My machine has PAE and xen with PAE.

I got the domU kernel and ramdisk from one of the fedora mirror from under the xen directory.  From the xend-debug.log it seems you may be right, these may not be PAE kernels.

example site :
ftp://mirror.eas.muohio.edu/fedora/linux/core/5/i386/os/images/xen/

 The errors in the debug file
xend-debug.log
ERROR: Unrecognized image format
ERROR: Error constructing guest OS
ERROR: Unrecognized image format
ERROR: Error constructing guest OS

1. how do I determine, if the kernel is PAE enabled or not.
a. when the system is running
b. when I just have the kernel files as in this case ?

I tried the kernel from /boot/vmlinuz-2.6-xen  (as this is supposed to work with domU and Dom0 both right ?)  I used the old initrd.
The error 22, Invalid argument is gone...and the domU starts  but it  crashes. (probably because of the mismatched initrd ?)

2. Where do I get PAE enabled Xen kernels where I can possibly kick of installation similar to bare metal ?
 
When I tried the following...
http://www.xensource.com/download/dl_303guest_rhel4.html

#rpm -i kernel-xenU-2.6.9-42.0.2.EL.xs148.i686.rpm
error: Failed dependencies:
        kernel < 2.6.13 conflicts with kudzu-1.2.34.3-1.i386
        kernel < 2.6.12 conflicts with initscripts-8.31.5-1.i386
        kernel < 2.6.15 conflicts with hal-0.5.7.1-2.fc5.i386

#uname -a
Linux test 2.6.16.29-xen #4 SMP Sun Oct 15 13:20:46 BST 2006 i686 athlon i386 GNU/Linux

What are my options ? Any pointers ?

Thanks
/Jd

This typically means the kernel being used for the guest is incompatible
with the hypervisor or Dom0 kernel. Common causes being PAE vs non-PAE
mismatch, or wrong archtecture, or using a baremetal kernel. The xend.log
or xend-debug.log may give you further details on the precise error.
