Launching QEMU

Important note: When using purely software rendering in QEMU the GDP HMI will run with a very low frame rate. If you're doing a lot of work with the HMI, you might want to look into using QEMU with hardware graphics acceleration.

It is recommended that you have KVM installed (for example package qemu-kvm) to take advantage of efficient virtualization and graphics acceleration.

To download

1. Download or build the gdp-<version> .ext4 (or ext4.gz) and corresponding bzImage files
2. If the rootfs image is compressed, uncompress it.  E.g.:    gunzip <file>.ext4.gz
3. Start the VM using the command-line (you may need to replace the name of the bzImage and ext4 files)

Example (Ubuntu)

   sudo kvm -kernel bzImage \
      -net nic \
      -net user,hostfwd=tcp::5555-:22 \
      -cpu core2duo \
      -hda genivi-dev-platform-qemux86-64.ext4 \
      -vga std \
      -no-reboot \
      -soundhw ac97 \
      -m 512 \
      --append "vga=0 uvesafb.mode_option=640x480-32 root=/dev/hda rw mem=512M oprofile.timer=1"

On Fedora, the command is named qemu-kvm, and permissions seem to be set up so you don't need sudo/root privileges:

   qemu-kvm -kernel bzImage \
      -net nic \
      -net user,hostfwd=tcp::5555-:22 \
      -cpu core2duo \
      -hda genivi-dev-platform-qemux86-64.ext4 \
      -vga std \
      -no-reboot \
      -soundhw ac97 \
      -m 512 \
      --append "vga=0 uvesafb.mode_option=640x480-32 root=/dev/hda rw mem=512M oprofile.timer=1"

NOTE: On your distro, the command the qemu command might have different names, "qemu-kvm" or simply "kvm", or "qemu" with a -kvm parameter instead.   Try what works on your distribution.

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.
