Subject:   what event timer should I use on bhyve vm's and hosts
Message-ID:  <CAGBxaXnRbSvf1zXSOk0MMfvfX0yQopYJLoY=NPiNG4osaFywpQ@mail.gmail.com>

I currently have 3 vm's (all 13.1) on a 13.1 host that is using HPET
event timer and the vm's are also using it.   Specifically all the
/etc/sysconfig.conf's have:

kern.eventtimer.timer=HPET
machdep.idle=mwait

I have a NFS server on one of the VM's and the other VM's are NFS
clients of that server.   Before I turned HPET on on both the host and
the guests NFS rarely if ever froze now it is freezing every few days.

Is the event timer the problem or something else?
