no... we don't because we don't want to create a performance issue.

the vm is writing until it runs out of space. if we can extend the lv we 
do (vdsm will run lvextend).
However, the user should never see this error at all even if we are 
running on a thin provision disk since this is a low level operation 
which takes very little time.
If we can see the vm's pausing than it's either a UI refresh issue, 
internal communication issue between the host and storage or an actual bug.

Adding Eduardo and Federico.
