== Installing Ubuntu 10.04 LTS (Lucid Lynx) Xen PV guest using the Ubuntu text installer == |
|||
Ubuntu 10.04 can be installed as Xen PV guest using the default text-based installer included in the Ubuntu distribution. |
|||
First create a new LVM volume to store the guest virtual disk: |
|||
<pre> |
|||
[root@f13 ~]# lvcreate -nubuntu01 -L20G /dev/vg_f13 |
|||
Logical volume "ubuntu01" created |
|||
</pre> |
|||
Then download the official Ubuntu Xen guest configuration file: |
|||
<pre> |
|||
[root@f13 ubuntu]# wget http://fi.archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/xen/xm-debian.cfg |
|||

|||
</pre> |
|||
And rename it to "ubuntu01.cfg": |
|||
<pre> |
|||
[root@f13 ubuntu]# mv xm-debian.cfg ubuntu01.cfg |
|||
[root@f13 ubuntu]# |
|||
</pre> |
|||
Then edit "ubuntu01.cfg" with your favourite text editor and make it look like this (among other stuff in it): |
|||
<pre> |
|||
memory = 1024 |
|||
name = "ubuntu01" |
|||
vcpus = 1 |
|||
vif = ['mac=00:16:36:64:3d:f3,bridge=virbr0'] |
|||
disk = ['phy:vg_f13/ubuntu01,xvda,w'] |
|||
</pre> |
|||
Modify the mac address to be unique. |
|||
Then find a line in "ubuntu01.cfg" that says "bootloader=pygrub" and add proper path ("/usr/bin/pygrub") to it: |
|||
<pre> |
|||
if not xm_vars.env.get('install'): |
|||
bootloader="/usr/bin/pygrub" |
|||
else: |
|||
</pre> |
|||
Already modified configuration file is available as a reference from: http://pasik.reaktio.net/fedora/f13xen4tutorial/ubuntu01.cfg . |
|||
Then start the Ubuntu installer: |
|||
<pre> |
|||
xm create -f ubuntu01.cfg -c install=true |
|||
install-kernel="http://fi.archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/xen/vmlinuz" |
|||
install-ramdisk="http://fi.archive.ubuntu.com/ubuntu/dists/lucid/main/installer-amd64/current/images/netboot/xen/initrd.gz" |
|||
install-mirror="http://fi.archive.ubuntu.com/ubuntu" |
|||
</pre> |
|||
All of the above command needs to be on a single line. Replace the mirror site URLs with your local mirror. |
|||
Ubuntu 10.04 text installer starts: |
|||

|||
Install as usual. Choose DHCP for networking. |
|||

http://pasik.reaktio.net/fedora/f13xen4tutorial/ubuntu04.png |
|||
http://pasik.reaktio.net/fedora/f13xen4tutorial/ubuntu05.png |
|||
When the installation finishes the Ubuntu guest VM will shut down. |
|||
After installation you can start the Ubuntu guest like this: |
|||
<pre> |
|||
xm create -f ubuntu01.cfg -c |
|||
</pre> |
|||
First you'll see the pygrub menu which allows you to choose which Ubuntu kernel to boot, and then you'll get to the normal Xen PV guest text console and see the Ubuntu kernel booting. You can exit from the console by pressing ctrl+] or ctrl+5. |
