Hi All, I''m using opensuse 10.0, with Xen3.0 7398, and I''m having real trouble with my domU interface names. Whenever I change the networking configuration for the domU in the xen config file for that dom, the ethX in domU increments. I''m not doing anything special, just a standard bridged interface, and I''ll add it does work correctly - bridging out it''s vif etc. But I can''t have the eth interface changing. Currently my domU is up to eth7. I just want it to be eth0 like any normal [real] linux host, and stay that way! How is this all controlled in xen? Many thanks, Jonathan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

To return the first eth interface on the domU to eth0, you have to go into yast2, system, edit /etc/sysconfig and under Network -> Hardware -> Config, change Force_Peristent_Names to no. If you have multiple interfaces, you may want to put it back to yes once you have things the way you like them.> > How is this all controlled in xen? >That part I''m not as sure about, but to the best of my knowledge, it just prestents the int to the domU. The problem may be that messing with the config causes Xen to present a different MAC or other option to the domU, causing it to show up as a new interface thanks to the above udev setting. This all assumes that you''re running SUSE in the domU as well, but I''m sure that other distro''s have similar settings... hth, Jeff _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
