Ok, thanks @URfog that put me on the right track. My fog web server is not a storage node. I added it to the list of storage nodes with a max clients of 0 and I can boot normally now.

@Arrowhead-IT It’s definitely worked for test VM’s that are used for image testing, but it’s also a more general comment for ESXi in general. Worth checking your server guests to ensure they’re all on vmxnet3.

@fjarken said: Ah yes I have STP setup on my network, I came back to this thread again, cause I found a conflicting IP with my fog server…which I think was the root cause. A switch on my network had been configured with the same IP. I’ll be sure to start asking this… seems its a more common problem than what one would think. Gotta love happy endings.
