Launching QEMU
Important note: When using purely software rendering in QEMU the GDP HMI will run with a very low frame rate.
It is recommended that you have KVM installed (for example package qemu-kvm) to take advantage of efficient virtualization and graphics acceleration.
To download
- Download or build the gdp-<version> .ext4 (or ext4.gz) and corresponding bzImage files
- If the rootfs image is compressed, uncompress it. E.g.:
gunzip <file>.ext4.gz - Start the VM using the command-line (you may need to replace the name of the bzImage and ext4 files)
NOTE: The qemu command might be "qemu-kvm" or simply "kvm", or "qemu" with a -kvm parameter instead. Try what works on your distribution.
Example:
sudo kvm -kernel bzImage \
-net nic \
-net user,hostfwd=tcp::5555-:22 \
-cpu core2duo \
-hda genivi-dev-platform-qemux86-64.ext4 \
-vga vmware \
-no-reboot \
-soundhw ac97 \
-m 512 \
--append "vga=0 uvesafb.mode_option=640x480-32 root=/dev/hda rw mem=512M oprofile.timer=1"
This command enables the user to ssh into the running image using the command:
ssh root@127.0.0.1 -p 5555 (the password is root)
If you are running an image you have bitbaked you should (from the gdp-src-build directory)
cd tmp/deploy/images/qemux86-64
and then use the above kvm command replacing gdp-<version>.bzImage with bzimage and gdp-<version>.ext4 with genivi-dev-platform-qemux86-64.ext4.
You can configure the root password to change it from the default ('root') by setting the following in local.conf
EXTRA_USERS_PARAMS = "newPassword"
or indeed an empty string.

Introduction
The purpose of this document is to explain how to quickly setup the hardware and install the GENIVI Dev Platform (GDP) on QEMU (qemux86-64).
Important note: When using purely software rendering in QEMU the GDP HMI will run with a very low frame rate. It is recommended that a KVM is used on the linux host to take advantage of the host hardware graphics acceleration.
- Details about this can be found in GENIVI projects mailing list.
Software setup
If you are building from source, ~100GB of storage needs to be available on the host machine
The following is known to work on Ubuntu Linux 14.04 LTS (x86_64)
Quick Start
The Genivi Dev Platform repo utilises git-submodules and source scripts to automate the configuration of the required repository build layers. Allthough this does not fully automate the process, the use of it is advised especially for those wanting to get up and running quickly.
- Install the required development tools on the host by executing the following command.
$ sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat libsdl1.2-dev xterm
- Create a directory for the GDP sources
$ mkdir GDP $ cd GDP
- Clone Genivi Dev Platform, specifying 'gdp-ivi9' branch
$ git clone https://github.com/GENIVI/genivi-dev-platform.git -b gdp-ivi9
- Initialize build environment
$ cd $HOME/GDP/genivi-dev-platform $ source init.sh qemux86-64
- Bitbake the image
$ bitbake genivi-dev-platform
Launch QEMU
- When built from source:
$ cd $BUILDDIR/tmp/deploy/images/qemux86-64/
Install kvm & dependencies
$ sudo apt-get install qemu-kvm libvirt-bin bridge-utils
Execute on the host shell(note '-serial stdio' can be added for serial console access):
To get networking running use -net nic -net user,hostfwd=tcp::5555-:22 instead of -net nic, vlan=0
