Hi All,
This seems to be OK now. The problem was the misleading messages displayed by bhyve when the virtual machine is started. These messages followed this mail.
The real problem was that the two instructions to be executed at boot prompt of the OpenBSD OS ("set tty com0" and "stty com0 115200") have not
been typed. These two instructions indicate to the OpenBSD kernel to use a serial console.
The problem with these strange messages (the typography of the message has not been changed
in the log after this mail) is that one can think that the problem is coming
from the passthrough of the network cards by the hypervisor bhyve to the virtual machine.
Best regards
