It's the "raw" image format. Using the KVM tools, you can create one with "qemu-img create -f raw". Otherwise just use "dd" as in: # create a 2GB raw disk image dd if=/dev/zero of=my_uml_disk.img bs=1m count=2048 > My intent is to have one single image and use it across all different > virtualizations, i.e. use the same image with UML, VirtualBox, KVM etc. > Probably the simplest approach is to use KVM or VirtualBox to install to partition the disk and install the OS on it. Then you just pick a UML kernel compatible with the OS on the disk image and start it. (I'm not sure VirtualBox can handle "raw" images, though.) Use LABEL= or UUID= lines in /etc/fstab, or you'll run into troubles as different virtualization systems use different device names for the emulated disk (e.g., "/dev/ubda" vs. "/dev/xvda" vs. "/dev/sda" etc.) Best regards, Riccardo ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
