Hi, In domU''s config file, I specify the name of the network interfaces, like: vif = [ ''vifname=x17.162, mac=00:16:3E:00:01:62,bridge=xenbr0'' ] When I create a PVM domU, the interface name is right. When I create a HVM domU, there will be a additional network interface named "tapN". How to know tap0 related to which domU? Or how to avoid the tapN interfaces like PVM? I use mrtg to monitor domU''s network usage. Xen version is 3.2.1 Thanks! _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
