Hello!
I need to setup a test-network of at least 3 machines. I searched for emulators on our platform but currently I am stuck:

I am on an ibook g4, 512 mb ram.
I tried to install user-mode-linux but failed on the very first step:
compiling a kernel with
Code:
ARCH=um

The error message was something like: arch/ppc/Makefile-ppc not found or something (although there was a Makefile-powerpc -- renaming it did not work...)
And searching the net it seems there is no ppc port of UML -- or am I wrong?

So i tried qemu -- right now using q (kju-app.org) on MacOSX but the performance is...well...I am installing a minimal debian (x86 -- would ppc perform better? did not manage to boot the iso file) for quite some time now....

Has anyone any idea/alternative? I do need three virtual machines (minimal: only the basic linux tools) to test network/firewalling...

Thank you!

and then:
Code:
emerge qemu

(No xen, no uml, no kvm....) anybody?

Unfortunately, all these tools only work on the x86 system.

Yeah, I know...that is the problem...
Anyway, I think I have found an alternative:
openvz

Looks promising for my needs...if only I could apply those damn patches.... :wink:

By the way, a nice comparison of available virtual machines is on Wikipedia

bye, mesch.t

hi!
It works under ppc - I did not use the ebuild!

I use a 2.6.18 kernel with the patches from openvz and followed their instructions to set up my environment...
The only option in the kernel which has to be 'unset' is: CONFIG_VZ_CHECKPOINT (not supported under ppc)

no problems encountered so far...its really cool...
bye, mescht

also, an other bit of informations
(*) it should work in the future: http://www.nosreme.org/projects/umlppc/
(*) it should work, but not at the present: http://linux-vserver.org
(*) the state of art: "poor performance isolation" http://virt.kernelnewbies.org/TechComparison

:' ( does it mean "if you want to virtualize your HW, you have to stay with x86" ?
