The VMWare image has been updated for the 2009-05-24 server release. The previous image was getting old and updating steps have been reported not easy.
The new image has been upgraded to Debian 5.0, includes a more recent Linux kernel and uses PosgreSQL 8.3 (the required version to work on NGS).
To download and play with the new image, read our VirtualMusicBrainzServer wiki page!
