Replace hrtimer based timer emulation with host timebase (ktime_t) comparisons on guest entry. This avoids host load when guests are scheduled out, removes a spinlock acquision on entry (i8254.c's inject_lock), and makes future improvements easier.
I wonder if we're really winning with this. Guests should be scheduled-out-but-not-halted rarely, and in all other cases we need to keep the timer. A timer comparison on each guest entry might be expensive (maybe not so much with tsc based timers).
