is there a reason why my domU is getting eth1 as the network device instead of eth0? xen version: 3.03 dom0: Ubuntu 7.04 Server. domU: I created a template for the domU by creating a looback filesystem in an existing Ubuntu Server. I mounted it then Rsynced the contents of / to the mounted filesystem. I copied everything including /dev and /proc. what should i do to ensure that eth0 is created when i use the image? also how do i make sure that the mac address for the eth0 will be different each time i create a duplicate of the image file for a new domU? TIA, Tomoki _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The configuration for eth0 is tied to the MAC address of the card on that server, this MAC address won''t exist on your DomU and so your interface will be assigned as eth1. On your DomU, open the file /etc/udev/rules.d/30-net_persistent_names.rules. You probably have a rule something like the following for eth0: SUBSYSTEM=="net", ACTION=="add", SYSFS{address}=="00:aa:aa:aa:aa:aa", IMPORT="/lib/udev/rename_netiface %k eth0" Remove it and try restarting your Dom0. -- Mike Peters Web Site: http://www.ice2o.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Mike, thanx for your reply, unfortunately there was no /etc/udev/rules.d/30-net_persistent_names.rules file. I found /etc/iftab file instead which contained <snip> # This file assigns persistent names to network interfaces. # See iftab(5) for syntax. eth0 mac 00:aa:aa:aa:aa:aa arp 1 <snip> erasing that line fixed my problem. thanx for your help Tomoki On 7/30/07, mpeters@mpeters.f2s.com <mpeters@mpeters.f2s.com> wrote:> Quoting Tomoki Taniguchi <tomoki.taniguchi@gmail.com>: > > > is there a reason why my domU is getting eth1 as the network device > > instead of eth0? > > > > xen version: 3.03 > > dom0: Ubuntu 7.04 Server. > > > > domU: I created a template for the domU by creating a looback > > filesystem in an existing Ubuntu Server.
