Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 17:
18. A computing device comprising:
a random access memory (RAM) comprising a plurality of memory pages;
a processor device coupled to the RAM; and
a first hypervisor module that interfaces with the processor device and is to iteratively:
determine that content of a memory page of the plurality of memory pages has been modified;
send the content of the memory page to a second hypervisor module on a second computing device;
identify, for corruption-detection purposes, at least one other memory page of the plurality of memory pages that was previously sent to the second computing device, the at least one other memory page being identified without receipt of a request from the second computing device;
generate a first verification value based on content of the at least one other memory page; and
send the first verification value and a memory page identifier that identifies the at least one other memory page to the second hypervisor module on the second computing device without sending the content of the at least one other memory page, so that the second computing device can calculate a second verification value for the at least one other memory page that was previously sent to the second computing device and determine whether the at least one other memory page that was previously sent to the second computing device has become corrupted by comparing the first verification value and the second verification value.
