[one-users] OpenNebula 3.2 + Xen 4.0 = headaches

[Christopher Metter]

Hi there,


I'm trying to get OpenNebula with a Xen Node working.
Configuration:
- OpenNebula 3.2 installed on Ubuntu Server 10.04 64-Bit
- Xen 4.0 installed on Debian Squeeze 64Bit
Both running nonvirtualized on seperate computers.

Xen installation is complete and running (afaik), can start a Ubuntu VMs.

I've setup OpenNebula using your documenation, but I run into problems 
when i try to complete your 'Tutorial' 
http://opennebula.org/documentation:rel3.2:vmg .
Executing 'onevm create ttylinux.one' results in "[VMM][E]: No kernel or 
bootloader defined and no default provided."
As far as I can tell this is okay and normal, Xen needs a defined 
bootloader.

So I tried following three options:
1. Setting OS = [  bootloader="/usr/lib/xen-4.0/bin/pygrub" ]   (or OS = 
[  bootloader="pygrub" ] )
which results in:
[...]

I don't know how to fix these issues. Can someone help me with this 
/these problem/s ?


Any help you can give me in this matter is greatly appreciated.
