    Hello everyone,

    I have some problem by using XEN kernel on Centos 5.x. I've tried to make XEN based vms on three of my dedis in a german DC and each time after the Xen kernel was installed, the mac address of eth0 has been changed to FE:FF:FF.FF.FF.FF and after reboot the server couldn't be reached via SSH. I found out this via KVM and manually reset the mac-address to the original. The question is how can I prevent this from happening without the help of KVM?

    Any help will be much appreciated

    You should add a mac address to the config file of your VM

    somewhere you defined:

    vif = [ 'ip=1.2.3.4,mac=00:01:02:03:04:05' ]

    Hi, many thanks for the nice reply. The problem started even before I created any VM. I simply used "yum groupinstall" to get the XEN kernel and changed the grub.conf to start with "0". After reboot, I found out that the eth0 has been changed to "FE:FF:FF.FF.FF.FF".
