CentOS DomU on Ubuntu 8.04 LTS Dom0

[atjensen11]

I have been following the tutorial referenced here.

http://www.howtoforge.com/create-cen...ntu-hardy-dom0

Now there are lots of typos and errors in the tutorial, but I managed to overcome them. Upon creating the CentOS DomU, I do get a login prompt and can login.

The first issue I had was that I couldn't get any updates or install packages. I thought it was a DNS issue. But after fixing that, I noticed I couldn't even ping.

Typing ifconfig at the command prompt, I noticed that eth0 has a MAC address, but no IP. I did follow the tutorial on specifying the IP. I also tried specifying it in the Xen config file for the DomU.

Regardless of which method I try, I get an error message upon starting the DomU that says another host already has claimed this IP address. I know for a fact that is not the case. I have changed the IP address too and no matter what I change it to, I get the same error message.

Any ideas of where to look next?

I haven't tried that tutorial, but I'd use xen-tools for creating guests. They also support creating CentOS guests.

[atjensen11]

I tried your suggestion tonight of using xen-tools. First, I looked under /usr/lib/xen-tools and saw two CentOS related directories: centos-4.d and centos-5.d.

So I assumed that when creating the DomU using xen-tools, I would use the parameter:

--dist=centos-5

However, the installation failed. Below is the sanitized result of the log file.

I get a similar error when trying a CentOS 4 DomU as well.

Please use rpmstrap instead of debootstrap (that tool is only for Debian/Ubuntu).

[atjensen11]

So I changed the --install-method parameter to be rpmstrap instead of the default debootstrap.

Now I receive the following error:

Installation method: rpmstrap
The following required binary for the installation was not found
        /usr/bin/rpmstrap
Done
System installation failed.  Aborting

I googled around and found many references to rpmstrap being broken in Gutsy. I am running the Hardy (8.04 LTS) server version.

I also did an apt-cache search for the rpmpackage, but nothing was found using the standard repositories. On the Ubuntu site, I could only find the package mentioned in the Gutsy and Gutsy-updates listings.

[falko]

If rpmstrap doesn't work, you can also use rinse. There's a rinse package for Hardy. Of course, you must configure xen-tools to use rinse instead of rpmstrap.

[atjensen11]

So I installed rinse and the dependency package rpm.

The xen-create-image command appeared to work great without any errors. However, when starting the DomU using the -c parameter to go into the console, a prompt appears requiring me to log in for Maintenance.

I don't know the default password. When the xen-create-image was running, it stated that there is no passwd command in the centos-5 package and so the password was not changed when the image was created.

Any suggestions?

What's in the xen-tools log?

[atjensen11]

Here is a snippet of the xen-tools log file for this DomU. Everything above this point was successful (creation of LVM on Dom0, IP addresses, etc.)
