The Funtoo Linux project has transitioned to "Hobby Mode" and this wiki is now read-only.
Xen
Funtoo Xen Fun We are talking about Xen on Funtoo Linux and how to setup Xen virtualization properly. Especially, we are going to show you how much fun it is to work with Xen hosts and domU's and setting up a Funtoo Xen Server without general clicky GUI's or other frontends. This is true hardcore OS Xen setup especially for NOC server systems, headless servers, etc..
Funtoo Xen Server with paravirt funtoo domU
Assumptions We build a 64bit headless XEN hypervisor rockstable and rocket fast with a funtoo headless 64bit paravirt domU. We are not building Xen with pvgrub or hvm (which is kinda slow and overhead as long as you don't want to install Windoze).
Buiding Funtoo Xen Host Dom0
Most of the necessary steps are covered in the Installation Tutorial. We only do outline here the steps that are necessary to enjoy an easy and successful Dom0 setup or if something differs from the normal installation tutorial.
Please, open in a second tab the Installation Tutorial and follow in both carefully the next steps!
Basic Funtoo Xen Host Dom0 setup
I recommend you use only stable packages for the host dom0 !
Please consider the decision carefully. I can't stress out enough, you will avoid a lot of problems taking the stable distrib as dom0. The domU guests could be either unstable or hardened, as you wish! There comes the true fun part ;-) That's why I first edit my make.conf befor building anything!
Here is how I set up the system basics: Disk is /dev/sda
/dev/sda1 is our / partition ca 20GB ext4 /dev/sda2 is our swap partition ca 4GB /dev/sda3 holds the lvm volume group vgxen
I am using volume groups over raid - which I strongly advice to everybody.
Store of xen stuff:
/etc/xen/ --> xend configuration files /xen/configs/ --> my xen domU configuration files folder /xen/kernel/ --> my xen domU kernel folder /xen/disks/ --> my xen domU image files folder
Edit /etc/rc.conf and uncomment the line at the bottom for rc_sys
rc_sys="xen0"
Configure and Build Xen Dom0 Kernel
emerge gentoo-sources cd /usr/src/linux make menuconfig
These settings are current as of 3.2.1-gentoo-r2, other versions may vary:

- Don't forget to add the required drivers for your networking and sata cards
- If you use RAID, make sure to add the correct CONFIG_MD_RAID* entries to your config
make make modules_install
If you experience issues with connecting to the console ensure the module "xen_gntdev" (userspace grant access device driver) is loaded before the xenconsoled process is started (you may have to restart it after loading the module).
Configuring Grub
Work has been completed to automatically enable Xen Grub entries, so after you copy your dom0 kernel edit your /etc/boot.conf as follows:
"Funtoo on Xen" {
type xen
xenkernel xen.gz
xenparams loglvl=all guest_loglvl=all xsave=1 iommu=1 iommu_inclusive_mapping=1 dom0_max_vcpus=2 dom0_vcpus_pin dom0_mem=4096M
kernel kernel[-v]
params += quiet
}
To note a fiew things iommu is the paravirtualized instructions, if your motherboard or CPU does not support VT-d do not enable it. Xsave saves the supported CPU instruction sets, without it you're dom0 kernel may not boot. And finally dom0_vcpus_pin permanatly assigns cpu's to dom0, increasing performance.
Basic Networking with the Dom0
Funtoo Linux offers its own modular, template-based network configuration system. This system offers a lot of flexibility for configuring network interfaces, essentially serving as a "network interface construction kit."
There is given eth0 and eth1. We are going to set eth0 as the default interface to the outside world for now. eth1 will be part of a bridge (xenbr0) that is going to be used by various domU guests.
Construct the interfaces:
cd /etc/init.d/ ln -s netif.tmpl netif.xenbr0 ln -s netif.tmpl netif.extbr0 ln -s netif.tmpl netif.eth0 ln -s netif.tmpl netif.eth1 rc-update add netif.xenbr0 sysinit rc-update add netif.extbr0 sysinit
Make sure dhcpcd, eth0 and eth1 don't start at boot:
rc-update del dhcpcd sysinit rc-update del netif.eth0 sysinit rc-update del netif.eth1 sysinit
Configure the slave interfaces:
cd /etc/conf.d/ echo 'template="interface-noip"' > netif.eth0 echo 'template="interface-noip"' > netif.eth1
Then we are going to prepare the bridges.
nano netif.xenbr0
here we set the internal Xen bridge:
template="bridge" ipaddr="10.0.1.200/24" gateway="10.0.1.1" nameservers="10.0.1.1 10.0.1.2" domain="funtoo.org" slaves="netif.eth0"
Then we are setting up the external interface:
nano netif.extbr0
this is looking quiet similar, please watch out for the correct slave setting!
template="bridge" ipaddr="10.0.1.201/24" gateway="10.0.1.1" nameservers="10.0.1.1 10.0.1.2" domain="funtoo.org" slaves="netif.eth1"
This gives us the possibility to play around with various setups later, it's modular and easy to tweak and change.
Better you invoke with "rc" on the command line the openrc script and test if the network cards get initialized correctly.
Basic Networking with domU
The easiest way is to let Xen set up the networking. But if everything is up and running it is not possible to change the routings, etc. Letting Xen do the bridges will be obsolete in the near future. So this is not the recommended way anymore. As we already set up the bridges in the previous section it may be enough to comment everything network related. If not, just un-comment the last lines.
We edit the /etc/xen/xend-config.sxp
#### Xen config from maiwald.tk - Xen 4.x Network in bridge mode (logfile /var/log/xen/xend.log) (loglevel DEBUG) (xend-relocation-server no) (xend-relocation-hosts-allow '^localhost$ ^localhost\\.localdomain$') # The limit (in kilobytes) on the size of the console buffer (console-limit 1024) (dom0-min-mem 384) (enable-dom0-ballooning no) (total_available_memory 0) (dom0-cpus 0) (vncpasswd 'geheim') # let xen create the net # (network-script network-bridge) # (vif-script vif-bridge) # we create the net - new default in Xen 4 # #(network-script 'network-bridge netdev=eth0 bridge=xenbr0 vifnum=0') #(vif-script vif-bridge bridge=xenbr0)
Building the Funtoo Xen DomU Container
We are going to build the DomU now, preparing first from outside the domU.
create lvm volume or partition or image file
This is a stub, please help completing this guide here!
root # vgcreate vgxen /dev/sda3 root # lvcreate -L10G -n funtoo_root vgxen root # lvcreate -L1G -n funtoo_swap vgxen root # vgchange -a y root # mkfs.ext4 -L funtoo_root /dev/vgxen/funtoo_root root # mkswap -L funtoo_swap /dev/vgxen/funtoo_swap root # rc-update add lvm boot
Basic DomU System setup
mount domU lvm volume or physical partition or image file
root # mkdir /mnt/domu1 root # mount /dev/vgxen/funtoo_root /mnt/domu1 root # cd /mnt/domu1
get stage3
from a funtoo mirror near you, I suggest you look at the funtoo homepage
root # links http://www.funtoo.org/wiki/Download
Then choose a mirror near you ( I use Heanet in EU ) and look for the right stage3. I use XEON CPUs so I take the core2 distrib:
root # wget -cv http://ftp.heanet.ie/mirrors/funtoo/funtoo-stable/x86-64bit/core2_64/stage3-latest.tar.xz
Unfortunately I can't find md5sums or similar which is really unpleasant.
then get latest portage tree from the snapshots firectory
root # wget -cv http://ftp.heanet.ie/mirrors/funtoo/funtoo-stable/snapshots/portage-current.tar.xz
extract stage3
root # tar xpf stage3-current.tar.xz
extract portage
root # cd usr root # tar xf ../portage-current.tar.xz
Preparing the chroot environment
Editing the make.conf
copy /etc/make.conf from dom0 and adjust it
root # cp /etc/portage/make.conf /mnt/domu1/etc/
make sure to adjust MAKEOPTS to your assigned CPUs (rule of thumb cpu cores +1 - yes, even in XEN)
root # nano -w /mnt/domu1/etc/portage/make.conf
out there the MAKEOPTS variable in:
MAKEOPTS="-j2"
copy /etc/resolv.conf
root # cp -L /etc/resolv.conf /mnt/domu1/etc/
mount proc and dev
root # mount -t proc none /mnt/domu1/proc root # mount --rbind /dev /mnt/domu1/dev
Building Funtoo Xen Guest(s) DomU
Final DomU System setup
chroot
root # chroot /mnt/domu1 /bin/bash root # env-update root # source /etc/profile root # export PS1="(domU-chroot) $PS1"
sync portage
root # emerge --sync
set locales
root # nano -w /etc/locale.gen root # locale-gen
set your timezone
(choose your timezone in /usr/share/zoneinfo)
root # cp -L /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime
edit /etc/fstab (see also gentoo handbook as reference)
we assume that we name our root partition xvda1 and the swap partition xvda2 in our domU-xen-config (we will do that later)
root # nano -w /etc/fstab
/dev/xvda1 / ext4 noatime 0 1 /dev/xvda2 none swap sw 0 0 shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
Now comes the most important stuff
please just copy this into your terminal:
echo '

'> /etc/motd
We are using the echo instead of „emerge --moo „ as larry still moo's in gentoo'ish
So that's it - almost.
adding networking to the domU:
(domU-chroot) # cd /etc/init.d/ (domU-chroot) # ln -sf netif.tmpl netif.eth0 (domU-chroot) # rc-update add netif.eth0 * service netif.eth0 added to runlevel sysinit
Now we are ready to do the last setups
(domU-chroot) # emerge eix
After that I am feeling better now, I do the rest..
(domU-chroot) # eix-update
Reading Portage settings ..
Building database (/var/cache/eix) ..
[0] "gentoo" /usr/portage/ (cache: metadata-md5-or-flat)
Reading category 154|154 (100%) Finished
Applying masks ..
Calculating hash tables ..
Writing database file /var/cache/eix ..
Database contains 15729 packages in 154 categories.
(domU-chroot) # exit
exit
From here you have to decide how you want to run your domU: with unpriviledged users and sudo ? or with a root account enabled? as a webserver or firewall?
Me, personally, I always do install openssh server and just place my ssh keys in there. From there the steps differ.
(dom0-xen) # cp /root/.ssh/authorized_keys /mnt/domu1/root/.ssh/
Also, don't forget here to enable PubKeyAuth in your sshd_config in your domU and set PermitRootLogin to yes!
Double checking! Does your domU kernel uses modules or not? If you haven't built a monolitic kernel you should copy the modules from the dom0 to the domU now:
(dom0-xen) # mkdir /mnt/domu1/lib/modules (dom0-xen) # rsync -aP /lib/modules/2.6.38-xen-maiwald.tk-dom0 /mnt/domu1/lib/modules/
Ok, that's it from here..
Don't forget to clean up the mounts!
(dom0-xen) # cd (dom0-xen) # umount -l /mnt/domu1/proc (dom0-xen) # umount -l /mnt/domu1/dev (dom0-xen) # umount -l /mnt/domu1
That's it! ;-)
Booting the Xen DomU Guest
Ok, let's try the first boot of the newly created Xen DomU in Funtoo!
(dom0-xen) # cd /xen (dom0-xen) # xm create -c configs/funtoo.cfg
Huuuuiiiii......
Using config file "./configs/funtoo.cfg".

This is localhost.unknown_domain (Linux x86_64 2.6.38-xen-maiwald.tk-domU) 17:27:40
localhost login:
Finalizing the setup
Now we test if we can reach the DomU from our Desktop:
(2034)-~% ssh -lroot 217.x.x.211 The authenticity of host '217.x.x.211 (217.x.x.211)' can't be established. RSA key fingerprint is 22:e3:xxxxxxxx:b0:3c:xxxxx:d6:e5:c3. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '217.x.x.211' (RSA) to the list of known hosts. Enter passphrase for key '/home/mm/.ssh/id_rsa': localhost ~ # uname -a Linux localhost 2.6.38-xen-maiwald.tk-domU #4 SMP Wed Feb 8 17:30:33 CET 2012 x86_64 Intel(R) Xeon(R) CPU E3110 @ 3.00GHz GenuineIntel GNU/Linux localhost ~ #
All seems good for now.
Now switch back to the Funto Installation Tutorial and go on with setting up your new domU guest like a normal funtoo linux system!
Please consider to help supporting this Wiki with editing this page and keeping it current!
Funtoo is a perfect Xen Host and I can really recommend it to everybody as an alternative to .deb/.rpm Systems.
Have fun!
