Hello, We have configured xen 4.4.1 to use a custom hotplug script for network interfaces: On /etc/xen/xl.conf: vif.default.script="vif-custom" It works fine when creating a vm, when rebooting the vm, etc. But when I run 'xl network-attach' command it does not seems to load default settings: bridge interface and script default values are ignored and should be manually specified. Is this a known bug? A desired behaviour? Is there any workaround for this issue? Greetings, Jorge
