206 :Parameters: 64-bit unsigned TSC offset
216 Specifies the guest's TSC offset relative to the host's TSC. The guest's
217 TSC is then derived by the following equation:
221 This attribute is useful to adjust the guest's TSC on live migration,
222 so that the TSC counts the time during which the VM was paused. The
227 1. Invoke the KVM_GET_CLOCK ioctl to record the host TSC (tsc_src),

235    guest's TSC (freq).
251 5. Invoke the KVM_GET_CLOCK ioctl to record the host TSC (tsc_dest) and
254 6. Adjust the guest TSC offsets for every vCPU to account for (1) time
