So I got this error after finishing a “migrate to production” operation on a Veeam restore of a VM to a Hyper-V host.
I attempted to attach the HDD manually, but it said error applying, cannot change disk since a disk merging is pending.
I can’t figure out WTF, there’s nothing going on here, I think it may need to be deleted and another restore operation done and leave the VM on the whole time.. I don’t get why this happens…
What the heck.. so I simply removed the HDD from the VM, then attach the full vhd and it just worked… ok dokie then.
So there you have it, if you see this error, after doing a Veeam restore guess you just have to manually remove the bad vhx file, and attach the base proper on, then the VM boots no problem.
