bhyve vm and virtio-console

Hi,
I am trying to configure bhyve vm with support of virtio-console, the 
following option is added to bhyve command line

*-s 3,virtio-console,port1=/test/console.sock

*However when trying to connect to socket with socat trere are no 
input/ouptut is observed.

Has virtio-console ever worked ?

Please advise.
