Using qemu with poky notes ========================== Poky can generate qemu bootable kernels and images with can be used on a desktop system. Both arm and x86 images can currently be booted. The runqemu script is run as: runqemu where: is "qemuarm" or "qemux86" is "ext2" or "nfs" is the path to a kernel (zimage-qemuarm.bin) is the path to an ext2 image (filesystem-qemuarm.ext2) It will default to the qemuarm, ext2 and the last kernel and oh-image-pda image built by poky. NFS Image Notes =============== As root; % apt-get install nfs-kernel-server % mkdir /srv/nfs/qemuarm Edit via /etc/exports : # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). /srv/nfs/qemuarm 192.168.7.2(rw,no_root_squash) % /etc/init.d/nfs-kernel-server restart % modprobe tun untar build/tmp/deploy/images/.rootfs.tar.bz2 into /srv/nfs/qemuarm Finally, launch: % runqemu nfs (Substitute qemux86 for qemuarm when using qemux86) Notes ===== - The runqemu script runs qemu with sudo. Change perms on /dev/net/tun to run as non root - You can set QEMU_MEMORY env var to control amount of available memory ( defaults to 64M ) - There is a bug in qemu in that means occasionally it will use 100% cpu. You will need to restart it in this situation. More Info ========= - See http://o-hand.com/~richard/qemu.html
