Installing GENTOO 2008.0 on a QEMU DISK IMAGE (and KDE4).

Thanks for relinking the page.

Why is this still delinked from the front page?

Do you mean the "Popular in the Forums" section, which I assume is automatically generated based on posting or reading activity ? If the thread is delinked from there it probably just means the thread was not sufficiently popular at that moment. I imagine the "relinking" happened as a result of your own posts to the thread.

Yes, I mean the "Popular in the Forums" section, which is automatically generated after 5 replies are recorded by a thread.

In this thread there were 12 replies (2 were just checks to see if the thread had been relinked and have been deleted) before it appeared on the "Popular in the Forums" section.

For those who just want to see what the script does, here are the commands:

echo -e "n\np\n1\n\n8\nn\np\n2\n\n70\nn\np\n3\n\n\nt\n2\n8 2\na\n1\np\nw"|fdisk /dev/hda
(partitions the virtual harddisk)
mkfs.ext2 /dev/hda1 (formats the boot partition)
mkswap /dev/hda2 (sets up the swap area)
mkfs.ext3 /dev/hda3 (formats the Gentoo 2008 partition)
mkdir /1 (creates a mount point for the 3rd partition)
mount /dev/hda3 /1 (mounts the 3rd partition)
cd /mnt/livecd
tar -cpf - * | tar -C /1 -xpf - (copies the LiveCD)
rm -f /1/usr/portage/{eclass,profiles} (removes some links)
tar -xjpf /b/portage*.tar.* -C /1/usr/ (unpacks the copy of portage in /b)
rm -f /1/etc/gconf /1/var/db (removes more links)
mv /1/usr/livecd/gconf /1/etc (copies configuration files)
mv /1/usr/livecd/db /1/var (copies emerge database)
rm -fr /1/usr/livecd (some house-keeping)
rm -f /1/home/gentoo/Desktop/* (more house-keeping)
rm -f /1/etc/runlevels/default/{autoconfig,local} (important)
awk '{print gensub(/cirrus/,"vesa","g")}' /etc/X11/xorg.conf > /1/etc/X11/xorg.conf
(corrects the graphics configuration)
cp /etc/profile.csh /1/etc/profile.csh (copies eselect configuration)
cp /etc/ld.so.conf /1/etc/ld.so.conf (adds /usr/local/lib to ld.so.conf)

This may be of some interest:

Compiling the Kernel Virtual Machine (version 71).

Oh,... Come on,.. someone must have some comments/improvements to the script.

[Kano]

Pretty bad style, better would be:

sfdisk ...<EOT
...
EOT

instead of echo|fdisk at least. makes it more readable. Next thing is: do not hardcode devices, thats stupid - especially that hda is not used in newer kernels with libata. You can always use the same marker, it is not needed to use differnent ones with every use. Instead of echo "..." > use:

cat > filename <<EOT
...
EOT

In case you do not need vars in it you can use a trick that you do not need to escape chars, when you use:

cat > file <<'EOT'
...
EOT

[Jade]

Thanks for the tips Kano.

Anyone know of a guide for a more recent KVM version?

Yeah,... here is a guide for KVM 86
