Subject: [PATCH] v2v: vdsm: add --vdsm-fixed-ovf option

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

Add option for -o vdsm that enables output of the modified OVF. oVirt

engine should already be able to consume the OVF, but let's not take any

chances and enable it only by command line argument. It can be made

default later when it receives proper testing.
