Following along a great debian-administration.org article, titled, “Debian Sid gets Xen 3.0″, I set up a minimal Debian Sarge AMD64 install from debian-31r0a-amd64-netinst.iso for use as a Xen development server. The full text of this post contains my step-by-step how-to on my successful installation.

I ran a default netinstall installation, selecting no additional software packages, and used the “multi-user workstation” partitioning scheme, which segregates the /, /usr, /var, /tmp, and /home partitions, with most of the disk using /home, where the Xen virtual machines will reside.

Bang the link below for my full notes!

shutdown -r now (just to be sure we have a good vanilla kernel)

Nice! The packages set up the init services, too:

Log in! To detach from xenconsoled:

Ctrl+]

And with minor changes (hostname, IP) to the above xen-create-image command, I can set up more VM’s for the rest of my IP space.

Hope this helps someone (and me to set up more)!
