 Description   

The "-gt" option in the shell "['" (aka "test") command compares integers.

ladvise_willread_performance() in sanity.sh uses "scale=2" to ask bc to calculate values to 2 decimal places.  These values are then compared with "-gt" which will fail (unless by luck they are integers).

This failure is not normally noticed as the error is only reported when no vm is detected.  (When I run qemu, no vm is detected, so I notice.)
