If anyone have a Gentoo KVM image (preferably 10G or less) to share,
please email the details on how to obtain a copy. I will be using it
for development, so the simpler it is the better, with working networking.

The reason I'm asking here is because I'm lazy and don't want to do
work that somebody else has already done. Hopefully sharing it here
will save someone else time as well, so please reply to the list and
CC me (in case I forget to check the archives, as I don't subscribe to
this list).

I wrote a Gentoo install script last spring that I was beginning to
update for building KVM guests a couple weeks ago (until my VM host
hardware up began spontaneously rebooting on me without leaving a trace
in hardware logs...).

I can have another go at it. Any preference for disk size or layout?
Running the script involves (obviously) a great deal of compiling, but
it results in a fully up-to-date system CFLAGS and USE settings as
specified up front...

I'm looking for a more minimal thing that's 5-10G and comes without X
or any other heavy software. I will be using it for OpenRC testing and
similar things, so a big and complicated image is not desirable. I'd
like networking to work though.

Hm. I've never tried building a Gentoo system that...small. Looks
doable, though.

Uncomplicated USE flags are no sweat; a lot of the machinery of the
script is there to cope with quirks of updates involving large sets of
USE flags.

Minimal networking should be no sweat; I'll just enable everything KVM
supports in the kernel configuration. How *much* networking support do
you want, though? Do you need anything more beyond basic layer 3
(IPv4/IPv6) autoconfiguration (DHCP, RAs and IPv4/IPV6 LL), or do you
want netfilter?

No.

Thanks for looking into this. Much appreciated.

Hi,

I can give you my minimal gentoo vm(s). It's a stable gentoo minimal system 
with following aditional software installed (copied from world file):
app-editors/nano
app-misc/screen
app-portage/gentoolkit
dev-util/lafilefixer
net-fs/nfs-utils
net-misc/dhcpcd
net-misc/ntp
sys-apps/portage
sys-boot/grub-static
sys-devel/libtool
sys-kernel/gentoo-sources
sys-power/acpid

The vm has a 50gb harddisk, but the compressed file (qcow2) has ~3gb 
(/usr/portage/* stuff deletetd)
The system is pretty much up-to-date and i have both 32bit and 64bit versions.

However, you need the virtio drivers on the host, because i'm using those 
drivers for the harddisk and network.

Uploading it somewhere shouldn't be a problem but it will take quite some time 
since my upload speed is really slow ;)

I'm not sure how KVM works with this -- is it a static file at 50G?
I'm looking for an image I can use on my SSD, so it really has to be
quite small (preferably maximum 10G).

Thank you for the offer though, and if I can't get a small image
anywhere I could use yours via an external HDD.

The uncompressed image has ~11gb and it would grow as you use it.

However it should be easy to shrink that.
The image has 3 (boot/swap/root) partitions, where the boot partition has 
32mb. If i'm correct you only have to create a new image, make 2 or 3 (depends 
if you need swap) partitions on it, where the first one (/boot) must have the 
same size like in the original image (means 32mb). 
Than you dd the boot partition and copy the files of the root partiton to your 
new image. The files should fit perfectly on a ~10gb hd too since they just need 
~1,5 gb.

I could try it on my own, but than i would take some time...

That is largely acceptable. I would prefer even smaller, but it's more
than sufficient for now. If you have anywhere I can get hold of this
image that would be great.

Well, i don't have any online storage were i could upload it. Looking at 
google i found this site www.transferbigfiles.com but i never tried it and 
uploads will expire in 5 days. If you don't have anything else i would upload 
it there..
