Similarly to live migration, starting a VM from some serialized state (aka snapshot) is an event which calls for adjusting guest clocks, hence a hypervisor should increase the disruption_marker before resuming the VM vCPUs, letting the guest know. However, loading a snapshot, is slightly different than live migration, especially since we can start multiple VMs from the same serialized state. Apart from adjusting clocks, the guest needs to take additional action during such events, e.g. recreate UUIDs, reset network adapters/connections, reseed entropy pools, etc. These actions are not necessary during live migration. This calls for a differentiation between the two triggering events. [...]
