Xen 3.2 is in the final stages of preparation. We (Xen upstream) are planning to provide binary packages for Centos 5.1, amongs others. I've merged the patches and so on from xen-3.0.3-41.centos5.i386.rpm with a recent xen-unstable RC tip (16701:8922a1469284). With a bit of effort I have managed to get a set of packages which appear to be able to work at least in my simple `does this function at all' test. I'm mentioning it here so that you can have a look at what I've done and comment on it. We'll probably be making official upstream rpms very soon after the Xen 3.2 release, which we hope will be early next week. Please send me feedback either here on-list or privately. Most of the useful patches from 3.0.3-41.centos5 have been incorporated upstream so I just deleted those from my srpm. There were also a few changes which I have just dropped. In particular, the RHEL5 package (and thus the Centos one too) is a bizarre frankenxen containing a forward port of the 3.0 dom0 userland tools to the Xen 3.1 hypervisor. In my package I have included the hypervisor in the xen-*.rpm rather than making a kernel package too. This is more in line with practice upstream; dom0 kernel compatibility between the 3.1 and 3.2 hypervisors is good and the new hypervisor seems to work for me with the Centos 5.1 2.6.18-53.el5xen kernel. You can find the actual files here: http://www.chiark.greenend.org.uk/~ijackson/xen-3.2-package-previews/centos5.1/ These packages should not be used for production - they're previews and I may have made elementary packaging mistakes. Xen 3.2 is still unreleased and in need of more testing. Please check the SHA256's before installing them: 8d1ab89c420559aac762e7b526b57f80434d45006c162713bd2120b43868a385 xen-3.1.9-0xs.centos5.i386.rpm 380062047a72308996a568f177c60125582acb48c2df2c0811f025542fa24367 xen-3.1.9-0xs.centos5.src.rpm 437b363c3f45a8e74db395468b127245fd775ddb9bd8b5e85f1a4d8ec7809e04 xen-debuginfo-3.1.9-0xs.centos5.i386.rpm 2b81624aa303828b06bda11201a6f2eaf923c384830c8cff5d3f53a22ebaf393 xen-devel-3.1.9-0xs.centos5.i386.rpm dfef6550f4d693c999923ba9b2d5ead7b8bbeca3bed0cbdc0835ca516d773ddc xen-libs-3.1.9-0xs.centos5.i386.rpm Regards, Ian.
