bhyve and CARP?

[dweimer]

I am considering setting up a bhyve virtual machine to run pfSense. Not 
too thrilled with the CPU heat on the PC Engines APU1D4 when under heavy 
load, but don't want to rely entirely on a VM. As I like still having 
internet if I would have to take my server offline for disk replacement 
or other issues, having web access to search for errors is a big plus. 
So in order to avoid spending money on a new piece of hardware I thought 
why not do a VM with CARP fail over to the physical. I am not finding 
much searching on FreeBSD byhve and CARP, I know its somewhat of an 
issue withing VMware on ESX making sure you enable the right options on 
the virtual switches and interfaces.

Enable promiscuous mode on the vSwitch
Enable "MAC Address changes"
Enable "Forged transmits"

Before I got started on the setup I was curious if anyone has done 
something similar, or know if this isn't possible on bhyve at the 
current version? I am running my system currently on 10.3-BETA3.
