When a vcpu is migrated to another cpu, an unexpected difference in current and previous cpu TSC values can cause a guest to wait indefinitely. A known workaround has been to run kvm with taskset, locking it to a single cpu. This patch series modifies the guest TSC offset as needed to guarantee that the guest sees a monotonically increasing TSC, adds a statistic for vcpu_migrated and updates kvm_stat so the first column isn't truncated.
