[libvirt-users] Disk space exhaustion

Hello,

what happens when an instance writes data with 0% available physical 
disk space, on QCOW2 images for instance, apart from destruction and 
unpredictability?
I'm aware that monitoring is mandatory in production environments, but 
are there other known industry tricks to deal with this? Soft/hard limit 
settings, autopause/stop, or does KVM react in doing force shut down the 
VM in question?

Thank you,
Fabrizio.
