Is anyone using Xen ?Is anyone using Xen ?Posted Jul 21, 2005 3:25 UTC (Thu) by Blaisorblade (guest, #25465)In reply to: Is anyone using Xen ? by copsewood Parent article: Kernel Summit 2005: Virtualization
> Xen promises much better performance, particularly when new silicon proposed by Intel and AMD becomes available, with specific support for virtualisation.
This is well-known, but I'd like to point out that even UML is going to take advantage of that new silicon, and even a lot more than Xen I think. There's a lot of ongoing work at Intel on this, and you can read about this on the 2005 Linux Symposium Proceedings, in the talk by Jeff Dike.

Is anyone using Xen ? Posted Jul 29, 2005 14:59 UTC (Fri) by markwilliamson (guest, #26407) [Link] VT / Pacifica combined with Xen is an interesting topic.Vanilla Xen gives you near native performance in virtual machine *already* - hardware extensions aren't going to provide any immediate improvements for OSes that run natively on Xen (Linux, BSD, etc) because you can't really do better than the unvirtualised performance. The real benefit of hardware support for virtualisation in Xen's case is that it will enable *unported* operating systems to run, and achieve reasonable performance. The primary benefit will be the ability to run Windows. You'll also be able to run old, unported versions of Linux on Xen in order to migrate old servers completely onto Xen with no configuration changes.
