xen and fedora

[Lefu Ntho]

Hi guys,
apologies for posting on xen mailing list earlier,

I have fc14 running kernel-2.6.35.13-91.fc14.x86_64.
I did
$ yum install xen

I would like to compile xend modules with this,

I did steps according to
http://wiki.xensource.com/xenwiki/Fedora13Xen4Tutorial

$ make -j4 bzImage && make -j4 modules
$ make modules_install
$ depmod 2.6.32.40 ( its here where I later run into problems as I do not
have the right kernel to use, maybe?)
$ cp -a arch/x86/boot/bzImage /boot/vmlinuz-2.6.32.40
$ cp -a System.map /boot/System.map-2.6.32.40
$ cp -a .config /boot/config-2.6.32.40
$ cd /boot/
$ dracut initramfs-2.6.35.13-91.fc14.x86_64.img 2.6.32.40
Will not override existing initramfs
(/boot/initramfs-2.6.35.13-91.fc14.x86_64.img) without --force
$rpm -qa | grep xen
xen-runtime-4.0.1-7.fc14.x86_64
xen-licenses-4.0.1-7.fc14.x86_64
xen-hypervisor-4.0.1-7.fc14.x86_64
xen-libs-4.0.1-7.fc14.x86_64
$

is there something I am missing?
Please point me to the right direction. I will do the rest

Thank you in advance

I replied on that mailing list too, but perhaps my email didn't make it to you.

This is the problem. Notice that the two version numbers don't match.
You're trying to update a ramdisk for a 2.6.35 kernel, but you're
telling it to use 2.6.32 modules. That's why it's giving you the error
below.

hi Mike,
indeed it got to me, I think what I am trying to find out is steps to take
before I execute dracut. because the tutorial states for fc13, I think guys
have already done this on fc14. I attempted to fetch and install myoung
kernel but it fails as its build for earlier kernel version than the one I
have.
Thanks

You won't be able to run xen with your stock Fedora 14 kernel. You'll
have to replace it completely with a xen-capable kernel, like Jeremy's
2.6.32 kernel that you build yourself, or one of the ones that myoung
built for Fedora 12.

It should work if you yum install the specific kernel version. Or you can 
download it and run rpm -ivh --oldpackage .

Though a stock Fedora 16 kernel will work (with xen 4.1 and xl).

Sorry, does this mean an F16 kernel will work as a Dom0 with no issues? 
Or do I have my wires crossed here! :)

Well, you have to set up grub yourself to get it to boot dom0, and you 
would be using qemu instead of blkback so disk access is slow, but xen 
network support is in the kernel, and thus you can indeed use it as a 
Dom0. I don't tend to use the more advanced xen features, so I am not sure 
which are supported and which aren't.
