The bhyve guest supports running the same software that can be run on the host CPU (32 and 64 bit) The CPU and RAM used by a bhyve buest is shared with the host, so yes you could start 4 instances with 4G available to each, but as each uses more memory at the same time the system will start swapping and slowing down. Maybe run three with 4G and one with 3G You could also look at creating 32 bit jails as they have less overhead due to each sharing the kernel with the host system. 21.7 of the handbook explains setting up bhyve guests. https://www.freebsd.org/doc/en/books/handbook/virtualization-host-bhyve.html Have a look at sysutils/vm-bhyve it makes using bhyve a lot simpler. https://github.com/churchers/vm-bhyve The freebsd-virtualization mailing list would be a better place to ask for more specific help. -- FreeBSD - the place to B...Software Developing Shane Ambler
