摘要
Responsive to a hypervisor determining that insufficient local resources are available for reservation to meet a performance parameter for at least one resource specified in a reservation request for a particular logical partition managed by the hypervisor in a host system, the hypervisor identifies another logical partition managed by the hypervisor in the host system that is assigned at the least one resource meeting the performance parameter specified in the reservation request. The hypervisor estimates a first cost of migrating the particular logical partition and a second cost of migrating the another logical partition to at least one other host system communicatively connected in a peer-to-peer network based on at least one previously recorded cost stored by the host system of migrating a previous logical partition to the at least one other host system.
