Does someone have a step by step tutorial to upgrade Xen to 4.0.1 with the last kernel on CentOS 5.5 please ?

mkinitrd -f /boot/initrd.img-2.6.32   2.6.32

But I have some errors about "No module xxx found for kernel 2.6.32.21, aborting."
I spent this step with : --builtin="ehci-hcd" --builtin="ohci-hcd" --builtin="uhci-hcd" --builtin="sata_nv" --builtin="usb-storage"

After I modified my grub.con but my server doesn't boot...

The default config for newer kernels might not be compatible with RHEL/Centos 5.5. One thing that I can think of right away is CONFIG_SYSFS_DEPRECATED.

You can try to rebuild my kernel SRPM (xenified kernel, not pv_ops) on an x86_64 box. It was tested for Xen 4.0, but might work on Xen 4.0.1 as well. See http://lists.xensource.com/archives/html/xen-users/2010-07/msg00452.html for details, and possibly http://wiki.centos.org/HowTos/RebuildSRPM on how to rebuild SRPM (if you don't know how).

Or you could try customizing the config your downloaded pv_ops kernel (not so easy for first-time users).

Or you can simply use latest xen 3.4.x RPM from Gitco (http://www.gitco.de/repo/), which works well with Centos' kernel-xen. It does not have the latest features (like blktap2), but should be good enough for normal uses.

Or, as Boris suggested, use a different Linux distro as dom0.
