Building Dunfell yocto image for hyper-v / virtualbox AMD64

Hi,

How do you make a yocto image for hyper-v / virtual box?

So far I can get a wic file to boot but it is the missing partitions.

I believe the uefimg image contains all the partitions? but it doesn’t boot/no bootable device detected

Everything in the local.conf is the default with the addition of configurations from the build-for-demo page alongside the mender server URL and token.
And meta-mender-core added to the yocto project, both being Dunfell.

This is just a guess, but perhaps you need to change MENDER_STORAGE_DEVICE to /dev/vda?
