Xen project Mailing List

Hello,

I am facing some problem in booting up a DomU in Xen 3.2 (Installed on top of a FC8-64bit).

I installed FC8 without virtualization and on top of that installed Xen 3.2 (compiled from source). I used "make world" and "make install" for my compilation.

After this my Dom0 boots up fine. But when I try to boot a domU using the same (dom 0)kernel (with the file system and swap image being Fedora 64 images obtained from Jailtime.org), the boot process continues for some time and then stops. I am including below the entire boot messages obtained on the console.
(The same file system and swap image worked properly with a Xen 3.1 Dom0 kernel).

So can any one tell me whats going wrong? Is some thing wrong with my compiled kernel? Did I miss some configuration due to "make world"?

Please reply. If some other information is needed I can provide that. But this is a bit urgent and I will really appreciate any help.

If any one was able to install a domU properly on a FC8 + Xen 3.2 configuration (without any external tools like virt-manager/virt-install) please let me know the procedure.

Regards
Dushmanta
