Abstract
A page scanner may be configured to identify, during a live migration of a virtual machine including a transfer of a plurality of memory pages from source hardware resources to destination hardware resources, a candidate memory page of the plurality of memory pages to include in the transfer while at least one operation of the virtual machine continues to execute. A fingerprint comparator may be configured to compare a candidate page fingerprint of the candidate memory page to existing page fingerprints of existing memory pages stored using the second hardware resources, and further configured to determine, based on the comparing, that a duplicate of the candidate page is included within the existing memory pages. A duplicate page handler may be configured to facilitate continued execution of the virtual machine using the duplicate of the candidate page and the second hardware resources.
