I have serveral Ubuntu server running in virtual machines on my host.
Everything works fine but there is a problem. I use NFS to share a
common directory between the VMs. And as the machines user IDs are
different so even when user and password are the same, they cannot
write data or use data thats from another VM. Changing user IDs did
not work properly, I rolled that back.

So, someone mentioned Kerberos to manage users. This seems a bit too
much effort. Is there a better, lightweight solution? Or even another
way to share a common disk space? How is this done usually?

I have an SMB share that is shared among all my VMs. They connect
using the same credentials so it was easy to manage.

Same, I find that Samba works really well for this purpose.
