I have a working version based on dizzy's method. However, I will not be implementing the persistent home at this time. It uses the standard backup/restore and mydsl system consistent with the way things work now.

cbagger01, I must admit that I'm a complete newby to this project, and more issues escape my comprension, but seems to me that you and Dizzy have a complete and deep undestanding of this issue.

It's realy amazing the roadmap that you have sugested in your last message and I hope that you get the needed help for more able people that myself.

Thank you very much for your detailed response!

Saludos,
Rafa

Ok, after a couple of bad starts, I have a LG XTick 2.0 USB Drive booting with DSL. Y have also copied the embebed distribution so, now I have a "dual boot" system.

Now the last thing... How can I mount the HARDDRIVE virtual drive for the dsl-embebed inside de "native" DSL (the one working when I boot from the USB Drive)? I have read a message from drizzle about this at the begining of the thread, but it seems to me that I shoud replace some files on the startup image... a little advanced for me now

.

Thanks for your help and patience

Saludos,
Rafa

Depending on how your virtual hard drive is formatted, you can mount it by doing the following:

First, make sure that your thumbdrive (usually /dev/sda1) is mounted. There should be a green light for it on the mount.app bottom right corner of your desktop. Then open a xterminal window and type:

sudo su
mkdir /mnt/qemuhd
mount -o loop -t ext2 /mnt/sda1/dsl_embedded_directory_name/harddrive_image_filename /mnt/qemuhd

You may need to replace the "/mnt/sda1" with "/cdrom" or "/cdrom2" or "/mnt/sdb1" depending on the location of your USB drive and whether or not you have booted directly from the USB device.

Now if your hard drive image contains a partition table and multiple partitions (you will see /mnt/hda1 instead of /mnt/hda when running from qemu-embedded) then you will need to mount it differently.

Je, je, je, I'm new to the DSL world, but I can determine if a drive is mounted :;):

I have followed your instrucctions and it works! I can read and write the virtual HD. The only thing that I haven't see before is the -o loop in the mount command (any technical clue, please?). I belived that this need a modified loop.o (from the dizzy message).

Well, now the problem is when I try to restore a system backup from /mnt/qemuhd. I have put qemuhd as the backup/restore unit. When I press the "Restore" button, the window hang.... Perhaps is looking at /dev/qemuhd... Any way to use this virtual HD for the backup/restore?

Buy I can use myDSL with the optional DSL modules stored in /mnt/qemuhd/optional downloaded within a previous qemu session.

I the backup/restore finaly works this is all the "duality" that I need by now.

Thank you very much!!
Rafa
