Install Gentoo on VDS with Virtuozzo Virtualization

A little over a year ago, I started renting VDS from a company that uses Parallels Virtuozzo Containers with a very limited set of operating systems (Debian, Fedora, Ubuntu, Suse, CentOS) for virtualization . Of the entire list to the soul, nothing is special, but still I chose Debian, which I had to endure until recently. This moment is finding a methodology for installing Gentoo on VDS with this type of virtualization .

So let's get started

The first thing that would do well is to do a back-up of existing data, if it is of any value. This is done in the VZPP panel at yourserver_address : 4643 /. Then in the same panel we put VDS into recovery mode and after successful transfer we go through SSH to your VDS. The old file system in recovery mode lies in / repair. First, copy the mtab file from there:

cp /repair/etc/mtab /root/mtab.old

If there is any data in the old FS that should be transferred to the new system, we do with Gentoo:

cd /repair
mkdir old
for i in *; do if test old != $i; then mv $i old/; fi; done

If there is no important data, then we just erase everything:

cd /repair
rm -rf *

If suddenly / repair is read-only (I had OK, but the source mentions what happens sometimes), then before transferring / deleting we do:

mount -o remount,rw /repair

Now you are ready to download Gentoo:

wget http://mirror.yandex.ru/gentoo-distfiles/releases/x86/current-stage3/stage3-i686-20101019.tar.bz2
wget http://mirror.yandex.ru/gentoo-distfiles/snapshots/portage-latest.tar.bz2
tar xvjpf stage3-*.tar.bz2
tar xvjf portage-*.tar.bz2 -C /repair/usr
rm stage3-*.tar.bz2 portage-*.tar.bz2

Copy the DNS settings and return mtab to its place:

cp /etc/resolv.conf /repair/etc/
cp /root/mtab.old /repair/etc/mtab

Everything is ready for chroot in Gentoo:

mount -t proc proc /repair/proc/
mount -o bind /dev /repair/dev
chroot /repair

Immediately change the root password:

passwd

The new password will be valid not only for VDS, but also for the control panel. I also copied my key for SSH from the old FS. For download, baselayout + openrc will be used, which must be unmasked and installed (baselayout will pull openrc along with it):

echo "sys-apps/baselayout ~x86" >> /etc/portage/package.keywords
echo "sys-apps/openrc ~x86" >> /etc/portage/package.keywords
emerge baselayout

Now configure the network:

emerge iproute2
cd /etc/init.d
rm net.eth0
ln -s net.lo net.venet0
rc-update add net.venet0 default

Also add the network configuration to /etc/conf.d/net:

config_venet0=("87.118.x.z/24" "87.118.y.z/24")
routes_venet0=("191.255.255.0/24 scope link" "default via 191.255.255.1")

And add sshd to autorun:

rc-update add sshd default

According to my personal observations, the / etc / network / interfaces file is also necessary for the VDS to start normally (I previously had Debian, maybe the name of the file will be different for other distributions). Virtuozzo is apparently trying to write the current network configuration into it, and if it is not possible to run VDS, it ends in an error. So that:

mkdir /etc/network
touch /etc/network/interfaces

Now you can finally try to reboot ...
