Title:
  Multicast snooping on bridge breaks ICMP6 neighbor solicitation for
  KVM guests

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 3.13.0-24.46-generic 3.13.9 seems to be affected by the same
  bug as described here: http://patchwork.ozlabs.org/patch/326048/

  The suggested workaround (echo 0 > /sys/class/net/br0/bridge/multicast_snooping) solves IPv6-problems for KVM guests.
