Well, any steal time clock will be hypervisor specific, but if we agree that anything that enables CONFIG_PARAVIRT_TIME_ACCOUNTING provides a u64 steal_time_clock(int cpu) function then all should be well, right?
The bit you have in kvm is almost that, except it assumes cpu == this_cpu.
You simply cannot rely on the silly tick accounting to drive any clock, its archaic.
