Multiple Ethereum full nodes sharing the same database?

Hey guys, I'm trying to setup multiple ETH full nodes within my network (via different machines and VM's) for various testing purposes, but would prefer not to sync databases a bunch of times if possible.

Is it possible to link multiple VM and/or network PC instances of the full Ethereum nodes and have them share the same database? Lite nodes will not work for what I need.

Thanks for your help!
