Hi All,
This seems to be OK now. The problem was the misleading messages disp=
layed by bhyve when the virtual machine is started. These messages followe=
d this mail.
The real problem was that the two instructions to be executed at boot prom=
pt 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 comi=
ng
from the passthrough of the network cards by the hypervisor bhyve to the v=
irtual machine.
Best regards
