Dom0 Installation on Debian

This parameters were made for the Xen installation on Linux Debian over Intel machines or AMD 64 bits.

1) Install the adecuate software to enable it

 apt-get install xen-hypervisor-4.1-amd64 xen-tools xen-utils-4.1 xen-linux-system-amd64 

Debian autoconfigurates grub in order to use the Xen hypervisor for booting the next time

2) Reboot the machine

 reboot 

3) Check if the machine has the dom0 kernel of Xen

 uname -srm 

You have to see somethimg like this

Linux 3.2.0-4-amd64 x86_64

Also, you can see if dom0 is running by running the following command:

 xm list 

And the output will be

File: ..

        Name                                        ID   Mem VCPUs      State   Time(s)
        Domain-0                                     0  7926     8     r-----     20.0

4) Edit the /etc/xen/xend-config.sxp file and uncomment the follwing lines

File: /etc/xen/xend-config.sxp

        (network-script 'network-bridge netdev=eth0')
        (vif-script vif-bridge)

NOTE:

 Reboot the daemon before doing any change on this file

5) If you are using images on files, edit /etc/modules and change the "loop" module line in order to look like this:

File: /etc/modules

        loop max_loop=64

-CREATING IMAGES
-) Edit the /etc/xen-tools/xen-tools.conf file and put the configuration you like to. Example:
-{{File|/etc/xen-tools/xen-tools.conf|<pre><nowiki>
-        dir = /home/xen
-        install-method = debootstrap
-        size   = 4Gb      # Disk image size.
-        memory = 1024Mb    # Memory size
-        swap   = 1024Mb    # Swap size
-        fs     = ext3     # use the EXT3 filesystem for the disk image.
-        dist   = lenny     # Default distribution to install.
-        image  = sparse   # Specify sparse vs. full disk images.
-        kernel      = /boot/vmlinuz-`uname -r`
-        initrd      = /boot/initrd.img-`uname -r`
-        mirror = http://ftp.us.debian.org/debian/
-        ext3_options   = noatime,nodiratime,errors=remount-ro
-        gateway   = 192.168.100.1
-        netmask   = 255.255.255.0
-        broadcast = 192.168.100.255
-        passwd = 1
-</nowiki></pre>}}
-) Generate the image by using the following command.
-{{Command|<nowiki> xen-create-image --hostname=vm1.ve   --ip=192.168.100.80 --arch=amd64 --role=udev </nowiki>}}
-NOTE: The last script does not take on count some details, is necessary to fix them
-) Edit the /etc/xen/vm1.cfg file and modify the following lines for looking like this
-{{File|/etc/xen/vm1.ve.cfg|<pre><nowiki>
-        root = '/dev/sda2 ro console=/dev/hvc0'
-        vif  = [ 'bridge=eth0' ]
-</nowiki></pre>}}
-) Mount the image
-{{Command|<nowiki> mount -o loop /home/xen/domains/vm1.ve/disk.img /mnt </nowiki>}}
-) Edit the file /mnt/etc/inittab and change the line
-{{File|/mnt/etc/inittab|<pre><nowiki>
-:2345:respawn:/sbin/getty 38400 tty1
-</nowiki></pre>}}
-For it to look like this
-{{File|/mnt/etc/inittab|<pre><nowiki>

-) Edit the /mnt/etc/securetty file and add to the end of the line
-{{File|/mnt/etc/securetty|<pre><nowiki>
-        hvc0
-</nowiki></pre>}}
-) For booting the virtual machine run the following command:
-{{Command|<nowiki> xm create -c /etc/xen/vm1.platino.gov.ve.cfg </nowiki>}}
