Sorry for delay.
Unfortunately the problem somewhere else. Depending on the FreeBSD revision
there is a different behavior except usual. E.g:
a) 10.1-RELEASE and 10-STABLE:
% kldload carp
% kldstat -m carp
Id Refs Name
486 1 carp
% /sbin/ifconfig vtnet0 vhid 1 advskew 100 pass navuhodonosor 192.168.1.210/24
state master alias
ifconfig: SIOCSVH: Invalid argument
b) On FreeBSD-current r276500M CARP IP is established for some seconds, then
vanishes:
% /sbin/ifconfig vtnet0 vhid 1 advskew 100 pass navuhodonosor 192.168.1.210/24
state master alias
% ifconfig vtnet0
vtnet0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu
1500
