"This is a formal announcement of Lguest64," Steven Rostedt said in an email posted to the Linux Kernel mailing list. He explained:

"Most are aware of the little puppies (lguest32, or simply lguest, or in some circles "rustyvisor"). But this time the puppies ate a bit too much. No more lean and mean puppies, now we got big fat lazy ones. Running on the hardware that's too lazy to do full virtualization. Yes, lguest now runs on x86_64!"

Steven went on to caution that lguest64 is still a new code base, "lguest64 is still going through a bit of growth pains, but its getting better. It's to a point that we are not that afraid to bring it to the dog show." The list of items left to do include getting SMP working for both the host and the guest, matching Rusty Russel's lguest32 feature set, and greatly optimizing the performance of the code. Steven noted that the goal is to ultimately get the 64-bit version of lguest merged into the mainline kernel.
