No arp entry on vlan interface

    Details

      Description

      taken from openvz forum, see link below
      >Description of problem:
      When I upgrade from openv 7.0.6 to 7.0.6, I was unable to communicate from container to outside.
      I use vlan interface on HN :
      em1 -- br0 -- vlan18

      On previous releases, arp entry are created on any interfaces. Now, the arp entry is added only on virbr0 interface:

      apr -en
      Address HWtype HWaddress Flags Mask Iface
      ....
      192.168.18.239 * <from_interface> MP virbr0
      192.168.18.239 * <from_interface> MP vlan18
      ...

      And now

      apr -en
      Address HWtype HWaddress Flags Mask Iface
      ....
      192.168.18.239 * <from_interface> MP virbr0
      ...

      I found the filter on /usr/libexec/libvzctl/scripts/vz-functions line 642 (function vzgetnetdev) :

          [ -e "/sys/class/net/$dev/device" -o -e "/sys/class/net/$dev/bridge" ] || continue

      Can you change this line to enable vlan interfaces ?
