Hi,=0A I gave up trying to restore a backup of my former hosted engine=
, I never managed to get engine and nodes communicate again and I need t=
o go on. So I installed a new engine (let's try a dedicated one this t=
ime) and imported the storage domains successfully. After attaching and=
activating them, it seems to be ok and the first VMs I imported are now=
running fine. So I just have to redefine logical networks and configu=
re them on the hosts, and it is ok ? Maybe final step will be turning=
dedicated engine to hosted, I don't know yet. Regards =0A=0A Le 18-=
