Abstract
A method for managing multiple nodes hosting multiple memory segments, including: identifying a failure of a first node hosting a first memory segment storing a hypervisor; identifying a second memory segment storing a shadow of the hypervisor and hosted by a second node; intercepting, after the failure, a hypervisor access request (HAR) generated by a core of a third node and comprising a physical memory address comprising multiple node identification (ID) bits identifying the first node; modifying the multiple node ID bits of the physical memory address to identify the second node; and accessing a location in the shadow of the hypervisor specified by the physical address of the HAR after the multiple node ID bits are modified.
