As Alan already wrote - you can use ZFS inside of the guest but I would 
never choose ZFS in zvol backed guest. I prefere UFS. It is faster and 
does not need so much memory as ZFS does. My VirtualBox and Bhyve guests 
are small. Sometimes <1GB of RAM. Sometimes 2GB of RAM and that is very 
small for ZFS.

May be you can try to limit ZFS ARC size in /etc/sysctl.conf or in 
/boot/loader.conf
vfs.zfs.arc_max
Choose about 1/4 of your guest's RAM size and test it again.

Kind regards
