Convert Proxmox .raw to HyperV .vhdx

Show raw device names

zfs list 
#example output may look something like this
rpool/data/vm-100-disk-1

Export to file

dd if=/dev/zvol/rpool/data/vm-100-disk-1 of=/file.raw

Convert to HyperV

qemu-img convert -f raw /file.raw -O vhdx -o subformat=dynamic /file.vhdx

Mount file.vhdx on HyperV and start

Forget about the export and feed the raw device directly to qemu-img

qemu-img convert -f raw /dev/zvol/rpool/data/vm-100-disk-1 -O vhdx -o subformat=dynamic /file.vhdx

Thanks, I was looking for that

Note to show progress bar you can use -p for qemu-img convert command like:

qemu-img convert -p -f raw /dev/zvol/rpool/data/vm-100-disk-1 -O vhdx -o subformat=dynamic /file.vhdx

And you can do the same for dd by appending “status=progress” at the end.

dd if=/dev/zvol/rpool/data/vm-100-disk-1 of=/file.raw status=progress
