Apart from the fact that XEN is paravirtualization technology and running a mission-critical Windows DomU is possible mostly in theory? Disclaimer: I have not touched Xen over a couple of years (when Windows guests were possible on KVM, at least in principle, and not possible on Xen). I checked the current docs out of curiousity and phrases like "PV drivers are being developed" and "you need to disable driver signature checking on (every!) reboot" [original emphasis] don't inspire much confidence. Other points Gilad made (KVM being much less intrusive and already in the vanilla kernel and provided by RedHat) are very much valid. To the OP: Xen is not for you. I have no first-hand experience (beyond a tiny bit of tinkering) with KVM. I have quite a bit of production experience with VMware. I am surprised that most of the postings focus on the VMware Server (previously known as GSX). IIRC the OP mentioned "crucial" servers but did *not* say $0 was a requirement. I'd go with ESX for mission-crtical stuff. For a serious installation I would not keep data (or system images, for that matter, but YMMV) on directly attached disks. -- Oleg Goldshmidt | p...@goldshmidt.org _______________________________________________ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
