dsl embedded usb : daily useForum: DSL Embedded Topic: dsl embedded usb : daily use started by: philemon_siclone Posted by philemon_siclone on Aug. 18 2005,07:50
Hello,From what I understood : 1) The only easy way to save your work using qemu is to save it on the hdb image (the "qemu\harddrive" file). 2) this file is not "mountable" under windows. 3) hence, the only way to access your files with windows is to install a ftp server in windows or to configure shared folders that will be accessed through samba. 4) So being able to use DSL-embedded for real work depends strongly on the host windows configuration. 5) This means it is not a "mobile" solution anymore. 6) So (expressed in rather crude words, due to my poor english), putting it on a usb key seams pretty pointless. Thus my question : Does someone really work with dsl-embedded on usb, or is it just for testing/fun purpose ? Regards, Phil Posted by lra on Aug. 18 2005,08:45
linux can mount raw images or isos that qemu reads/writes to.you can use samba to access windows ntfs drives - see mr helix's solution in this forum or, you could access a physical cd rom in qemu: (http://www.h7.dion.ne.jp/~qemu-win/HowToFloppyCdrom-en.html) -cdrom //./d: in the batch file. though i've never tried it, perhaps you could write to cd and use that as a means of swapping data? download the latest qemu as well. hope this helps Posted by MikeNavy on Aug. 18 2005,11:46
Hello,You are a happy man able to write in "harddisk" mounted as "hdb" in dsl (I can mount this disk but in read only mode, no way to have write permission). Note that "harddisk" can be read from within windows, using "explore2fs", an utility able to read the content of ext2fs image files. It is a freeware, just google it and download it.

Thank you to you two for these accurate answers. I'll try both solution : maybe there is a way to automate them (synchronizing hdb when session begins and synchronize back (hdb->USB) when session ends).
I have no problem if I am root (actually this issue doesn't seem to be "embedded-related", because I've got to be root as well in order to write to my harddisk when I boot from CD or USB). Phil Posted by lra on Aug. 18 2005,19:41
slightly off-topic question here, but can linux mount qcow images?does explore2fs read qcow as well? the thought of having a hdimage that grows as needed would be beneficial. thanks Posted by cbagger01 on Aug. 18 2005,21:29
What an EXCELLENT idea!If the DSL embedded "harddisk" was a qcow image instead of a fixed size 60MB image, you could free up a lot of unused space on your Pendrive. The only downside that I can think of is this: Can you mount a qcow image file from inside Native DSL? I know that it is possible to mount a standard image file from inside native DSL (when not running embedded) because this is how the "5-way" installations work today. If it is possible to mount a qcow loop image from within the DSL kernel, this would be a win-win situation. Otherwise, it would be impossible to use a qcow image with a "5-way" install of DSL-Native/DSL-Embedded Posted by lra on Aug. 19 2005,09:00
i've done some reading up on the subject and no you can't mount qcow images :/

>1) The only easy way to save your work using qemu is to save it >on the hdb image (the "qemu\harddrive" file).WRONG the easy way is to use the qemu savevm ie... save virtual machine state option and then use loadvm to load it.... also you make make a hard disk image of any size and save your backups pkgs whatever to it... just like /hdb... you have to be root to copy files to virtual drives like hdb so maybe you should sudo chown dsl /mnt/hdb.
