I have made a Special DSL/Qemu where the DSL playing within Qemu can actually save MyDSL extensions/apps/wallpapers/etc-just like the real thing!
The VHD is approx. 256MB-plenty of room for MyDSL/backups.
The zipped download is only 55MB as the VHD compresses nicely!
Additionally-with the enclosed .sh/.bat files you can play Qemu from your Desktop/USB or while playing DSL via liveUSB!
So, you get both-the real DSL which resides on your USB and saves, and the Qemu DSL on your USB which also saves!
Note-you can run Qemu just by inserting the USB into your PC, no need to restart. Just double-click the .bat/.sh files and choose run.
From within the DSL running live off your USB-open a root terminal and "cd /cdrom" or "cd /mnt/sda1" and then "./mydsl.sh" or "./hydra.sh" Bang!
Additionally-you'll love the Bathory wallpaper!
No need to have Qemu installed-it already is!
Use the Qemu Virtual DSL to setup a DSL server without restarting the PC.
Practice DSL app installs/remasters etc on the Virtual DSL, saving
your real DSL.
Note-don't try to install/partition the vhd's-it will destroy them...
MAKE SURE TO READ THE "README.txt"!!
Note-Apt and GNU-Utils not enabled-this is a "base" DSL with only the Qemu DSL having been setup with minimal apps/themes-but also no apt/gnu-utils enabled.
