No that should be perfectly fine and is pretty much what I do (I use the XenSource 2.6.18-xen tree though). > My major problem with 2.6.25 was that I was trying to build a > 64-bit kernel which caused the config system to disable Xen. > Quite explainable if xen is not yet available for 64-bit in the > current linux tree...
