Hi, all, we are just starting a project that will run a couple of Ubuntu guests on top of bhyve instead of ESXi that we used in the past. As far as I could find out, more or less all bhyve manager/wrapper tools use zvols as the backing store for "raw" guest disk images. I looked at * chyves * iohyve * vm-bhyve So far so good. Yet, this blog article has some very valid (IMHO) points against using them: http://jrs-s.net/2016/06/16/psa-snapshots-are-better-than-zvols Another thing I'm pondering is: wouldn't it be better to run on UFS so you can dedicate as much memory as possible to VMs? So I'm a bit puzzled now on what to do. Any opinions, experiences, war stories to share?
