Description

On SLES, if Xen is installed, during the inventory creation, the VM will be checked by the command xenstore. Nevertheless, the path is wrong and the inventory will not be valid and will never be accepted in Rudder.

I suppose that we have here two problems:
- To retrieve information about the VMs on SLES 11 we should use /usr/bin/xenstore instead of /bin/xenstore and on SLES 10 by the use of /usr/sbin/xm list (not really equivalent)
- No be able to retrieve information should not prevent from completing the inventory otherwise it causes machines to never be accepted

I've tried on Rudder agent 2.6.9 but it could be the same on 2.4.12.

Erratum: On SLES 10 SP3, the package xen-tools-3.2.3_17040_16-0.4.9 contains the same binary: /usr/bin/xenstore-read

Another rectification:
It depends of the tools used.
- On guest (domU), the package xen-tools-domU is installed with the binary /bin/xenstore-read
- On Host (dom0), the package xen-tools is installed with the binary /usr/bin/xenstore-read

This is an easy fix, just a separate classes case for SLES_10 and/or SuSE. I'm on it.

Nicolas, if you know the fix, it would be so much quicker for you just to provide a pull request.
