It's not a matter of Xen not supporting Windows. Nothing needs to be changed in Xen to make Windows work. It is either Windows not supporting Xen or Intel hardware not supporting full virtualization which would allow operating systems to be virtualized without any modification to the OS. But the next generation of Intel and AMD will correct a deficiency in the cpu design so full virtualization will be possible. At that point I don't know how Windows could possibly know it is being virtualized. As for comparisons: The Linux kernel is going with Xen so I think we will see support for UML go away eventually. Xen is definitely better performance-wise. UML is also a Linux only thing. Windows will never work under UML. Xen virtualizes hardware interfaces in such a way that a fault in a driver won't necessarily take down the whole system so I think things are actually safer when running under Xen. As for UI, they are both controlled via command-line but Xen allows you to do a lot of things on the fly that UML will not such as increasing/decreasing available memory or even migrating the running OS from one system to another with only a few milliseconds of downtime. There is really no comparison IMHO. - -- Tracy R Reed http://ultraviolet.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFC0AvZ9PIYKZYVAq0RAkyfAJ9vKJ6mAJ7sIAL4Mfr/TKrj/bUl6QCeOT3i Sx5/TgTkdewTzeY9uzpgPC8= =RtVy -----END PGP SIGNATURE----- -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
