Installing gentoo on VirtualBox

Host preparations:
Open VirtualBox
-Click new and follow the instructions on the screen.After you have finished, go to cdrom and attacht rescuecd.iso on it.
-Done with creating the guest oss, then click start to boot into the rescuecd.iso.

/**********************************************************************/

Instructions (general installation-routine for gentoo)
Please feel free to skip this and use the excellent official handbook.

-Prepare network, net-setup will do.But ping isnt working even though connected to internet.I used to open firefox for the handbook :)
-Click start to Boot rescuecd, after the process type "startx" and then gparted to prepare disks.Skip the "startx" if you feel good.
-If you choose to startx then gparted is excellent, if you stay on the console fdisk is your friend.

Example for VB VM:
-Table:
/dev/hda1 logic partition
/dev/hda5 /boot
/dev/hda6 /
/dev/hda7 /home

Installation of tarbals stage && portage
Mount partions:
Code:
#mount /dev/hda6 /mnt/gentoo
#mkdir /mnt/gentoo/boot
#mount /dev/hda5 /mnt/gentoo/boot


Download the tarbals:
Code:
#cd /mnt/gentoo
#wget "http://ftp.snt.utwente/pup/os/linux/gentoo/releases/x86/current/stages/stage3-i686-2008.0.tar.bz2"
#wget "http://ftp.snt.utwente.nl/pub/os/linux/gentoo/snapshots/current/portage-2008.0.tar.bz2"

ready to chroot:
prepare:

Code:
#cp -L /etc/resolv.conf /mnt/gentoo/etc/

# mount -o bind /dev /mnt/gentoo/dev


now chroot

Code:
# chroot /mnt/gentoo /bin/bash
#env-update && source /etc/profile


update the tree

Code:
#emerge --sync


Change profile:
Code:
#emerge -av eselect

Kernel configurations:

check date:
Code:
#date


install sources:
Code:
#emerge -av gentoo-sources


check where does it point:
Code:
ls -l /usr/src/linux


configure it:
Code:
#make menuconfig

Compile the kernel:
N:S
The option that needs attention the most is cpu, the rest can be re-compiled later on.
We need up en running VM asap.
Code:
Processor type and features --->


Check if modules are built:
Code:
#find /lib/modules/<tab to get kernel version>


Code:
#make && make modules_install
#cp arc/i386/boot/bzImage /boot/kernel.img


System Configurations:
fstab:
    #rm /etc/fstab

Code:
#nano -w /etc/fstab

Quote:
# <fs> <mountpoint> <type> <opts> <dump/pass>

/dev/hda5 /boot ext3 defaults 1 2
/dev/hda6 / reiserfs defaults 0 1
/dev/hda7 /home ext3 defaults 1 2


Password
Code:
#passwd


Change the clock to local in /etc/conf.d/clock

System tools
Code:
#emerge -av pciutils syslog-ng vixie-cron reiserfsprogs slocate dhcpcd \
gentoolkit grub\
&& rc-update add syslog-ng default && rc-update add vixie-cron default



Configure grub.conf:
Code:
#grub --no-floppy

Quote:
grub> root (hd0,4) (Specify where your /boot partition resides)
grub> setup (hd0) (Install GRUB in the MBR)
grub> quit (Exit the GRUB shell)


grub.conf
Quote:

default 0
timeout 30

#splash image to spice things up
splashimage=(hd0,4)/boot/grub/splash.xpm.gz

#booting Gentoo linux
title=Gentoo Linux
root (hd0,4) #position of the kernel image in the boot partition ofcoz /dev/sda8
kernel /boot/kernel.img root=/dev/hda6 video=vesafb:mtrr:3,ywrap,vga=0x31B

Create a user:
Code:
#useradd -m -G users,wheel,audio -s /bin/bash john
#passwd user john


Finalize:
Code:
rm stage**
rm portage**



/************************************************************************/


Self-remarks:
-Video mode isnt correct, but you can pick up from the list en bootup process will continue
-Go to network and change the ethernet controller to intel/PRO/1000 works with NAT.Probably the other works too,but havent checked them.
-Ping doesnt working on guest, even though guest connected to the internet.Probably known issue with VB.
-You can set bridge which seemed like I need more time on it, never worked with it before.Probably next move for me

Leftovers:
Code:
emerge -av virtualbox-additions

Please leave critics or tips on the thread..ill check it again tomorrow going for wkn now :)

Because its behind NAT. So you cannot connect to virtual machine.

I would like to know howto bridge networking for VB. Whole instalation is in handbook.
