Comments on Installing Xen On An Ubuntu 8.04 (Hardy Heron) Server From The Ubuntu Repositories

It's not necessary to download the separate package any more.  There is a package in the hardy-proposed repository that works.

To use this package

echo "deb http://lu.archive.ubuntu.com/ubuntu/ hardy-proposed main universe" >> /etc/apt/sources.list
apt-get update
aptitude install linux-image-2.6.24-17-xen

This is no longer required - the updated kernel modules have been moved to the main repositories.

All that is required is to install ubuntu-xen-server, then move on to "vi /etc/modules"

Note that I found the "mv /lib/tls /lib/tls.disabled" step redundant, as the /lib/tls directory is not present (AMD64 installation).

Thanks for a great guide!

I have issues with netwoking on machine with Xen kernel. WHile i can ping and access everything normally on LAN it cant go out to Internet for some reason.

 here is ifconfig output

And thats what ping says:

Ideas? When i switch back to reguar kernel it all works fine. Network is DHCP enabled.

I have the exact same problem.  Has anyone found a fix for this yet?

I had similar problem. It was routing basically. You need to configure eth0 as usual, and peth0 should be up but excluded from routing (if you use DHCP it would make it included in routing). One of simplest ways to achieve it is to set peth0 as ipv4ll.

Hi grw:

Would you please give some details about how to config eth0 and peth0? Such as instructions or examples? I am new to Linux network and Xen.

Thanks.

Remove the network-manager package. apt-get remove network-manager

I had the same problem and eventually found it was my iptables in dom0 that was the problem...

<code> #I think we have an iptables problem, so first of all write out the old table.
iptables-save > /etc/iptables.check.this
nano /etc/iptables.check.this</code>

 If there is a line in there that looks like...

<code>-A FORWARD -j REJECT --reject-with icmp-port-unreachable</code>

then remove it, save the file, and load it into iptables using...

<code>iptables-restore < /etc/iptables.check.this</code>

If this clears it you may want to save this to your boot-up iptables, on my system I used...

Ok guys i found an easy way around for my previous post!

The bug is actualy in the xen-tools config file! When you edit it just make sure that you edit the line saing 'reiser_options=defaults' to 'reiserfs_options=defaults' in /etc/xen-tools/xen-tools.conf. That will set the proper options in the fstab of the VMachine.

You can change 'defaults' to whatever options for reiserfs you like. In my case 'notail,relatime' works fine!!

I'm using ubuntu 10.04 64-bit.

when I try 'apt-get install ubuntu-xen-server' I get the following error:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  ubuntu-xen-server: Depends: xen-tools but it is not installable
E: Broken packages
 

If xen-tools isn't installable then is this how-to out of date?

Excuse me. when I installed xen kernel and rebooted the system I chose it from grub menu list and it seemed it was working but after writing some output on screen, I did not see anything on screen and it was kind of crash. The computer did not respond to any other key and I had to reset it. what is the problem. I have Linux 8.1
