Same on 4.12.2. Expect to see stats for all Vms from all projects.

Setting the Regression flag, as I believe this used to work well in 4.11.z.

From my testing, this issue doesn't present when the UI is run locally. The charts render as expected in my development environment, but fail to do so when I access the same cluster via the UI rendered by the server.
