I used VirtualBox. I gave a try to bhyve. I am using FreeBSD for all work
I need. I need windows for some tasks: some VPN (I am not able to
connect with vpnc, openconnect, racoon, strongswan), Iphone backup,
etc. I am not able to use a single hypervisor for all of that. Could you
recommend one?
thanks.
