Create cfg file for your YubiRadius DomU

In this post which is part of the series on how to import YubiRadius, a Free Radius appliance implementing OTP validation, into Xen Open source Hypervisor, we will finally create the .cfg file needed by the Hypervisor to create the virtual machine and boot it

As we saw earlier most of the work is already been done by the Xen.tools, which would already have created the cfg file (more…)

Modify Yubiradius image to boot in Xen

In this post which is part of the series on how to import YubiRadius, a Free Radius appliance implementing OTP validation, into Xen Open source Hypervisor, we will modify the image we have built in order to have all the bits and pieces to correctly boot under Xen Hypervisor environment as a paravirtual domain
The image we created in the previous post would not boot as a Xen paravirtual host, but it would (eventually) boot in a fully virtualized domain. It would be extremely inefficient (more…)

Build the Xen usable .img file

In this post which is part of the series on how to import YubiRadius, a Free Radius appliance implementing OTP validation, into Xen Open source Hypervisor, we will build an .img file containing a filesystem, mount it and then copy the Virtual Appliance files into it
The first step consist in creating a file of the proper size with

dd if=/dev/zero of=/workdir/empty.img bs=516096c count=#cyl

This statement sets (more…)

Extract YubiRadius from VMware image

In this post which is part of the series on how to import YubiRadius, a Free Radius appliance implementing OTP validation, into Xen Open source Hypervisor, we will extract the files from the VMware image and build a .tar file to eventually unpack it in a DomU .img

Yubico distributes its YubiRadius appliance in 2 formats: OVF and VMware. I was able to extract the appliance (more…)

Building a functional DomU with XEN

This post is part of a series of posts on how to import YubiRadius, a Free Radius appliance implementing OTP validation, into Xen Open source Hypervisor.
This first step in our quest to build our authentication server, actually has little to to with YubiRadius but a lot with running a para-virtual guest domain. We will then use the resulting (more…)
