[ovirt-users] oVirt OVA Export -> oVirt OVA Import failure

I carried out the following procedure: 1. Exported a VM as an OVA to a 4.3 environment host. 2. SCP'd the file to a host on a 4.5.0.3 environment. 3. Selected Import VM - Virtual Appliance (OVA) - selected the Host and path - clicked Load but no VMs are listed. This process previously worked in 4.4 Is this a known bug? Cannot upgrade to 4.5.1 until our internal mirrors have been updated. Regards Simon...
