Slashdot Mirror

josh asks: "For my next project, I've decided I want to do something related to x86 virtualization (the way VMware does it or Plex86 not Xen/Bochs/etc.) but I really don't know where to start. Googling hasn't been helpful (just look at the results if you don't believe me). Are there any resources for learning about this kind of x86 virtualization? I know virtual 8086 mode wouldn't work, but without that what advantage does something like VMware have over something like Bochs? Are there any F/OSS projects aimed at something along the lines of my thinking? Please enlighten me with any references and resources you might have. Thanks!"

hubertf writes "plex86 is now works on a second Open Source operating system. So far plex86 only supported Linux as host platform, and thanks to Frank van der Linden of Wasabi Systems, it now also works on the i386 port of the NetBSD multi-platform operating system. Tested operating systems include FreeDOS beta 4, MS-DOS 6.22, Red Hat 6 Linux and NetBSD 1.5. See the NetBSD site for more information.

Kevin Lawton, currently employed by MandrakeSoft, is the creator and driving force behind Plex86, the Open Source X86 virtualization software which runs under Linux and now boots several operating systems, including QNX and Windows 98. This is a tricky endeavor, because (among other things), as the plex86 site states: "The x86 processor is not 'naturally' virtualizable. That is to say, it was not designed to run multiple operating systems concurrently." But with enough feints and jabs, Kevin and company have cajoled it into doing so anyhow. He's agreed to answer your questions about virtualization (and / or emulation -- he is the guy behind the also-Open Source bochs project to emulate X86 processors), so please post your stumpers below. Make sure to check out the Plex86 website first, and perhaps read other things about Plex86 on Slashdot. (And "What's the point?" is not a stumper.)We'll forward the top questions on to Kevin, and hear back from him soon.

The list grows of how many OSes Plex86 can boot. Soon you may have an easier time of installing a new kernel (besides turning to page 207 of Running Linux). SAGE wants to know the intimate, personal, steamy details of how much you earn as a SysAdmin. Also, not everyone trusts the proposed data-escrow deal involving Celera and Science. All below, in this episode of Slashback.

Plex those muscles, yeah, and one and two and three ... dhunley expressed himself thusly: "A handful of days after getting Dos, Win95, and Linux to boot, Plex86 does it again! Initial support for booting QNX now works! Screenshot is here!" And shortly thereafter, the very same dhunley wrote: "Plex86 boots NT 4.0! Well, at least to the login dialog box. This is an old bochs disk image file. The mods will be uploaded to CVS soon."

Thanks, d. Watch out soon for an interview with bochs and plex86 lead Kevin Lawton, who promises to take time out from his busy schedule to tell you what's up in the worlds of emulation and virtualization.

While you're here, why not take a tour of the whinery? Apropros the wacky things that people have decided to put in the kernel lately (like GNOME ORBit), Booker writes: "Every time there's a major new kernel release, there's whining on Slashdot about killing uptime, and how much it sucks to have to reboot to get a new kernel. Well, whine no more.

Erik Hendriks at scyld.com brings us Two Kernel Monte, a 'kernel module which allows Linux to load another kernel image into RAM and restart the machine from that kernel.' The only major limitation appears to be that it will not work with SMP machines. Apparently Erik got the idea from the Linux Bios Project."

Now if some smart distribution maker (anyone, anyone) were to integrate that into their updates system, would that be so wrong?

We join this survey already in progress: Marketing Manager writes: "Anyone who's been in the job market knows how tough it is to find information about salaries and compensation. For system administrators, the search is compounded by the varieties of tasks, talents and responsibilities required to get the job done. Now there's something you can do to fix this.

SAGE invites you to participate in the 2000 System Administrator Salary Survey starting December 1, 2000. This annual survey is part of SAGE's ongoing effort to advance Systems Administration as a profession through information and advocacy. By participating in this survey, you join thousands of system administrators in examining the market and defining compensation according to your talents, your location, and your technical prowess."

So now you can find out where you stand in comparison to others with similar positions, perhaps a valuable bargaining chip come contract renewal (or incentive to check out a new city). The results will be available early next year -- automatically sent to SAGE members, available by request to everyone else.

Number One, can't you do anything about that rabble? bluets writes: "Some leading scientists and open-source advocates are attempting to raise awareness that the Celera/Science Magazine deal is a 'Big Mistake.' More details [here]."

And if you didn't know about this, it's only because you're not opening the barrel-of-monkeys Slashdot Science Section often enough. We're considering an experiment where everyone who opens it gets a food pellet, and everyone who doesn't ... well, do we have to bring out the Punishment Stick?

John Roberts writes, quoting the Web page of Plex86 wildman Kevin Lawton: " Plex86 now runs Windows95 on my Linux-Mandrake box, in full virtualization mode!!! That adds Windows95 to the plex86 project's previous list of guest operating systems which it can run: MSDOS, FreeDOS, and Linux. This is full virtualization mode. The CVS server already contains my latest source code. Here's a toast to all the people who have supported plex86 development... [klink, klink, sound of champagne cork popping] Check out this screendump." Woo Hoo! The cost of VMWare may have just risen a bit ...

Next on the chopping block are the MS Windows OSen! "

Adam Bertil was one of a number of people who've written about the recent announcement from www.plex86.org that Plex86 will now run DOS applications. Kevin Lawton apparently did the work and a screenshot is on Plex86 ^[?] .org.

Direct from the mouth of Gael Duval, we've gotten word that MandrakeSoft (Yes, the folks who make Mandrake-Linux. No, it has nothing to do with Mandrake of Enlightenment fame. ) have purchased Bochs and hired Kevin Lawton. Now that Bochs is LGPLed, the Plex86 development can be speed up as well.
