Claim 14:
15. A destination host system comprising:
a destination hypervisor;
a memory; and
a non-transitory computer readable medium having stored thereon program code that, when executed, causes the destination hypervisor to:
at a time of performing a live migration of a virtual machine (VM) from a source host system to the destination host system, receive a live migration payload packet from a source hypervisor running on the source host system, the live migration payload packet including error metadata for a guest memory page of the VM that indicates the guest memory page is at least partially corrupted; and
upon completion of the live migration:
initiate execution of a migrated copy of the VM on the destination host system;
trap a memory access to the guest memory page during the execution of the migrated copy of the VM; and
in response to the trapping, raise a virtual memory exception to a guest operating system (OS) of the migrated copy of the VM, the virtual memory exception informing the guest OS that the guest memory page is at least partially corrupted.
