One of the problems is that existing binaries set the exclude_guest flag
(https://lkml.org/lkml/2012/7/9/292).

Correction, I meant to say one of the problems is that existing binaries sets the flag to 0 when precise is used.


So, requesting users to update their binaries if they want to use
precise sampling is not acceptable. A 100% catastrophic failure of all
running VMs is acceptable? All VMs will crash and there is no direct
causal relationship.
