I recently purchased a second server which is running an Intel processor and want to move all the VM's + Hosted Engine to this second server (INTEL_HOST). I was wondering what the proper procedure to do this would be. I have attempted a few things but nothing is successfully working. I have added and activated the INTEL_HOST through the Hosted Engine UI but since the AMD_HOST is AMD based and the second is Intel based I had to create a separate cluster (INTEL_CLUSTER). I can move all VM's to this new cluster but have not figured out how to get a Hosted Engine working on INTEL_HOST.</div><div><br></div><div>Attempting to force migration of the Hosted Engine to INTEL_CLUSTER fails with the following:</div><div>Cannot migrate VM. There is no host that satisfies current scheduling constraints. See below for details:</div><div>The host INTEL_HOST did not satisfy internal filter HA because it is not a Hosted Engine host..</div><div><br></div><div>Attempting to deploy a second hosted engine also runs into errors (hosted-engine --deploy). After downloading the answers.conf file from AMD_HOST, setup fails because of a different process type/family. I manually downloaded the answers.conf file and changed the processor type but setup validation fails because the path to the hosted engine metadata does not exist.</div><div><br></div><div>hosted-engine --deploy --config-append=answers.conf</div><div>...</div><div> [ ERROR ] Failed to execute stage 'Setup validation': failed to read metadata: [Errno 2] No such file or directory: '/rhev/data-center/mnt/<nfs_mount>/<he_uuid>/ha_agent/hosted-engine.metadata'</div><div>[ INFO ] Stage: Clean up</div><div><br></div><div>This metadata file points to /var/run/vdsm/storage/<he_uuid>/<more uuids...> but the he_uuid folder does not exist. I suspect this path doesn't exist because the storage domain is mapped for AMD_CLUSTER's hosted engine and cannot be referenced by another cluster. vdsClient does list the storage domain info though on the INTEL_HOST.</div></div></div></div></blockquote><div><br></div><div>There shouldn't be any difference in paths between amd and intel.

The next option was to just export all VM's, setup INTEL_HOST and a new hosted engine from scratch, and import all VM's, though I would prefer not to have to do this.</div><div><br></div><div>Does anyone have any recommendations on how to make this move? I would simply like to move my Ovirt installation onto the INTEL_HOST. I thought I would be able to add the second host, migrate all data over, and remove the first host, but this procedure is getting hung up on dealing with the hosted engine.</div><div><br></div><div>Thanks,</div><div>Josh</div></div></div></div>
