bhyve bhyve guest windows10 can not type capital letters

[log]

When I try to type capital letters on bhyve guest windows10 I got messages "Unhandled ps2 keyboard keysym 0xffe5",
and Only lowercase letters are printed.

My script start windows10 is as follows:

#!/bin/sh
bhyve -c 1 -m 2G -w -H 
-s 0,hostbridge \
-s 2,ahci-hd,/dev/zvol/zroot/win10disk1 \
-s 3,virtio-net,tap2 \
