[Xen-users] Xen dom0 gentoo filesystem

[Anton Titov <a.titov@xxxxxxx>]

Hello,

after seeing some discussions about creating a dom0 debian image as a 
gentoo fan, I've decided to make a gentoo dom0 image, and here it goes:
http://xen.titov.net/gentoo-xen-dom0-i686.tar.bz2
md5sum:
e0304b360d166dfdbc4b4a5ecd4157e2
Instalation instructions:

Boot some LiveCD, gentoo minimal LiveCD is a good choice, as it is only 
60Mb:
http://gentoo.mirrors.tds.net/gentoo/releases/x86/2005.0/installcd/install-x86-minimal-2005.0.iso

after booting LiveCD, partition your hard drive (don't make a boot 
partition) with:
fdisk /dev/YOUR_DRIVE

(optionally, but prefferably) create and activate swap with:
mkswap /dev/YOUR_DRIVES_SWAP
swapon /dev/YOUR_DRIVES_SWAP

create root filesystem with:
mkfs.reiserfs /dev/YOUR_DRIVES_ROOT
or mkfs.ext3 /dev/YOUR_DRIVES_ROOT
or whatever filesystem you prefer (you have kernel support and tools for 
reiserfs, ext3, ext2, jfs, xfs)
mount this partiton on /mnt/gentoo (yes, exactly there):
mkdir /mnt/gentoo  (you have it if you're with Gentoo LiveCD)
mount /dev/YOUR_DRIVES_ROOT /mnt/gentoo

configure your network (if you have DHCP server in the network, the 
chances are, that you got an IP from there):
ifconfig IP netmask NETMASK
route add default gw YOUR_GATEWAY
echo "nameserver YOUR_NAMESERVER" > /etc/resolv.conf

then cd into /mnt/gentoo and download gentoo-xen-dom0-i686.tar.bz2:
cd /mnt/gentoo
wget http://xen.titov.net/gentoo-xen-dom0-i686.tar.bz2

extract it with:
tar -xjpf gentoo-xen-dom0-i686.tar.bz2

run
./root/install

it will ask you for root password you want to set to the new dom0 (if 
you fail to change your password, e.g. press Enter 2 times,
your root will be "rootpass").

if the drive, you're installing on is not the one, from which the 
computer will boot use:
./root/install /dev/hda

where /dev/hda is the device, where grub will be installed

at this point you're ready ;)

But you may (actually should) want to change some more things:
chroot to the new system with:
chroot /mnt/gentoo

you have vi (symlink to vim) and pico (symlink to nano) editors btw

check if /etc/fstab, /etc/conf.d/net and /etc/resolv.conf files look OK 
for you.
edit /boot/grub/grub.conf and change dom0_mem, which is 128Mb by default

adjust your timezone with (unless you're in Sofia, Bulgaria):
ln -sf /usr/share/zoneinfo/FIND_YOUR_TIMEZONE /etc/localtime

set the hostname:
echo YOUR_HOSTNAME > /etc/hostname

you can do some more complex stuff here, but if you want to compile 
something, execute:
env-update
source /etc/profile
before that

now exit
umount
and reboot

/usr/portage/ directory is empty in the image, to save some space, so 
before installing any gentoo packagesh you should
emerge sync

the following gentoo packages are installed on the server:
sys-fs/lvm2
net-misc/curl
sys-fs/xfsprogs
app-admin/logrotate
sys-fs/jfsutils
net-misc/dhcpcd
sys-kernel/genkernel
sys-process/vixie-cron
app-editors/nano
net-firewall/iptables
sys-apps/coldplug
sys-fs/reiserfsprogs
app-admin/syslog-ng
sys-kernel/linux-headers
sys-apps/iproute2
sys-boot/grub
dev-python/twisted
sys-apps/hotplug
app-editors/vim
sys-libs/glibc

Kernel and binaries are compiled for i686, so it will not run on very 
old hardware (will run on pentiumpro+, athlon+).
