-Poky images with QEMU
|
|
|
-=====================
|
|
|
+Using OE 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 runqemu, one for use within poky,
|
|
|
-the other externally.
|

|
|
-QEMU outside Poky (runqemu)
|
|
|
-=============================
|
|
|
+OE-Core can generate qemu bootable kernels and images with can be used
|
|
|
+on a desktop system. 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:
|
|
|
|
|
|
- MACHINE=<machine> runqemu <zimage> <filesystem>
|
|
|
+ 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)
|
|
|
- <machine> is "qemuarm" or "qemux86"
|
|
|
+ <filesystem> is the path to an ext2 image (e.g. filesystem-qemuarm.ext2) or an nfs directory
|
|
|
|
|
|
-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 <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.
|

|
|
-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 core-image-sdk
|
|
|
-image built by poky.
|
|
|
+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
|
|
|
+ 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 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)
|
|
|
-
|
|
|
+ - 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.
