Windows without QWT

Yes, it works for me for gnu/linux qubes and Windows qube (with QWT, but it can be irrelevant).

Mostly the same way as you said:

in linuxqube:

  • create file of some size, e.g. file /home/user/mydisk with size 10GiB
  • sudo losetup --show /dev/loop5 /home/user/mydisk

After that you should see a new block device in Qubes Device tray widget.

in dom0:

  • qvm-block attach windowsqube linuxqube:loop5
    Alternative - attach with GUI widget, but I use script.

Now I have a new disk in Windows that I can format. Maybe I formated it in linuxqube, I do not remember that detail.

Note: do not try adding any read-only flags at all steps, because Qubes OS has bug with it in case of Windows target qubes.
