[PVE-User] IPv6 issues after last update

I tested the new kernel. Some VMs seemed to have IPv6 connectivity (e1000). On one (linux,virtio) I had incoming connectivity after pinging the requesting system from the VM. CTs have no IPv6 connectivity.

On our cluster I switched back (rebooted) to kernel 2.6.32-34 (replacing -37 with -34 in /boot/grub/grub.cfg) and one node I upgraded to kernel 3.10. Both configuration give me IPv6.
