI. But it was giving Power Error.

I followed http://www.ubuntu.com/download/cloud/install-openstack-with-autopilot. I want to deploy OpenStack using Autopilot on top of Ubuntu 14.04.
