Been having an issue with Generation 2 VM templates where we get error 13206 ~25-50% of the VMs we deploy. I haven't been able to find anything consistent between the failures; they happen seemingly randomly on all hosts on all of our clusters. If I do a repair and choose to ignore the error, then boot the VM, I get to a sysprepped image screen. I've tried setting the primary boot device to the hard drive via both Hyper-V -> create template (after setting is changed) as well as a powershell script which sets the hard drive as the primary boot device. I have the check box ticked in "Contains Operating system for the virtual machine" for the only hard drive in the template.
I saw that there was a fix in rollup update 8 for VMM, but we're on update rollup 9 and still having the issue. Again, this works a little over 50% of the time, which is really strange to me. Anyone have any ideas?
