Title:
  to determine ovs version are not using rootwrap

Status in neutron:
  Expired

Bug description:
  Hello,

  Looks like if using neutron in xenserver (neutron-plugin-openvswitch-
  agent in domU) than ovs and kernel version check occurs in domU
  without rootwrap, so it check domU version but should XenServer.
