Comment 8 for bug 1751907

Just to make sure we're talking about the same thing, when I ask maas
for a machine without the 'virtual' tag, it gives me a machine with
the 'virtual' tag.

I wasn't asking for a pod machine at all - that would be filtering on
pods and I agree that would be a feature request. I was specifically
trying to get a non virtual machine, and as a side effect of having a
pod on the same MAAS, it didn't work.

I consider that a bug, but feel free to consider it a missing feature
- I don't really care about that part ;).
