wsconscfg: Cannot open `/dev/ttyEcfg': Device not configured

[void <void%f-m.fm@localhost>]

Hi,

I'm running 10.1 amd64 as a vm guest on a bhyve (freebsd) host.
It uses 4x vCPU, 32GB vRAM & 32GB ffs2 disk (it presents to
netbsd as ffs2, but in freebsd it's a zvol).

The session is wrapped in tmux.

It boots and runs well. ssh into the vm works fine.
I notice in the console the following errors:

===
wsconscfg: Cannot open `/dev/ttyEcfg': Device not configured
wsconscfg: Cannot open `/dev/ttyEcfg': Device not configured
wsconscfg: Cannot open `/dev/ttyEcfg': Device not configured
wsconscfg: Cannot open `/dev/ttyEcfg': Device not configured
Keyboard wsconsctl: WSKBDIO_SETENCODING: Permission denied
===

Is there anything I can/could/should do about them?
