Using OE images with QEMU
|
||
|
|
=========================
|
||
|
|
|
||
|
|
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:
|
||
|
|
|
||
|
|
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.
