In SDK 1.1 update release, the launching scripts has been updated to check whether the KVM module is loaded. If not, QEMU will be started without "-enable-kvm" option. So with 1.1 update release, user should be able to launch QEMU always, although slow if KVM is not enabled. We did not start KVM automatically because of the [http://bugs.meego.com/show_bug.cgi?id=10075 KVM] bug.

This error is due to SELinux security policy settings. There are two possible solutions:

<li>Temporary (needs to be repeated on each reboot)

<li>Permanent 
In the <code>/etc/selinux/config</code> file, set the value of the <code>enforcing</code> variable to <code>disabled</code>. 
You will also need to do <code>sudo /usr/sbin/setenforce 0</code> to make this change immediately. SELinux should be disabled on the next boot.

After disabling the selinux enforcement policy the QEMU version from 1.1 SDK can then be launched via mad tools:

<td>Launching QEMU just shows a decorator bar. X seems to start and ssh could work, but no UI was shown </td><td>Usually that is because the UI program "duihome" crashed for some reason. One possible reason is that there is no sound card available in host system, which crashed "sysuid" in QEMU client OS, and as a result, duihome crashed. There was a [http://bugs.meego.com/show_bug.cgi?id=11367 bug 11367] reported against "sysuid" in MeeGo UX. [http://bugs.meego.com/show_bug.cgi?id=9351 Another bug 9351] could be a reference of this issue. If the sound card works in you host system, and sometimes UI shows and sometimes not, one thing you could try is to ssh into the MeeGo, delete the file "/tmp/mstatusbar_pixmap_handle", or simply delete everything in "/tmp/", and then try again. The file contains a handler shared between processes, which seems to be the direct reason causing "duihome" to crash.</td>

<td>Performance of MeeGo OS in QEMU is slow. Animations and screen changes is slow (3-5 seconds for each action)</td>

Right now the bug has been fixed and GL acceleration will be enabled soon. With GL acceleration, performance could be much better. Meanwhile, the netbook target in SDK 1.1 release does have GL acceleration, which is the same as the July release. If you are running netbook and it is still quite slow, please check that the host machine has enabled hardware graphic acceleration.

<td>Launching QEMU works, but ssh does not work</td><td>The most possible reason is that sshd daemon was not started successfully. This was seen by some people and the root cause is that key files for ssh in MeeGo image was destroyed, possibly because of abnormal exit of running image. It could be fixed deleting key files in /etc/ssh in the MeeGo image. If you are able to boot into the image, then open an terminal, and
sudo rm -rf /etc/ssh/*key*
sudo /etc/init.d/sshd start
On Linux host system, you could mount into the image and do the change directly as well:

== Build environment ==
mingw is used to build QEMU from source on Windows. 
Go to [http://sourceforge.net/projects/mingw/files/ MinGW download page], download mingw-get-inst-20101030.exe, and run the installer. 
Use pre-packaged repository cataloguse 20101030 
select "C Compiler", "MSYS Basic System" and "MinGW Developer ToolKit" 

After installing minGW successfully, open an msys terminal by clicking c:/mingw/msys/1.0/msys.bat (suppose minGW is installed in c:/mingw. The same to below when "c:/mingw" is used) 
run below commands to install more packages needed:
mingw-get.exe install libpthread
mingw-get.exe install libexpat

create link for libpthread.a
cd /mingw/lib
ln -s libpthread.dll.a libpthread.a (windows may create hard file instead of symbolic link. It is fine as well)

Download source package of libSDL-1.2 from [http://www.libsdl.org/download-1.2.php here]. Copy SDL-1.2.14.tar.gz into c:/mingw/msys/1.0/home/xxx/. Then in msys terminal:

Zhiyuan: /* Run meego image */

This page describes how to run MeeGo image.

== Prepare environment ==
(Suppose there is shell window available in you system, although it not really necessary)

Download QEMU binary from http://osve-files.sh.intel.com/pub/misc/sdk/windows/qemu.tgz and get binary with
tar xzvf qemu.tgz

Download image file from http://osve-files.sh.intel.com/pub/misc/sdk/windows/meego-handset-ia32-pinetrail-mtf-1.0.90.2.20100914.1-sdk-1.1.80.20101023.1936-sda.raw.bz2, and get the image with:
bunzip2 meego-handset-ia32-pinetrail-mtf-1.0.90.2.20100914.1-sdk-1.1.80.20101023.1936-sda.raw.bz2

Download the command line option from http://osve-files.sh.intel.com/pub/misc/sdk/windows/command.sh

===(optional) install kqemu accelerator for QEMU on Windows ===
Download package from http://wiki.qemu.org/download/kqemu-1.4.0pre1.tar.gz

Get the kqemu.inf and kqemu.sys files from above package

For WindowsXP system, right click the kqemu.inf file and select "install".

For WindowsVista system, edit the kqemu.inf file to do below changes, and then right click the kqemu.inf, select "install".

[DefaultInstall.NT] --> [DefaultInstall]
[DefaultInstall.NT.Services] --> [DefaultInstall.Services]
[Uninstall.NT] --> [Uninstall]
[Uninstall.NT.Services] --> [Uninstall.Services]

Start the kqemu manually:
net start kqemu

Notice: The kqemu could only be used on 32-bit windows system. 64-bit Win7 or WinXP could not work with kqemu

== Run meego image ==
edit the command.sh to set the correct path for qemu.exe and pc-bios. Then run the command:

./command.sh

This command will boot into command line window. Log in with "meego" account and password "meego", then start the UI by running:

uxlaunch

UI will show up.

This is verified on WindowsXP 32-bit with kqemu enabled on Dell OPTIPLEX 760.

Notice:

Screen output will be in the same directory as qemu.exe, in the two files of stderr.txt and stdout.ext

GL acceleration is *not* enabled
