As long as your CPU has the needed features (it should) you shouldn't
have any problems. 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.
Have a look at sysutils/vm-bhyve it makes using bhyve a lot simpler.
The freebsd-virtualization mailing list would be a better place to ask
for more specific help.
