Yes, it would be nice if newer viridian-aware kernels did not zero-scrub memory 
at start of day. This was certainly not what we observed with original windows 
7 kernels, which relied on the zero-scrubbing having been done where older 
kernels did not (particularly when setting up pagetables IIRC). That pre-dates 
ballooning in hyper-V of course so I guess it'd be worth examining the 
behaviour of an SP1 system at start of day.
