Re: bhyve guests: what clock source to use?

[Sean McBride]

Thanks for your reply Paul.

I guess what I'm ignorant of is: are the time sources available for the guest 
OS to choose from the same as the host's?  i.e. are they basically passed 
through?  Or are they emulated or altered by bhyve?

Cheers,

Sean
