that there are folks that run hundreds of VMs out of 

So it's probably more about the data usage than just a 
generic viability statement as you made in your post.

Gluster does not support databases, though many people
use them on gluster without much problem. 

Please let me know if you see some problem with unstructured 
file data on VMs. I would be happy to help debug that problem.

Subject: [Gluster-users] Self heal with VM Storage

I am running gluster as a storage backend for VM storage (KVM guests). If
one of the bricks is taken offline (even for an instant), on bringing it
back up it runs the metadata check. This causes the guest to both stop
responding until the check finishes and also to ruin data that was in
process (sql data for instance). I'm guessing the file is being locked while
checked. Is there any way to fix for this? Without being able to fix for
this, I'm not certain how viable gluster will be, or can be for VM storage.
