Apparently there is a problem in the kernel used in Red Hat RHEL 4&5, CentOS 4&5, OEL 4&5, SUSE, Ubuntu 7 and other GNU/Linux distributions that causes EXT2 EXT3 filesystems that are residing on SANs to randomly go read-only !

However if you are using kernel 2.6.18-53.1.21+ or  2.6.22+ you should be ok !

VirtualAppliances.net appliances feature an upgrade to their base distribution, using Ubuntu 8.04 LTS Server Edition, which will be supported by Canonical until 2013.

All of the 32 bit Appliances are using Ubuntu JeOS (Just enough Operating System) which provides a kernel optimized for virtual appliance use.

VMware OVF (Open Virtual appliance Format) images are now available for VMware ESX and ESXi in both 32 bit and 64 bit versions.

Billy Marshall (CEO rPath) thinks that walled gardens will ultimately be overshadowed by clouds because you cannot achieve webscale computing if every application has to run on a server owned by Google … The faster we take the market to cloud computing, the sooner we can kill off the walled gardens through webscale shadows that deprive them of economic sunlight.

The updated version of rBuilder, rPath’s flagship product, provides a new Appliance Model which allows software companies to centrally define configurations for the development, testing and release stages of their appliance.  This makes it easier for multiple groups to coordinate on the development and launch of a new appliance.  It also ensures that consistent processes are used across multiple appliance releases.
