Hello,
I will do some tests with your image file.
thank you for the time you spent doing it
EDIT : All is working with your files.
In case someone has a problem using it here is what I had to do :
To use the image I had to add a new network adapter (a second one) and then the DS assistant was able to find it (as the first adaptater is in another subnet than mine), after I had to put a fixed IP address in the first adapter (in my network subnet) and finally I was able to remove the second one and enable DHCP (or not if I don't want to use it).
Unfortunately I have not been able to upgrade the image to 4.2
Video station is not working too (I have to restart the syno and by SSH I have to remove manually the directory Videostation in /volume1/@app... ) but it is a problem with xpenology as it is not working with virtual box. Perhaps there is a license or something like that in the syno.
Thanks again for the time you spent doing it.
Marc
