Hi, I'm used to have nested hypervisors for test/devel pourposes. The missing feature when using nested hypervisors is the Power Management device, keeping my env. useless to test HA, Cluster Policy with PM control and so on. This week I had contact with the Minyard's set of patches for qemu, currently in review, adding an ipmi device to qemu. Here a post with my first experiments: http://apahim.livejournal.com/2395.html Hope you guys enjoy. Feel free to comment or suggest improvements. Best, -- apahim
