Hi.

We are running oVirt 4.3.4 with each of the hosts configured to use local storage.

When I attempt to export a large virtual machine as an OVA the process begins but fails about half an hour later.

On the oVirt Events page the following entries appear:

Starting to export Vm Jessica as a Virtual Appliance
Failed to export Vm Jessica as a Virtual Appliance to path /storage/Jessica.ova on Host Trueblood

When I log onto the host Trueblood I see that a file called Jessica.ova.tmp has been created.

The engine.log file contains the following errors:

Any suggestions/help on solving this would be much appreciated.
