--- Comment #3 from olivier@cochard.me ---
I=C2=A0beleive I've found the source of the problem in this message:

https://lists.freebsd.org/pipermail/svn-src-head/2014-January/055007.html

"It also does not handle multicast filter configuration when VTNET_FLAG_CTR=
L_RX
flag is not set.  If vtnet(4) does not support multicast filter, it shouldn=
't
announce IFF_MULTICAST. I wonder how vtnet(4) can work
with carp(4) given that its multicast handling is ignored."

If I understand correctly: Multicast support is totaly missing on the vtnet
drivers ?
