The Perfect Xen 3.0.1 Setup For Debian - Page 3
3.2 Installing From The Sources
Run the following commands:
apt-get remove exim4 exim4-base lpr nfs-common portmap pidentd pcmcia-cs pppoe pppoeconf ppp pppconfig
apt-get install iproute bridge-utils python-twisted gcc-3.3 binutils make zlib1g-dev python-dev transfig bzip2 screen ssh debootstrap libcurl3-dev libncurses5-dev
3.2.1 Install Xen
Now download xen-3.0.1-src.tgz from http://www.xensource.com/products/downloads/dl_x30tarball_bt.html with BitTorrent and put it into the /usr/src directory. Then do the following:
cd /usr/src
tar -xvzf xen-3.0.1-src.tgz
cd xen-3.0.1/
make world
Now we compile a dom0 kernel:
cd linux-2.6.12-xen0
ARCH=xen
export ARCH
make oldconfig
make menuconfig
In the kernel comfiguration menu that shows up we enable quota, iptables and the dummy network driver as modules. This is where you enable these modules:
File systems --> [*] Quota support
<M> Old quota format support
<M> Quota format v2 support
Device Drivers ---> Networking support ---> <M> Dummy net driver support
Device Drivers ---> Networking support ---> Networking options ---> [*] Network packet filtering (replaces ipchains) ---> IP: Netfilter Configuration ---> <M> IP tables support (required for filtering/masq/NAT)
[*] means: build into the kernel statically.
<M> means: build as a kernel module.
Next we build and install the dom0 kernel:
cd ..
make
make install
Afterwards we compile a kernel for domU (the virtual machines):
cd linux-2.6.12-xenU
ARCH=xen
export ARCH
make oldconfig
make menuconfig
In the kernel comfiguration menu that shows up we have to enable quota and iptables as modules (it is important that they are modules. I could not get iptables to work in a virtual machine when I compiled it into the kernel statically!). This is where you enable these modules:
File systems --> [*] Quota support
<M> Old quota format support
<M> Quota format v2 support
Device Drivers ---> Networking support ---> Networking options ---> [*] Network packet filtering (replaces ipchains) ---> IP: Netfilter Configuration ---> <M> IP tables support (required for filtering/masq/NAT)
[*] means: build into the kernel statically.
<M> means: build as a kernel module.
After you have left the kernel configuration menu, do the following to build and install the domU kernel:
cd ..
make
make install
mv /lib/tls /lib/tls.disabled
Now Xen is installed. In order to start the Xen services at boot time, do the following:
update-rc.d xend defaults 20 21
update-rc.d xendomains defaults 21 20
3.2.2 Configure The Bootloader And Reboot
Next we add our new kernel to Grub, our bootloader. Edit /boot/grub/menu.lst, and before the line ### BEGIN AUTOMAGIC KERNELS LIST add the following stanza:
vi /boot/grub/menu.lst
title Xen 3.0.1 / XenLinux 2.6.12-xen0 |
Make sure that /dev/hda6 is your / partition. Keep in mind what I said about Grub and partitioning in chapter 1!
Now reboot the system:
shutdown -r now
At the boot prompt, Grub should now list Xen 3.0.1 / XenLinux 2.6.12-xen0 as the first kernel and boot it automatically. If your system comes up without problems, then everything is fine!
