My p2v was sticking at 2% and eventually failing. Nothing was apparently wrong and a p2v worked yesterday to the same cluster.
Looking at the logs I ran across a message that led me to this forum post. This was our problem too. We had two NICs in a team – one was ok, but the other one had a duplex mismatch. A quick change of active NICs and the p2v worked just fine.
Thanks Stridar for following up to your post with the resolution.
