Please take a look at Intel 64 and IA-32 Architectures Optimization Reference Manual.

A white paper "Unleash IA Virtualization Accelerations in Real-Time Embedded Systems" talks about the cost of VM entry and exit which can give some additional information.

Did you look at Intel System Programming Guide, Volume 3B?
