Xen installing Centos 5 domU inside debian etch dom0 with xen-tools and rinse

At work I am just beginning the process of migrating from a hosted dedicated server to a Xen instance on a new server we have. Our dedicated server runs centos, and has WHM cpanel installed. So I figured it would be a good thing to have cpanel again as several people are familiar with it, and we do host a few random websites for people still. Cpanel does not support debian to my knowledge so Centos 5 sounds like the best way to go. Centos 5 is supported by a newer xen-tools package than what is provided in etch so I added /etc/apt/sources.list.d/xen-tools.list with the content

#
#  Steve Kemp's repository:  Etch
#
deb     http://apt.steve.org.uk/etch etch main non-free contrib
deb-src http://apt.steve.org.uk/etch etch main non-free contrib

Once that was done a simple aptitude update and aptitude dist-upgrade updated xen-tools to a newer version.
There is a new tool called rinse that can bootstrap rpm based distros like centos and fedora. Since I want a centos 5 domu I issue the xen-create-image with the following command

xen-create-image --hostname centos5_domU --ip 192.168.1.50 --install-method rinse  --force --dist centos-5 --arch=amd64

No errors with the command so everything looks ok, try booting the guest vm up with

xm create centos5_domU.cfg -c

uh oh, something went wrong, the domU would not finish booting checkout the output

Now what? Well we start debugging. I quickly tried creating a centos4 domU the same way, and it booted without issue. So there must be somethng wrong with the creation of the centos5 domU. Since its bootstrapped with rinse thats a good place to start.

A quick glance at man rinse show us how to use rinse by itself. So lets try bootstrapping a centos 5.

rinse --distribution centos-5 --directory=/tmp/centos-test --arch=amd64

and by looking at the rinse output
we can see that indeed our problem is bootstrapping with rinse.
…. and the debugging continues

  • Best way to get the root password over is to find another linux box (e.g. debian) with working root login,
    cat /etc/passwd and cat /etc/group, copy the root line.
    On your debian box, mount the main disk and cat >>/etc/passwd and paste working root profile.
    Do the same with the /etc/group.
    umount the disk and restart the VM.
    It works for me.
