<div><span style="font-family: arial, helvetica,sans-serif; font-size: 10pt; color: #000000;">Hi,<br /></span></div>
<div> </div>
<div><span style="font-family: arial, helvetica,sans-serif; font-size: 10pt; color: #000000;">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 to go on.</span></div>
<div> </div>
<div><span style="font-family: arial, helvetica,sans-serif; font-size: 10pt; color: #000000;">So I installed a new engine (let's try a dedicated one this time) and imported the storage domains successfully.</span></div>
<div>After attaching and activating them, it seems to be ok and the first VMs I imported are now running fine.</div>
<div> </div>
<div><span style="font-family: arial, helvetica,sans-serif; font-size: 10pt; color: #000000;">So I just have to redefine logical networks and configure them on the hosts, and it is ok ?</span></div>
<div> </div>
<div><span style="font-family: arial, helvetica,sans-serif; font-size: 10pt; color: #000000;">Maybe final step will be turning dedicated engine to hosted, I don't know yet.</span></div>
<div> </div>
<div><span style="font-family: arial, helvetica,sans-serif; font-size: 10pt; color: #000000;">Regards</span></div>

Try first on a test setup, as always<br /> 2. Make sure to _not_ import the hosted-storage domain, the one used to<br /> host the hosted-engine VM.<br /> 3. So: setup a new hosted-engine system, then import your _other_ storage<br /> domains. Ideally make sure the old hosted storage is not accessible to<br /> the new system, so that the new engine does not try to import it accidentally.<br /> 4. If you do try to import, for testing, the old hosted-storage, would be<br /> interesting if you share the results...<br /><br /> Best regards,<br /> -- <br /> Didi</blockquote>
