This guide is to show you how to deploy a MeeGo-enabled OBS appliance with two built-in workers in a virtualized environment for developing for and with MeeGo. The tips is based on http://en.opensuse.org/openSUSE:Build_Service_Appliance and I've tested this within VirtualBox.

You'll need a Virtual Machine like this:

  • At least 1 GB of ram
  • Host must support SSSE3 instructions
  • As IDE primary master ('sda' in machine), latest obs-server.i686-XXXXXX-vmx.tar.bz2 from http://download.opensuse.org/repositories/openSUSE:/Tools:/Unstable/images/ . Unpacking it will give you a vmdk to use or convert with qemu-img to fit with your virtualization software.
  • At least 70 gb virtual harddisk, mounted as IDE secondary master (appearing as 'sdb' in machine')
  • And it must be linked to an actual local network with proper DNS and gateway (no VM NAT) - don't have it on a public network as it opens ports to everyone.

This can also be a physical machine with a physical disk where obs-server.i686-2.0.105-Build1.1.raw.bz2 (bunzipped and dd'ed to a USB stick) can be used as boot device.

Step 1: Boot the VM and set up the virtual harddisk with LVM. =

Power on the machine. At the first setup the image will set itself up to fit with the machine. You'll arrive at a login: prompt where you can log in as 'root'

We need to set up LVM on the virtual disk, sdb. Log in as root and run: (WARNING: this will erase your 'sdb' disk)

  1. This will partition your disk

sfdisk /dev/sdb << EOF ,,8e EOF

  1. This will set up LVM with various file systems. You can adjust sizes as wished.

pvcreate /dev/sdb1 vgcreate "OBS" /dev/sdb1 lvcreate -L 50G -n "server" /dev/OBS vgscan mkfs /dev/OBS/server lvcreate -L 20G -n "cache" OBS vgscan mkfs /dev/OBS/cache lvcreate -L 4G -n "worker_root_1" /dev/OBS lvcreate -L 4G -n "worker_root_2" /dev/OBS lvcreate -L 512M -n "worker_swap_1" /dev/OBS lvcreate -L 512M -n "worker_swap_2" /dev/OBS vgscan mkfs /dev/OBS/worker_root_1 mkfs /dev/OBS/worker_root_2

Step 2: Set up MeeGo supported architectures =

Run the following commands:

  1. Install QEMU for ARM support. This will ask you a couple of times to accept a repository key

zypper install qemu-svn

  1. This will indicate to the OBS which architectures to work with (ARMv7 and i586)

sed s/OBS_SCHEDULER_ARCHITECTURES=\"i586 x86_64\"/OBS_SCHEDULER_ARCHITECTURES=\"i586 armv7el\"/g /etc/sysconfig/obs-server
