x86 images are targeted at PC type devices.

You can install an x86 image in a virtual machine. This small set of steps should assist you in setting it up for Hyper-V.

1. Download an x86 image (probably x64 if you're going this far) in the “combined-ext4.img.gz” format
2. Extract the gz so you just have the .img
3. Get a copy of qemu-img
4. qemu-img.exe convert source.img -O vhdx -o subformat=dynamic dest.vhdx

1. Memory: your choice (do not enable dynamic memory)
2. Processor: your choice, benefits above 2 may not be seen depending on workload
3. IDE Controller: Hard Drive: Select the vhdx created before
4. Network Adapter: How you configure these is up to you, but you should create at least 2 (one for WAN one for LAN). If you only create 1, it will be assigned to LAN. The last port created will always be assigned to WAN (if > 1).
