-Poky images with QEMU
-=====================
-
-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.
-There are two scripts, runqemu and poky-qemu, one for use within poky,
-the other externally.
-
-QEMU outside Poky (poky-qemu)
-=============================
-
-The poky-qemu script is run as:
-
- MACHINE=<machine> poky-qemu <zimage> <filesystem>
-
-where:
-
- <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)
- <machine> is "qemuarm" or "qemux86"
-
-The MACHINE=<machine> prefix is optional and without it 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.
-
-
-QEMU within Poky (runqemu)
-==========================
-
-The runqemu script is run as:
-
- runqemu <target> <type> <zimage> <filesystem>
-
-where:
-
- <target> is "qemuarm","qemux86","nokia800","spitz" or "akita"
- <type> is "ext2", "nfs", "ext3" or "jffs2". (not all machines support all options)
- <zimage> is the path to a kernel (e.g. zimage-qemuarm.bin)
- <filesystem> is the path to the image (e.g. filesystem-qemuarm.ext2)
-
-It will default to the qemuarm, ext2 and the last kernel and poky-image-sdk
-image built by poky.
-
-
-Notes
-=====
-
- - The scripts run qemu using sudo. Change perms on /dev/net/tun to
- run as non root
- - 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 default NFS mount points are /srv/nfs/qemux86 or /srv/nfs/qemuarm
- depending on the target type.
- - Images built for qemux86/qemuarm contain NFS server which export whole
- rootfs (/) in read/write mode.
- - You can set QEMU_MEMORY to control amount of available memory (default 64M).
- - You can set SERIAL_LOGFILE to have the serial output from the image logged
- to a file.
-
-
-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/<built image>.rootfs.tar.bz2 into /srv/nfs/qemuarm
-
-Finally, launch:
-
-% runqemu <target> nfs
-
-(Substitute qemux86 for qemuarm when using qemux86)
