Hi,


1. Please check whether you have downloaded the CA certificate in your browser (This can be found when accessing your engine -> Downloads -> CA Certificate.
2. Please ensure you are not trying to upload the image via a WIFI connection (If you are you this will cause the operation to pause and you will need to resume it mulitple times)
3. Try to Resume the operation by highlighting the paused operation and from the menu select to resume it.

If all these don't help please file a bug in bugzilla and provide the engine.log (/var/log/ovirt-engine/engine.log on your engine and the vdsm.log on your vdsm host /var/log/vdsm/vdsm.log)


Regards,


Kevin
