Xen users - May 2010 - Problem loading Xen image

Hi all,

I''ve installed the Xen 3.1 Hypervisor on a machine that previously had
Centos4.5 (kernel 2.6.9). I''ve downloaded a Fedora 12 image from
stacklet.com and trying to create the vm, but I''m getting the following
error: 
Error: (2, ''Invalid kernel'', ''xc_dom_find_loader: no
loader found\n'')


I''m new to Xen so I''m not sure what other information would be
required to
resolve this.


Thanks in advance.

So you have Xen 3.1, installed from source, on Centos 4?

First of all, /home is generally not a good place to store xen
kernel/ramdisk/image. Also, wherever you put them, make sure xen tools
(pygrub, etc.) have access to them (i.e. not blocked by
permission/selinux).

Second, since you use PAE kernel, make sure both xen and dom0 kernel
also compiled with PAE.

Third, try changing it to your dom0 kernel, copied to the same path
(/home/dlogo/xen/images/fedora12/). If it works, then you know for
sure its kernel compatibility issue. If it doesn''t work, most likely
it''s permission problems.

Lastly, if you''re happy with Xen 3.1 (i.e. don''t need latest
version),
I''d suggest simply upgrade dom0 to latest RHEL/Centos5, which comes
with its own well-maintained, well-tested, known-to-work Xen 3.1.2+.
