[Xen-users] new kernel on Fedora 10 domU

[Bojana Petrovic <bojanap@xxxxxxxxx>]

Hi, 
I
installed Fedora 10 as domU on CentOS 5.3. I need new 2.6.25.14
kernel under domU (in order to patch it for MPLS protocol). I
followed advice on
http://wiki.xensource.com/xenwiki/Kernel.org_Linux_on_Xen, and
compiled kernel with XEN options enabled under domU. I got all
relevant packages in /boot and /lib/modules, but when I try to boot
virtual machine I got this error:

Error starting domain:
virDomainCreate() failed POST operation failed: (xend.err "Error
creating domain: (2, 'Invalid kernel', 'xc_dom_find_loader: no loader
found\\n')")

Here is my grub under
domU:

#boot=/dev/xvda
default=1
timeout=0
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
hiddenmenu
title

root=UUID=d3721a3f-a574-40f4-94c4-9273923d5471 rhgb quiet
   
initrd /boot/initrd-2.6.25.14.img

Here is
configuration file for  VM:

name = "masterf10big-1"
uuid
= "4d1e3338-4392-7ea3-e128-57ae8727e96b"
kernel =
"/boot/vmlinuz-2.6.25.14"
ramdisk =
"/boot/initrd-2.6.25.14.img"
#kernel =
"/boot/vmlinuz-2.6.27.5-117.fc10.i686.PAE"
#ramdisk =
"/boot/initrd-2.6.27.5-117.fc10.i686.PAE.img"
maxmem =
256
memory = 256
vcpus = 1
#bootloader =
"/usr/bin/pygrub"
>>>vfb = [
"type=vnc,vncunused=1" ]
disk = [
"tap:aio:/var/lib/xen/images/masterf10big-1.img,xvda,w"
]
vif = [ "mac=00:16:3e:4e:b9:40,bridge=virbr0" ]
extra
= "console=hvc0" 


If I try to compile kernel
under dom0, I do not have in initrd xen-blkfront module.
I tried
to compile this kernel under Fedora 8 domU, as well, but when I try
to boot new kernel it alway says:
no xenblk module
found!
According to new framework xenblk is replaced with
xen-blkfront modules, then, why does he ask for that one? I
understand that Fedora 8 domU uses 2.6.21.xen kernel which belong to
old framework, but anyway how can I install mainline kernel on
it?

Please, I would really appriciate any help,  I'm
really stuck up with this, for very long time, I do not know what
else to do?
