You can get the reference platform here: ftp://ftp.mozilla.org/pub/mozilla/VMs. If you are working on one of the community machines, we can also clone these scrubbed VMs onto community machines for you. | |||

By default, the reference platform only runs a console and a VNC server. If you want to use it for actual development you'll probably want to run X.

Reboot, and you should be graphical! CentOS uses 'yum' as it's RPM front-end. You should be able to install most applications/tools you need through it. If you'd like a graphical front-end you can run 'pirut'. | Reboot, and you should be graphical! CentOS uses 'yum' as it's RPM front-end.

= Installing BuildBot = | |||
Because our Buildbot code changes fairly regularly we don't keep a copy of it on the VM. | |||

= Running under VirtualBox = | |||
* Download the machine image as usual, and decompress it to $img | |||
* Import the $img/CentOS-5.0-ref-tools-vm.vmdk (hereafter "hda") and $img/CentOS-5.0-ref-tools-vm_1.vmdk (hereafter "hdb") disk images into your VirtualBox media manager | |||
* Create a new VirtualBox machine that has the disks "hda" and "hdb", in that order (IDE0 master and slave, respectively) | |||
* Edit the VirtualBox machine config to taste: recommendations include adding more RAM and VRAM. Be sure to restart the VirtualBox master process if you edit a machine config. | |||
* Here we de-VMWare the image. The "big difference" is that VMWare uses virtual SCSI devices while VirtualBox uses virtual IDE devices. | |||
*# su root [ see password below ] | |||
*# cd /etc | |||
*# mv vmware-tools bak.vmware-tools | |||
*# mv fstab bak.fstab | |||
*# cp fstab.BeforeVMWareToolsInstall fstab | |||
*# Append the line | |||
/dev/hdb1 /builds/ ext3 defaults 1 2 | |||
to /etc/fstab, using your favorite text editor. Format to taste. | |||
*# Reboot (it's normal to see errors from VMWare during init, since it was mostly disabled) | |||
*# Your image works ...? | |||
These steps can trigger an fsck of /dev/hdb1. This is useful and fast, let it happen. | |||
If you want a graphical environment, be sure to change your runlevel as described above. When you first reboot into a graphical environment, X will fail to start because the xorg.conf is VMWare-specific. In the error dialogs that appear, choosing the option to let X "repair itself" will result in a usable 800x600 display. | |||
= Troubleshooting = | |||
* Make sure you login as cltbld. root will not have the correct PATH and environment variables set. | |||
* You may get an error about "Stale Data" when running this VM in VMware Workstation for the first time. It can be safely ignored. | |||
* If vmware tools doesn't install/upgrade correctly, try running vmware-config-tools.pl as root. | |||
* Bridged Network does not seem to work when using that image in VMWare Server (1.0x), NAT seems to work fine | |||
* The /builds partition might not get added properly add this to /etc/fstab: | |||
/dev/sdb1 /builds ext3 defaults 0 0 | |||
