But I didn’t.

After I booted 9 of the 10 devices (nr. #2 failed with a flaky DVD drive, and a possibly broken fan), I could only access them “a few times”. They behaved very erratically. A bug in the kernel? Random oopses?

It was a bit simpler than I have thought.

sudo arp -v | grep 00:01

10.0.0.43 ether 00:01:02:03:04:05 C eth0 10.0.0.45 ether 00:01:02:03:04:05 C eth0 10.0.0.40 ether 00:01:02:03:04:05 C eth0 10.0.0.46 ether 00:01:02:03:04:05 C eth0

The fix of course was really easy:

Because we don’t yet read the MAC address from the Keyvault, I just hardcoded it. My fault. Entirely.
