The scripts currently support booting ARM, MIPS, PowerPC +and x86 (32 and 64 bit) images. The scripts can be used within the OE build +system or externaly. + +The runqemu script is run as: + + runqemu <machine> <zimage> <filesystem> + +where: + + <machine> is the machine/architecture to use (qemuarm/qemumips/qemuppc/qemux86/qemux86-64) + <zimage> is the path to a kernel (e.g. zimage-qemuarm.bin) + <filesystem> is the path to an ext2 image (e.g. filesystem-qemuarm.ext2) or an nfs directory + +If <machine> isn't specified, the script will try to detect the machine name +from the name of the <zimage> file. + +If <filesystem> isn't specified, nfs booting will be assumed. + +When used within the build system, it will default to qemuarm, ext2 and the last kernel and +core-image-sato-sdk image built by the build system. If an sdk image isn't present it will look +for sato and minimal images. + +Full usage instructions can be seen by running the command with no options specified. + + +Notes +===== + + - The scripts run qemu using sudo. Change perms on /dev/net/tun to + run as non root. The runqemu-gen-tapdevs script can also be used by + root to prepopulate the appropriate network devices. + - You can access the host computer at 192.168.7.1 within the image. + - Your qemu system will be accessible as 192.16.7.2. + - The script extracts the root filesystem specified under pseudo and sets up a userspace + NFS server to share the image over by default meaning the filesystem can be accessed by + both the host and guest systems. + |
