Cndnsd Vrsn: 5:15PM Thursday 4/20 — Xen, Paravirtualization, & Solaris


Xen, Paravirtualization, & Solaris

The next meeting of the Front Range UNIX Users Group (FRUUG) will be a joint meeting with the Front Range Open Solaris User Group (FROSUG). The meeting will be held at 5:15 P.M. on Thursday, April 20 at the CU Engineering Center, room ECCR-150. We're trying out some potential new permanent locations for FRUUG meetings, and this one comes courtesy of Dirk Grunwald of the Computer Science department. Why the new time? Metered parking on the north and south sides of the Engineering Center becomes available to the public at 5:00. With the late starting time, we'll begin the meeting promptly. More details are in Meeting Location (below).

Xen is a hypervisor that supports an idealized hardware platform onto which you can run your favorite operating systems, each secure in their own virtual machine environment. With Xen, you can run multiple operating systems on the same server, and you can easily support each of your services in a different virtual machine-- allowing for greater security and offering the ability to move operating system instances from server to server as workload demands change. (For a quick background article on Xen, see Nathan Torkington's O'Reilly Network article at: (

At our April FRUUG meeting, Stu Maybee will talk talk about what is involved in preparing an operating system for execution in a paravirtualized hypervisor environment such as that provided by Xen. Given that Stu works at Sun Microsystems, and his favorite operating system is the Solaris OS, he'll talk about supporting it on Xen on x86-architecture platforms.

About The Speaker

Stuart Maybee has been working on operating system internals for more than 25 years. The last decade has been as a member of various Solaris kernel teams at Sun Microsystems. Stu holds a degree in Computer Science from the University of Colorado.

Meeting Location

As you probably know by now, the CU Academic Computing center seminar room that we used for more than a decade is no longer available to us, so we've been checking out some potential new meeting places, the CU Engineering Center being one of them. We've changed the meeting time to accommodate traffic and parking on campus, and hopefully it will allow more people to attend. We'll also be announcing these meetings through the CU Computer Science department, and we'll hopefully gain some synergy with the university as a result. Let us know what you think via the alias "exec" at the domain

This meeting will be held the Engineering Center Class Room wing, room 150, or ECCR-150. This wing is on the southwest corner of the CU Engineering Center, located at the corner of Colorado Boulevard and Regent Drive (see map below). There is parking available on the north and the south sides of the building. Last we checked it becomes free at 5:00, hence the 5:15 meeting start time. (Please double check the meters before you park).

Introducing the Front Range OpenSolaris User Group

FRUUG, originally the Boulder Users Group (BUG), was founded almost 25 years ago because there was no group forum in which local professionals trying to make sense of the then-unsupported UNIX operating system could get help understanding and running the system.

Now that Sun Microsystems has open-sourced substantial portions of its Solaris Operating System, the Front Range OpenSolaris Users Group has formed and has meets to help its members understand the intricacies of compiling, installing, and using OpenSolaris.

Both of our groups are interested in cutting-edge UNIX operating system technologies, so when our interests overlap, we'll be doing joint meetings with FROSUG (you thought FRUUG was hard to pronounce!) You'll find the OpenSolaris User Group on the Web at:

Our Last Meeting

At our last meeting, Sam Falkner gave an overview of DTrace, the dynamic tracing facility provided in the Solaris 10 Operating System.

Announcements, presentation slides, and writeups for past meetings are available in the FRUUG Meeting Archive.
