An explicit 0 also clears any limit. A non-zero value for a given total

It is up to the hypervisor to determine how to handle the length values.
For the qemu hypervisor, if an I/O limit value or maximum value is set,
then the default value of 1 second will be displayed. Supplying a 0 will
reset the value back to the default.
