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

[Christopher Metter]

Hi there again,

I know, a long time has passed...

But I'm still having problems with my OpenNebula and my Xen Cluster.

Giovanni Toraldo's answer was some kind of a hint, and I tried several 
options for my XEN setup:
- Building XEN from source
- Applying the patch mentioned in Giovanni's Links
- Installing Packages on Ubuntu 10.04 64-Bit
- ...

But it all concluded in failed VMs.
For some moments I thought I am there, but the logs tell me some "Found 
interface tap-1-768 but domain 1 does not exist." Error.

As I've tried many options so far, but did not succeed at all, I'm 
wondering if theres some companion in misfortune out there who might 
give some advise.

Is there any up-to-date Tutorial for an OpenNebula Installation with Xen?
All up-to-date stuff I am finding is for KVM and the Xen ones are from 
another decade ;)

For those of you who have a running OpenNebula+Xen Configuration:
- What is the OS of your Xen-Hosts (Ubuntu/Debian/..?)
- Installation from Source or Package?
- What Version of Xen are you exactly running?
- Please submit a working template for ttylinux or some other 
rebuildable VM(Ubuntu/Debian..)
- Any further hinds?



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


Best regards

Christopher
