Hi all, i asked this question a while ago and it relates to : http://lists.xen.org/archives/html/xen-devel/2011-01/msg01427.html http://lists.xen.org/archives/html/xen-devel/2012-10/msg01778.html I have patched my unbuntu 12.04 kernel (3.2.0-33-generic) xen-netback module as described in the post such that i can now change the mac address and vif: vif9.0 Link encap:Ethernet HWaddr 00:16:3e:ff:ff:fe inet addr:10.0.1.1 Bcast:10.0.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:32 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) However, after about a minute the IP and MAC revert the their default values. This is most annoying, and any ideas or help would be amazing! Thanks Paul _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
