Hi all,

yes that's true for example my /boot direktory in domU looks like this

blubba:/boot# ls -al /boot/
insgesamt 1260
drwxr-xr-x  2 root root    4096  6. Apr 20:25 .
drwxr-xr-x 23 root root    4096  6. Apr 20:24 ..
-rw-r--r--  1 root root   84389 13. Mär 22:20 config-2.6.26-1-xen-amd64
-rw-r--r--  1 root root 1187071 13. Mär 22:20 System.map-2.6.26-1-xen-amd64

Do you really mean DomU? The kernels are read from Dom0. If you want to read it from DomU you need pvgrub or pygrub.

I usually copy the kernel/initrd for DomUs into some other dir (f.e. /boot/domU-kernels - don't forget to change your xen-DomU.cfg) or switch to pvgrub.

If you use the same kernel/initrd-file for Dom0 and DomU, then you have to update (at least your modules) in DomU, too.
