With this higher-level stuff, you get to share all of the Linux caching, and can do things like sharing libraries pretty naturally. They are also much lighter-weight to create and destroy than full virtual machines. We were planning on doing some performance comparisons versus some hypervisors like Xen and the ppc64 one to show scaling with the number of virtualized instances. Creating 100 of these Linux containers is as easy as a couple of shell scripts, but we still can't find anybody crazy enough to go create 100 Xen VMs. Anyway, those are the things that came to my mind first. I'm sure the others involved have their own motivations. -- Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
