• Running linux in vm on li

    From Dumas Walker@VERT/CAPCITY2 to JAZZY_J on Sun Jul 15 19:33:00 2018
    It depends on the purpose of the VM. For example: I have a VM that
    handles just mail. I have no XServer on it because I only access it
    through shell or with the email client.

    It is actually to run a BBS on. Specifically, I have a new 64-bit UP Board that currently hosts my 64-bit synchronet bbs (compiles and works great on there, btw, I prolly need to tell DM), and I still have a 32-bit debian box that is hosting my older DOS bbs. I tried running in under dosemu on the 64-bit os and it does not like some of the dos stuff, so I am trying the
    32-bit debian in a vm with dosemu installed. We will see how that goes.

    So far, the vm works, and dosemu works (real slow!), but I am not so sure
    that binkley will load. FYI, I am using ubilinux which is the recommended 64-bit debian variant for the up board... it has drivers for it.

    If you are using QEMU/KVM or LXD you can.

    Someone told me to use ip instead of brctl. I could only get ip working
    once. Brctl seems to set the bridge up perfectly, and the vm gets a IP
    address assigned from the router!

    (3) Will I be able to access other hardware while in the vm, like a usb port and whatever might be connected to it?

    Yes. It must be in the config file of the guest OS. If you are using QEMU/KVM I suggest virt-manager to help you visualize the management of
    the config files. It makes it a lot easier and faster than writing
    your own config files.

    I am using QEMU without KVM right now. I was able to get pretty easily get
    the vm to recognize the connected serial port and modem... at least well
    enough to echo at commands to the modem and make the lights blink. :)

    Happy computing. I have a few servers. Most have both KVM/QEMU and
    LXD virtuals/containers on them. I've found that VirtualBox does a
    wonderful job. It's just that it is very similar to KVM/QEMU and I
    don't see a purpose for it on a Linux Machine. However, I do have
    VirtualBox running on my Microsoft Hosts.

    Thanks!

    It sounds like he's trying to run a Linux VM on top of an already working linux system. why would you suggest he wipe his system and install a specialized hypervisor like Promoxox?

    Exactly. Trying to emulate a 32-bit install on a working 64-bit machine. Proxmox looks pretty neat but I like the linux distro I currently have. :)

    once you virtualize you can mix and match your vms, my bbs is a 32bit ubuntu vm, and i have a lamp server (ubuntu 64bit) concurently and a windows box a lubuntu and another vm debian 64.

    You could even virtualize a win95 if you felt like it.

    This is pretty much what I do with my other BBS. I am running MajorBBS on Windows XP in a Virtual Machine on MacOS. I have an old 2006 Black Macbook that was collecting dust. I was going to sell it when I decided to turn it into a MajorBBS server and it actually runs surprisingly well.

    If you would have told me in the early 1990's that I'd be running MajorBBS on a Apple computer in 2018, I wouldn't have believed you, lol.

    In 2010, I had a Mac Mini and ran my BBS in a Windows 2000 VM on it for a while. It ran okay, although not as speedy as in other configurations I've run it in. Currently I'm running my BBS in a Windows 7 (32-bit) VM in VirtualBox running on a Linux Mint host (I run other stuff on that machine), with an Intel i5-9XX something, and it runs very well on it.

    If you would have told me in the early 1990's that I'd be running MajorBBS on a Apple computer in 2018, I wouldn't have believed you, lol.

    Yeah, things can change a lot. I'm not sure there was much virtualization software for the Mac before they started using Intel processors. I've heard rumors that Apple is planning to switch to ARM processors for their Mac starting in 2020 though.

    Well ARM actually doesn't make processors, ARM makes processor designs and licenses the designs to other companies to make their own processors with ARM designs. So Apple would be making their own ARM-based processor.

    Well ARM actually doesn't make processors, ARM makes processor designs and licenses the designs to other companies to make their own processors with AR designs. So Apple would be making their own ARM-based processor.

    Kind of like RISC? Although, I have heard that RISC is more open than ARM.

    With ARM licensing their designs, that would make sense for Apple ro make their own ARM chips. I would beinterested how that will work out for them both sales wise and software wise.

    My understanding is that RISC is an architecture (Reduced Instruction Set Computing). Any CPU maker can make a processor with a RISC design. RISC isn't a specific company that is more open than another.

    With ARM licensing their designs, that would make sense for Apple ro make their own ARM chips. I would beinterested how that will work out for them both sales wise and software wise.

    Apple has switched CPUs in their Macs a couple times before (once from Motorola 68k to PowerPC, and then from PowerPC to Intel). I'm sure they will probably be okay. I think it's a little disappointing though, because Macs with Intel means they can run both OS X and Windows easily. Compatibility will suffer a bit, but that will be temporary. But there will probably be a point where Intel-based Mac apps won't be updated to run on ARM-based Macs, so Mac users won't be able to use them anymore.

    I imagine Apple is frustrated with Intel right now, but companies sometimes go into a bit of a slump, but I don't think it should mean Apple should drop Intel.

    Could be some interesting crossovers between desktop and iPhone/iPad apps in this.

    only difference between a 68k and PowerPC was 16-bti vs. 32-bit, the changet o Intel was significated because the Intel CPU wasn't compabible with 68k/PPC code which is why for a while OSx could run on both CPUs until they had enough of an Intel base that they phased out support for Motorola CPUs in 10.5.x (Leopard I think).

    Apple has never been one for Windows, and at this point I don't think it matters what CPU the platform runs on. Also, doesn't Win10 run on ARM CPUs? I used to love Apple systems, now they are just sealed bloatware.

    I'm responding to an old message, sorry if you guys have moved on a long time ago. ;)

    hmm, I always thought the transition from 68k to PowerPC was also significant because the PowerPC used a different instruction set. I've always heard Apple had to use emulation to be backwards-compatible with 68k. http://lowendmac.com/roundtable/12rt/026-powerpc-transition.html
    "Perhaps the most important feature of the new Power Macs was Apple's inclusion of a 680x0 emulator as part of Mac OS, which allowed PowerPC Macs to run most existing software efficiently on the new processors, much as Rosetta would later allow Intel Macs ro run PowerPC software."

    Apple has never been one for Windows, and at this point I don't think it

    Since they transitioned to Intel, they (or at least, Apple users) have always advertised the ability to run Windows as an advantage though.

    matters what CPU the platform runs on. Also, doesn't Win10 run on ARM CPUs? I used to love Apple systems, now they are just sealed bloatware.

    I've heard Microsoft has been working on a version of Win10 that runs on ARM, but I don't know of any such devices on the market yet. I thought it was still in development, and that PC makers were still working on ARM-based Windows devices.

    Also, I'm not sure what you mean by "sealed bloatware"? People often say Apple Macs don't include all the bloatware that is usually installed on Windows systems from major PC makers.

    I think the CPU does matter, at least to some extent, because changing the CPU that the system runs on would require an emulator for a period of time until their software is updated to run natively on the new CPU. And some applications might never get updated.

    It's actually more significant than that, even. The PowerPC's emulation of the 68k is actually at the hardware level, rather than in software. Since the PowerPC was developed by Apple, IBM, and Motorola, one of it's main functions was specifically to replace the 68k, and software-level emulation at that point wasn't anywhere near efficient enough to do so effectively. So the emulation is built into the chips themselves.

    Apple stopped supporting PowerPC after Leopard... but the Classic MacOS -- OS9, whatever, which still had a lot of native 68k libraries -- would run on any PowerPC Mac, up to the G5 (the G5 had to do it from within OSX because of a firmware change; the G4, though, could boot as OS9).

    Interesting.. I do remember hearing somewhere that Mac software for 68k sometimes ran better on the PowerPC - Probably due to the hardware backwards compatibility.

    Absolutely. The earliest PowerPC chips, while faster overall the the 68040s that came before them, didn't execute code quite as fast. So a 100Mhz PowerPC 601 actually performed 68k stuff slower than a 25Mhz 68040, but that was fixed later on by adding cache and whatnot and, I think, dynamically recompiling some of the code to native PowerPC.
