Running Genntoo inside a QEMU VM

Hi All,

I'm wondering if anyone has tried to run Gentoo on a QEMU virtual machine.

I'm currently testing Qt/Embedded 4.4.0 and it would be really useful to have
several virtual machines to test it on, specifically arm, mips & PPC.

I've looked at the arm handbook and it says there's only stages for the old arm
ABI, it that still the case? I need to test against EABI really.

Cheers,

Tom

Hi Tom,
you can check this link [1]. It worked fine for me.

Re: Running Genntoo inside a QEMU VM

Hi Tom,

I'm running a couple of gentoo servers on top of KVM very successfully. 
KVM basically is QEMU with hardware virtualization support.
You may want to use a 2.6.25 kernel as that has support for the new 
paravirtualized virtio block and net devices which speed things up. Also 
you should build a tickless kernel if possible as that should reduce the 
CPU an idle guest uses.

Performance and stability are top notch in my experience.

I did not set up architectures other than x86 and x64, though.

regards,
Felix

Hi!

Arm eabi works fine
both native and cross compiler if you use at least gcc-4.2
binutils-2.18 and glibc-2.7
i haven't tested eabi with uclibc yet

uclibc stages in 2008_beta1?

Hi,
during mirror synchronization I would swear that I've seen new uclibc stages.

Later and now I cannot find them. Is my new uclibc stage only wishful-thinking 
or it reallly will be available? and if, then when?

ELC/08

Anybody planing to attend the Embedded Linux Conference next week in the
bay Area? I will probably be there next Thursday with Rob Landley.
Towards the end of his 2 hr Lecture/Tutorial it will include the use of
Gentoo as a staging environment for embedded development and cross
compilers. I hope to make it over Wednesday also for the afternoon-BOF.

It's limited to only a few arches right now.

profiles for reduced disk usage

Does anyone know if there is a portage profile for reduced disk writes? 
I just got an EEE pc and I'm experimenting on a USB stick before I write 
to the SDD. I'm sort of guessing that such a profile would basically 
just slightly alter the default configuration files of certain apps to 
either turn off logging or to mount temporary directories as tmpfs.

Does such a profile sound closer to embedded, or would it be a desktop 
profile without the logger, etc, etc.

It seems the line between embedded and default is growing thinner every day!

I guess I'm looking for something that's more or less a Desktop profile, 
but something that would be more suitable for flash-based devices, like 
the OpenMoko/Neo, EEE Pc, or a Maemo.

Nedd, I've been using qmerge with my arm packages by the way, and it's 
fantastic. I'm really looking forward to using it more. At some point 
I'm hoping to use, augment or write a graphical app for installing 
packages locally and also remotely via ssh or some web interface.

Cheers,

Chris
