While waiting for the official launch of the newest Sun hypervisor based on Xen, early adopters have the very first chance to see it in action.
The new hypervisor in fact appears in the first 2008 build of Solaris Express Developer Edition (SXDE), labeled 1/08, (which correspond to the Solaris Express Community Edition Build 79b).
Note that while xVM Server is present since a while inside the Solaris Express Community Edition, the SXDE is tested more scrupulously and comes with official support.
Sun also exposed some initial documentation for xVM Server, including details on how to boot the SXDE build to run in xVM mode, how to configure ZFS to expose storage for the virtual machines, how to remotely control guest OSes through the embedded VNC server (Xvnc).
The SXDE 1/08 build is available here free of charge.
The ones which prefer to wait for the official release may want to read the virtualization.info Q&A with Steve Wilson, Vice President of xVM, about the Sun virtualization strategy and roadmap for 2008.
Thanks to Phoronix for the news.
