Linux inside Linux? PPC


[Log in to get rid of this advertisement]
I am currently using a very stable Dapper install that has "Mac on Linux" working great, even with wireless. What I would like to do now is install a different ppc linux distro on an additional internal HD and run that from my primary linux (Dapper) just like I do with Mac OSX via mol.
Is MOL able to do this or is there another application I need to install? Thanks!

You could use something like VMware Player (or the 'big' edition), but generally you'll need to have a lot too much of resources to waste if you want to run operating systems inside an operating system. It just consumes memory, cpu, ...and what do you get? Probably not much except the joy; if you really need those things, then it's important and for important things you should be ready to pay some money to get things going as smoothly as possible.

I suggest VMWare, if you really want to do that. Even if it sounds nonsense.

thanks for your comments. It's not just the "Joy or discovery" it's about:
"Two words: Workload consolidation.

This is incredibly useful, and is what IBM does with LOTS of their servers.

If the performance is good, you can run two linux installations on the same machine, (say, your database and your web server), and they get the advantages of VERY high speed networking, workload balancing, etc.,
while keeping many of the advantages of running them on different servers."
---------------------------------------
It does seem possible with mol which has the GREAT advantage of not doing hardware emulation which is slow and drains resources. My mac osx runs at nearly native speed and on some apps at native speed, network is the same in linux and mac...
---------------------------------------

shell prompt if one does something like

startmol --linux=/tmp/vmlinuz

with the following lines in /etc/molrc:

linux_initrd: /tmp/ramdisk.image.gz
linux_cmdline: 'ramdisk_size=10000 boot=/dev/ram0 init=/bin/sh'

It should work with any 2.2 or 2.4 kernel. The video mode must be set to depth 32 though.
-------------------------------------
My new project!
thanks--

Keywords are (indeed) VMWare (several editions), Xen, Qemu, VirtualBox (new) and OpenVZ (this one should produce the lowest overhead), virtualization, and paravirtualization. (On Windows, there's Virtual PC and Server, too.)
