Problem creating a snapshot "No root disk defined."

Hi there.

I've been having some trouble the past few days and I can't seem to find a solution, maybe somebody here can help me.

Last week we had a problem with our datacenter and we had to shut it all down.

When it came back on, our VIO infrastructure began having some problems.

I've managed to solve most of them, except for this one that happens when we try to create a snapshot of an instance.

When you try to do that, the image goes from "Queued" to "Saving" and then "Killed".

When I look into nova-compute.log, I see this error:

"

2016-11-08 21:59:30.949 9924 TRACE oslo_messaging.rpc.dispatcher NoRootDiskDefined: No root disk defined."

I'm using VIO 2.0 with vSphere 5.5

I've looked everywhere, but can't seem to find someone else with this problem.
