I have never tried but some people like the vMotion option from VMware and for having tried it, it's quite impressive in action. For the rest, I used jails a long long time ago, I guess Marketing was not behind jails the same way it has been behind VMware products although, to be fair, GSX and ESX have be out there for ages...there has been a lot more press since ESXi4.something and 5 Boris On Wed, Apr 23, 2014 at 4:09 PM, Alejandro Imass wrote: > > On 14-04-22 3:47 PM, edflecko . wrote: > > > > I'm really interested in the comparison of using a FBSD jail rather than > > VMWare in the context of virtualization. > > > > At my business, we heavily use VMWare - you might say we consider > ourselves > > a VMWare "shop". 99% of our servers are virtualized. > > > > I've heard that it's possible to run hundreds, if not thousands, of > > services in FBSD jails on a given host server because of the sharing of > > resources that all of your jails take advantage of.
