I installed Virtual Machine Manager (VMM) 2016 to migrate some VMWare VMs (ESXi 4.1 VMs nonetheless) to Hyper-V. However, every time I went into the Convert Virtual Machine wizard in VMM I was greeted with a blank screen that looked like this:
No matter what I did (refreshing libraries, restarting VMM, etc) it wouldn’t populate with VMs to convert.
It then occurred to me that since a requirement of the migration is that the VMs have to be powered off, that maybe they wouldn’t show up until they were turned off. So I created a test VM and left it turned off and sure enough:
I would have much preferred that all eligible VMs showed up in the list and you were just unable to select them instead.
