            Bug ID: 249981
           Summary: bhyve man page cpu pinning description could be more
                    helpful
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bhyve
          Assignee: virtualization at FreeBSD.org
          Reporter: grehan at FreeBSD.org

bz has some feedback that the '-p' option could have some additional text, and
perhaps an example.

The text could say that the guest vCPUs are numbered from 0, as are host CPUs,
and that a '-p' option is required for each guest vCPU that needs to be pinned.

For example, mapping a 4 vCPU guest to host CPUs 12-15 would require

  -p 0:12 -p 1:13 -p 2:14 -p 3:15
