to long interface names

Hi there

I've got an issue by creating HVM guests. My environment Ubuntu 17.04 with XEN 4.8 (xenproject) nova 7.1.0, libvirtd 2.5.0, openvswitch 2.6.1. So far OpenStack Ocata.. The issue by using linuxbridges with libvirt, libxenlight and nova is that the names of the virtual interfaces are to long. So brctl couldn't work with it. The issue with the to long names is only present by creating HVM guests. At last with PVM guests it works. Anyway is there a way to configure the max lengh of an virtual interface name?

cat /var/log/xen/xen-hotplug.log Error: argument "tap5b6d941e-50-emu" is wrong: "name" too long
