[RHEV] virt-v2v migration of a windows 2008 R2 guest from KVM fails.

Issue

• Using the following command to migrate a Windows 2008 R2 guest from RHEL 6 KVM host to RHEV 3.0 export domain:

# virt-v2v -i libvirtxml -o rhev -os rhevm.example.com:/export --network rhevm vmname.xml 2>&1 | tee virt-v2v.log

• Looking at the v2v verbose logs:
