I am a graduation student at the University of West-Flanders in Belgium and I am researching the possibilities of XenMotion in Citrix XenServer. Now I am trying to get XenMotion working from an Intel Xeon X5365 (Clovertown 3GHz) to an Intel Xeon X5470 (Harpertown 3.33 GHz).
I am guessing that maybe the SSE4.1 capability of the Harpertown is what's causing the failure. (It won't be the clockspeed because migrating from X5365 to E5345 (Clovertown 2.33 GHz) works perfectly)
My collegue is working on ESX, trying out VMotion, and he has the capability of masking cpu flags from withing ESX.
Now I am wondering if it would be possible to hide flags in the proc filesystem or with an instruction at boottime maybe?
