The following list represents the most recent nightly builds occuring from trunk. While these builds represent an installable XenServer environment, they are not intended to be deployed in production and no commercial support is available for them. Importantly, there is no guarantee that an installation based on one of these builds can be upgraded to a release build.
The contents of each ISO file are:
Base ISO: This bootable ISO represents the main installation CD for XenServer. If you are looking to install XenServer, then this is the only ISO you will need.
Binary packages: This ISO represents the driver development kit for XenServer. If you are looking to perform driver development, then this is the ISO you will need. Note that drivers developed using this kit may only work when installed against the specific version of the base ISO corresponding to a given binary package.
Xen/Dom0 Kernel Sources: This ISO contains the sources for the Xen, XAPI and XenServer binaries.
Dom0 SRPMs: This ISO contains the sources for the RPMs required to build dom0.
