  At low redshift, there are fundamental correlations between the mass of
supermassive black holes (MBH) and the mass (Mbulge) and luminosity of the host
galaxy bulge. We investigate the same relation at z>=1. Using virial mass
estimates for 11 quasars at z >~2 to measure their black hole mass, we find
that black holes at high z fall nearly on the same MBH versus R-band magnitude
(MR) relation (to ~0.3 mag) as low-redshift active and inactive galaxies,
without making any correction for luminosity evolution. Using a set of
conservative assumptions about the host galaxy stellar population, we show that
at z>~2 (10 Gyrs ago) the ratio of MBH/Mbulge was 3--6 times larger than today.
Barring unknown systematic errors on the measurement of MBH, we also rule out
scenarios in which moderately luminous quasar hosts at z>~2 were fully formed
bulges that passively fade to the present epoch. On the other hand, 5 quasar
hosts at z~1 are consistent with current day MBH-MR relationship after taking
into account evolution, appropriate for that of E/S0 galaxies. Therefore, z~1
host galaxies appear to fit the hypothesis they are fully formed early-type
galaxies. We also find that most quasar hosts with absolute magnitudes brighter
than MR = -23 cannot fade below L* galaxies today, regardless of their stellar
population makeup, because their black hole masses are too high and they must
arrive at the local MBH-MR relationship by z=0.
