Many company?s work with xen and the performance is better than KVM. Here some benchmarks with Citrix XenServer 5.0 vs KVM with linux and windows guests on an IBM x3400 server: HDD: XEN | KVM Write: 110 MB/s | 60 MB/s Read: 130 MB/s | 80 MB/s Network Performance: (download an 4 GB iso image from apache webserver) XEN | KVM download Speed: 105 MB/s | 50 MB/s xen is using the full 1000 mbit network.. great performance! On our IBM servers Xen is still faster than KVM. -----Original Message----- From: linux-kernel-owner@vger.kernel.org [mailto:linux-kernel-owner@vger.kernel.org] On Behalf Of Andrew Morton Sent: Saturday, February 28, 2009 6:28 AM To: Jeremy Fitzhardinge Cc: H.

And what other patches can we expect to see to complete the xen dom0 support? and.. I hate to be the one to say it, but we should sit down and work out whether it is justifiable to merge any of this into Linux. I think it's still the case that the Xen technology is the "old" way and that the world is moving off in the "new" direction, KVM? In three years time, will we regret having merged this? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
