# Load the nbd kernel module.

# mount block device
sudo qemu-nbd -c /dev/nbd0 "$VHDX_IMG"

# reload partition table
sudo partprobe /dev/nbd0

# mount partition
sudo mount -o rw,nouser /dev/nbd0p1 "$MOUNT_POINT"

Thank you. This allowed me to mount WSL2 partitions from native linux after running into errors with libguestfs.

Simmilar to @stewSquared I mounted a WSL2 partion aswell. The only thing I had to change was the last command of the mount script, because in my case there were no partitions just /dev/nbd0 so I my command was:
sudo mount -o rw,nouser /dev/nbd0 "$MOUNT_POINT" (notice the missing p1)

Thank you very much! @allenyllee ! Is it also possible with VHDX configured with Bitlocker encryption?

Anyway to resize the image please @allenyllee

On 64-bit Slackware 15.0 I didn't have to specify max_part=16 (default). Using qemu-nbd -r both *.vhd and *.vhdx works without partprobe and I didn't even need nbd-client from the nbd package and I didn't have to reload the nbd kernel module after each try. BTW, I run modprobe -r nbd instead of rmmod nbd for the final cleanup.

Ty! Awesome script 👌
