Description Liran Rotenberg 2019-02-28 14:35:24 UTC 
Description of problem:
After making an OVA file using RHEV, trying to import it fails with engine error:
Error parsing OVF due to Error loading ovf, message Content is not allowed in prolog.

This error is shown when trying to import using REST API. Using the WEB UI the window stuck on "loading".

Version-Release number of selected component (if applicable):
ovirt-engine-4.3.1.1-0.1.el7.noarch
vdsm-4.30.9-1.el7ev.x86_64
qemu-kvm-rhev-2.12.0-21.el7.x86_64
libvirt-4.5.0-10.el7_6.4.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Create a VM.
2. Export the VM as OVA.
3. Import the OVA made in step 2.

Actual results:
Using REST API - getting an error in the engine, WEB UI window is keep showing as loading.

Expected results:
REST API - Import the OVA successfully.
WEB UI - show the VM in the given path, letting the user to import it.

Additional info:
The immediate difference I saw in the OVA logs is that the XML is now starting with a quote: '<?xml version="1.0" encoding="UTF-8"? .......</ovf:Envelope>' 
while before(working) was without it: <?xml version="1.0" encoding="UTF-8"? .......</ovf:Envelope>
