I have encountered an issue after migrating virtual machines to a new host. It happens whether the VM has been moved with live migration or though a shutdown, export, import process.
The hosts are both 2012 R2 Datacenter. The virtual machines are Generation 2 and also have 2012 R2 Datacenter. All the systems where installed with the April ISO. The only difference between the hosts is that one only has no other updates. The other has
all recommended and optional updates as off 2014-10-10.
Once the machine has migrated to the updated host the next time it attempts to boot up (after a restart, ect.) it will fail with one of these two messages.
This happens whether the virtual machine has updates or is a fresh install from the April ISO. Once the machine is migrated back to the host that does not have any updates it will boot back up without any issues.
Notes:
The virtual machines where created on the host without any updates.
When creating a new virtual machine on the host with updates the 2012 R2 ISO bluescreens.
I setup another host machine without updates, tested migration to it and then ran updates. Same issue occurs.
I have tried boot with and without secure boot enabled also tries it with drive signature enforcement disabled. No change either.
This does not happen with generation 1 machines.
What I am trying to figure out is, if it truly is an update issue which update might it be so that it can be avoided? It would also be interesting to figure out if there is a workaround to get affect virtual machines to boot back up.
Let me know what your ideas are or if there are any other tests you would like me to provide.
