Managing the migration of virtual machines in the presence of uncorrectable memory errors

A non-transitory computer readable storage medium having stored thereon program code executable by a destination hypervisor running on a destination host system, the program code embodying a method comprising:

• at a time of performing a live migration of a virtual machine (VM) from a source host system to the destination host system, receiving 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:
• initiating execution of a migrated copy of the VM on the destination host system;
• trapping a memory access to the guest memory page during the execution of the migrated copy of the VM;
• and
• in response to the trapping, raising 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.

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.
