  • Live virtual machine relocation to accommodate reversible relocations in a heterogeneous cluster of hypervisor versions
    Patent number: 11720392
    Abstract: Dynamic relocation of virtual machines among hypervisors in a relocation domain is provided. A hypervisor is initialized in a subdomain of the relocation domain. A record of architecture characteristics is retrieved for each hypervisor in the relocation domain. A new canonical architectural description (ARD) is created for each subdomain in the relocation domain. An effective adapter characteristic representation is created for each virtual machine defined to the hypervisor. The record of architecture characteristics for each hypervisor in the relocation domain is updated.
