udev, SLES and Hyper-V

I got bitten by the udev GUIDs when I did the move/upgrade/move back of my on-prem blog server this morning.

 

What should have been a simple evacuation of some VMs, upgrade the host to Windows Server 2012 R2, move the old VMs back in place – turned into another episode of handcrafting grub entries and checking that everything mounted back up correctly.

 

I got bit by this before – and I need to drill into the best practices for using SLES 11/udev in a virtual environment.
