Is it possible to convert a Virtualbox image to Hyper-V? Preferably without having to startup the virtualbox image.
This has been discussed on our sister site superuser.com before - take a look HERE.
Having problems with the VirtualBox built-in converter (Hyper-V would not open the disks), I had better success with Disk2vhd from Microsoft SysInternals - just run the EXE inside the VM you want to migrate. Detailed instructions at https://hyperv.veeam.com/blog/how-to-convert-physical-machine-hyper-v-virtual-machine-disk2vhd/
- You do need to run the VM in VirtualBox to create the image
- You get a VSS backup, so after migration the VM didn't get a clean shutdown.
- It's a small utility - no install required
- It handles multiple spindles
- You get a .vhdx for each spindle
- It handles image creation on UNC network path
- It's blissfully unaware of snapshots - no need to consolidate or clone first.
Once you have the images, attach them to your Hyper-V VM & start it. The first took a minute, while Windows got used to it's new hardware.
That depends a lot on what's in the image.
As a disclaimer, I know nothing about what VirtualBox tends to install in a guest OS image. If any of that stuff crashes when VirtualBox isn't present, there's nothing I know of that will help you.
But if your guest OS is Windows Vista or later, you can do quite a bit of servicing off-line, just by mounting the disk image and manipulating it via the OPK tools. You can install drivers and other components, including the Hyper-V integration components.
