overcommiting CPU's in bhyve, I have a 2 core, 4 thread system with
6 VM's, each vm using 1 vCPU, this is a 50% overcommit and it my

No I have not. As far as you stick with 1 vCPU per virtual host, you
should

It is all a mater of Load, as long as your host load stays
below the number of CPU threads you actually have things
in this aspect tend to work just fine. And if you do exceed
this everyone slows down in a fairly fair fashion.

So if one guest launch a lot of cpu hungry thread it could "starve"
the others guests with less thread usgin cpu time.
As far as what I heard here on this forum, you should NOT overcommit the
vCPUs.
When you keep the number of vCPUs assigned to your vms lower than
physical CPUs (= hypert
In Xen there is a maxvcpus which limit the number of CPUs but they could baloon
down if not busy so that other clients who are busy can use the CPUs. In bhyve
(at least in vm-bhyve) there is only a cpus line in the config. >Is this a

Greetings. I have just recently started using bhyve (previously a Xen
user). I am using vm-bhyve to manage it. I have a few questions.
First question, am I making the right choice by switching and, if so, is
bhyve the right choice to switch to? I realize that that is an
impossible question but
