I am trying to setup mac address for a domU however everytime i start the domain, the mac address comes up as FE:FF:FF:FF:FF:FF. Here is the config file : kernel = "/boot/vmlinuz-2.6-xen" memory = 32 name = "vm01" nics = 1 vif = [''mac=AA:00:00:18:98:FB, bridge=xenbr0''] extra="selinux=0" disk = [''file:/root/xen/centos.4-2.img,sda1,w'', ''file:/root/xen/centos.swap,sda2,w''] root = "/dev/sda1 ro" No matter what mac i specify it comes up as FE:FF:FF:FF:FF:FF. Any help would be appreciated. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Have you ever tried using a valid header? A valid header is one used by a manufacturer, such as: "00:02:3F"; "00:02:2A" and so on. -- Eduardo Costa Lisboa _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The ones that change are the last three. A friend of mine told to use a valid header, not any random one, just to make sure the MAC address will be accepted by Xen. But I don''t know how Xen handles that, though. -- Eduardo Costa Lisboa _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Thanks for the explanation. Appreciate it.

HI, Did default install of Xen 3.0, ran updates to get latest kernel and other updates from YOU servers. When I boot with Xen kernel I have no internet access at all. Changed NIC to static address after using DHCP, which still works. ADSL Router acts as default gateway and DHCP Server. I have not created any virtual machines yet, just installed packages ! I cannot even ping router, what have I missed ? Cheers _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

All addresses starting with "FE:FD" can be used for what ever purpose you like. Don''t just grab some arbitary "valid" as the real network card might somewhen show up in your network. Keep in mind that MAC addresses must be unique. -- Goetz Bock (c) 2006 as blacknet.de - Munich - Germany /"\ IT Consultant Creative Commons secure mobile Linux everNETting \ / X ASCII Ribbon Campaign against HTML email & microsoft attachments / \ _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I had problems with our network switches (cisco) to use mac adresses which don''t start with a ''00''. I think this is related to broadcast protocol. regards BTW: We now transform the ip adress to an mac address so that we are sure that the xen machine interfaces have unique mac adresses. this mac adress range was used only in exotic network cards we don''t use. look: http://standards.ieee.org/regauth/oui/oui.txt On Mon, 2006-01-02 at 12:22 +0100, Goetz Bock wrote:> > On Fri, Dec 30 ''05 at 12:48, Anand wrote: > > I am trying to setup mac address for a domU however everytime i start the > > domain, the mac address comes up as FE:FF:FF:FF:FF:FF. > > > > ... > > > > vif = [''mac=AA:00:00:18:98:FB, bridge=xenbr0''] > > There is a range of MAC addresses reserved for personal use.
