I had some problems to install a XenServer 6.2 on my LSI 3ware 9750 Raid Controller, as there is no native support for the controller in the shipped kernel. Unfortunately my efforts (btw: thanks for stackoverflow – i love it!) to solve the problem by my self got a little bit stucked, because of the complexity.
Afterwards I definitely should had contact LSI earlier, as they came up with the solution within 24 hours…
