Hi Rudy,

This is a valid error message from bhyve, and happens when the file
attached to a block device can't be opened.

This is probably the delay due to core being dumped.

Try running in the foreground (-l com1,stdio) to see if bhyve can
access the iso and zvol OK.
(There is a bug here in that bhyve should just exit out if the backing
image doesn't exist rather than dumping core.)
later,
Peter.
