Hello everyone, I'm new to the list and I'm exploring Xen 4.4.0 for a project I'm working on. One of the requirements we have is that when we add a new network interface no reboot from the dom0 should be done. The client should be able to reboot from domU when they decide without loosing any of the attached network interfaces. As I understand, to make this changes persistent, the interface configuration should be added to the domU config file in /etc/xen/<guest-vm>.cfg The issues I'm getting are the following: 1- "xl network-attach" command correctly attaches the interface, but after the reboot from domU the interface is lost 2- Adding the interface to the configuration file will also work, but it requires a reboot of the domU from dom0 3- Rebooting from domU will in fact reboot the vm but the configuration file is not reloaded. The same issues are present when I try a "network-detach". I'm lost here, not sure where to look. I had tried with an old xen 4.1 setup and the hotplugged interfaces persists after reboot. My setup is: domU: debian wheezy 64 bits dom0: Ubuntu 14.04 with xen packages from repositories dom0: Debian Wheezy 64 bits with xen compiled from source Can someone give me a clue? Does this happens to you? I this the expected behaviour? Thanks in advance Jorge
