Regardless of filesystem type, determining the cause of the corruption
should be attempted and corrected first if possible. Could multiple
VMs somehow be writing to the same data in the main FS simultaneously
per chance? (just a thought, as this is often a cause of corruption
in non-clustered filesystems, but I do not fully understand your config)

Also, running the VMs as disk files in a filesystem should really be
avoided if at all possible. In my experience, it's better to use logical
volumes directly for VM images for performance, scalability, and
generally less layers of stuff to fail in the IO path.

And of course, a simple nightly rsync of stuff that matters should be
setup... but you know that quite well now :(

I've had very good experiences with this:

It's simple, and versions the backups with excellent space, time and
bandwidth utilization so you can roll back to configurable points in
time easily, without consuming a bunch of space unnecessarily.
