I am using the same build as you:

# freebsd-version

And my Windows 10 guest has no issues booting and staying up.  You bhyve
command looks fine so there is probably something else happening.

What happens if you include the -w switch?

            Bug ID: 240647
           Summary: bhyve cannot properly use Windows (system restarts
           Product: Base System
           Version: 12.0-RELEASE
          Hardware: Any
                OS: Any
            Status: New

I've got an issue with using Windows (7/10 or even Server version) as a
client due to auto-restart of the system. I cannot even log in because
system restarts infinitely, seen at console on 5900 port.

Generally, I'm able to boot from CD/DVD (iso file). I can install Windows.
But after installation, the system loads and I can see logon screen. After
half a minute or minute system shuts down and that's all.
I was trying to run ready and working system from the another machine and
it's the same.

I tried this solution (Windows option change)


without success.
In this case I can change logon type to Safe mode, but after restart and
loading the system, the issue keeps the same.

I was trying on diffrent partitions with different hard drives.
I was changing number of CPU nad RAM (on bhyve).
I disconnected virtual network card network from bhyve command as well.

FreeBSD 12.0-RELEASE-p10 amd64

# bhyve -c 4 -m 8G -H \
-s 0,hostbridge \
-s 3,ahci-hd,/data/vm12.img,sectorsize=512 \ -s 10,virtio-net,tap1 \ -s
29,fbuf,tcp=,wait \ -s 30,xhci,tablet \ -s 31,lpc -l
