Hello, I''ve recently set up a CentOS 6.0 guest, using qemu (http://www.virtuatopia.com/index.php/Using_QEMU_Disk_Images_for_Xen_DomainU_Systems) and I would like to install a domU kernel inside the virtual machine, but I don''t find anything with yum while in the CentOS 5.3 yes. Actually, CentOS 5.3 has the following kernel in the /boot directory (we are still talking about domUs - my dom0 is Gentoo Linux): vmlinuz-2.6.18-274.7.1.el5xen. But I''m not convinced that it is a well configured domU kernel. Anyway: is there some kernel image to be installed as domU kernel inside the virtual machine? -- Flavio _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

That being said, in the past pv_ops kernel performs not as well xenified kernel, not to mention some missing features (e.g. memory/cpu hotplug). There''s also many improvement in latest vanilla kernel compared to 2.6.32 (which is what rhel/centos is based on). So if you/re REALLY concerned about optimizing or a particular feature, then you might want to compile your own kernel based on latest vanilla linux 3.x (based on pv_ops) or suse''s kernel (which is the most recent xenified kernel available), then compare the results. Generally I''d say don''t bother though, just stick with the bundled kernel. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
