[PATCH v2] kvm: i386: allow TSC to differ by NTP correction bounds without TSC scaling

2020-06-16 Thread Marcelo Tosatti
The Linux TSC calibration procedure is subject to small variations (its common to see +-1 kHz difference between reboots on a given CPU, for example). So migrating a guest between two hosts with identical processor can fail, in case of a small variation in calibrated TSC between them. Allow
