Techniques for migrating virtual machines (VMs) in the presence of uncorrectable memory errors are provided. According to one set of embodiments, a source host hypervisor of a source host system can determine, for each guest memory page of a VM to be migrated from the source host system to a destination host system, whether the guest memory page is impacted by an uncorrectable memory error in a byte-addressable memory of the source host system. If the source host hypervisor determines that the guest memory page is impacted, the source host hypervisor can transmit a data packet to a destination host hypervisor of the destination host system that includes error metadata identifying the guest memory page as being corrupted. Alternatively, if the source host hypervisor determines that the guest memory page is not impacted, the source host hypervisor can attempt to read the guest memory page from the byte-addressable memory in a memory exception-safe manner.
A method comprising, at a time of executing a live migration of a virtual machine (VM) from a source host system to a destination host system:
A non-transitory computer readable storage medium having stored thereon program code executable by source hypervisor of a source host system, the program code embodying a method comprising, at a time of executing a live migration of a virtual machine (VM) from the source host system to a destination host system:
A source host system comprising:
