Hi everyone, I switch my server from a xend/xm Xen install to a 4.1 xl Xen install. Therefore Xen does not create vif network interface when I launch xl create /etc/xen/my_server.cfg but does create vif network interface with the command xm create /etc/xen/my_server.cfg Here are sample configuration: nano /etc/xen/xl.conf vifscript="vif-bridge" nano /etc/xen/xend-config.sxp (network-script network-bridge) (vif-script vif-bridge) nano /etc/default/xen TOOLSTACK=xl Any idea ? I'm lost :-( Best Regards.
