Will CDRouter work with Xen-based virtualization kernels?

No. CDRouter must be run on non Xen-based kernels. Xen is sometimes installed as the default kernel on certain Fedora installations. As a result, CDRouter will not function properly on these systems until the machine is rebooted into a standard non Xen-based kernel.

There are two ways to alleviate this problem. The first and recommended solution is to modify the boot loader configuration to select a different default kernel. This will force the machine to boot a non Xen-based kernel each time it is restarted. To do this, simply edit the grub configuration file and select a different default kernel:

# vi /boot/grub/grub.conf

Note: kernels are indexed starting with 0 in the grub.conf file. To change the default kernel simply modify the 'default' field to point to a different kernel in the list of available kernels.

The second approach is to remove Xen entirely from the machine:

# yum remove xen

# yum remove xen-kernel
