I'd be really surprised if RHEL or any other distro would not work with a mainline 3.x kernel with a few changes or updates regarding initramfs ... for userspace we know that everything is fine, otherwise nobody could run an older distro as guest system, which works nicely as we all know (i.e. userspace can work quite well with recent kernels) the boot process, especially module loading and udev are probably the main concern, considering that some older kernels had no need/support for udev and/or required some kind of special handling, but all that can be taken care in a modern initramfs (see devtmpfs for details) you might not be able to use all new kernel features with an old userspace on the host, but that's not really relevant for Linux-VServer either, because recent enough util-vserver will do everything you need to get the guests up and running, regardless of the surrounding userspace so, if somebody creates a RHEL or whatever kvm image to experiment with, I've no problem to build an initramfs to boot into 3.0 for that just to prove that it can be done best, Herbert > Gordan
