Hello Jui-hao, Please see my ideas below. As Chris pointed out, I am trying to run the current ARMv6 code based on qemu. Once I finished I will post them on the project wiki. Stay tuned ... (I CCed this to the project mailing list for others who are experiencing the similar problems and also for those who want to add more to the explanation ...) -Yifan On Tue, Oct 26, 2010 at 11:49 PM, Jui-Hao Chiang <juihaochiang at gmail.com>wrote: > Hi, Yifan: > > This is Jui-Hao Chiang, student from Stony Brook University, USA. > As for the kvm-arm installation, I have read your article on the forum > list. > But I still have some problem about booting the emulator. > The following is my installation step, and question is inlined in step 8 > and 10 > > Hope you can share the difference between your steps and mine. > Many Thanks, > Jui-Hao > > > InstallationBased on > https://wiki.ncl.cs.columbia.edu/wiki/AndroidVirt:Guides:Development_Environment#Repositories > > 1.

Maybe the "error" messages you saw do not matter. Anyway, you do not bother to build the whole android system or sdk if you only want to try the androidVirt code. Just use the prebuilt emulator and disk images. Here are the branches I tried: host kernel (directory "linux-android-common") - branch "android-goldfish-2.6.27-kvm-upstream_qemu" qemu on the emulated target (directory "qemu") - branch "armkvm-upstream" guest kernel (directory "linux-guest") - branch "v2.6.17-lpv" You may also need to modify the file "configure-qemu.sh" in android-extra/scripts before compiling the target qemu: 1. add "--disable-werror" to "OPT_FLAGS" 2. add "-I$KERNEL_DIR/include -I$KERNEL_DIR/arch/arm/include" to "CFLAGS" > > - > > > 1. export > PATH=$PATH:~/CodeSourcery/Sourcery_G++_Lite/bin/:~/kvmarm/android-extra/scripts/:~/android-sdk-linux_x86-1.0_r2/tools/ > > 2.
