Hello Julian
CARP with this kernel in other environment does work fine.
The issue is that carp interface never goes MASTER, it stay in INIT state w/out
going into MASTER state.
The error we see on dmesg is:  ifa_del_loopback_route : deletion failed: 48.

There is no block on MAC-ADDRESSES on Hyper-v, no firewall, nothing.

We have tried with de interface (lelacy) and hn interface: same issue.

this is the hn interface:
hn0: <Synthetic Network Interface> on vmbus0

this is the ifconfig output:

hn0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 
1500
        options=18<VLAN_MTU,VLAN_HWTAGGING>
        ether 00:15:5d:2c:11:21

        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
        carp: INIT vhid 1 advbase 1 advskew 0

In attach I provide you full dmesg output

I can provide you an ssh access to this freebsd virtual machine, no problem at 
all.

Googling around we find many people facing the same issue (CARP on Hyper-v),
none was able to provide a solution in forums or mailing lists.

Looking forward to hear from you.

Best Regards
