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 <target> <type> <zimage> <filesystem>
|
|
|
|
where:
|
|
|
|
<target> is "qemuarm" or "qemux86"
|
|
<type> is "ext2" or "nfs"
|
|
<zimage> is the path to a kernel (zimage-qemuarm.bin)
|
|
<filesystem> 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/qemuarm
|
|
|
|
Edit via /etc/exports :
|
|
|
|
# /etc/exports: the access control list for filesystems which may be exported
|
|
# to NFS clients. See exports(5).
|
|
/srv/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/qemuarm
|
|
|
|
Finally, launch:
|
|
|
|
% runqemu <target> nfs
|
|
|
|
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.
