Adjustment during migration to a different virtualization environment

摘要

An installer installing an operating system on a host computer system detects that the operating system is to be run under a hypervisor, and causes at least one configuration parameter of the operating system to be adjusted based on the hypervisor. A migration tool migrating a virtual machine from one hypervisor to another hypervisor, identifies the types of the two hypervisors, the operating system used by the virtual machine, and causes at least one configuration parameter of the operating system to be adjusted based on the target hypervisor.

主权项

1. A method comprising:
identifying, by a migration tool executed by a processor, an operating system to be migrated to a target virtual machine host computer system from a source computer system; identifying, by the migration tool, a first hypervisor running on the target virtual machine host computer system, wherein the operating system was running under a second hypervisor prior to migration, wherein the first hypervisor comprises a first type and the second hypervisor comprises a second type; migrating, by the migration tool, the operating system to the target virtual machine host computer system; in response to determining the first type of the first hypervisor and determining the second type of the second hypervisor, causing, by the migration tool, a first set of configuration parameters of the operating system to be optimized by the migration tool, wherein the first set of configuration parameters are identified in view of a difference between the first type of the first hypervisor and the second type of the second hypervisor and wherein the identified first set of configuration parameters are adjusted in response to selecting two or more options from the migration tool, wherein the two or more options comprise:
a recommended option to adjust the first set of configuration parameters to default values; anda customizable option to adjust one or more configuration parameters of the first set of configuration parameters to one or more values from a list of selectable configuration parameters comprising a default value, a recommended value, and one or more additional values; in response to failing to determine the first type of the first hypervisor, causing, by the migration tool, a second set of configuration parameters of the operating system to be optimized, wherein the second set of configuration parameters are identified regardless of the first type of the first hypervisor; and in response to determining the first type of the first hypervisor and failing to determine the second type of the second hypervisor, causing, by the migration tool, a third set of configuration parameters of the operating system to be optimized, wherein the third set of configuration parameters are identified independent of the second type of the second hypervisor, wherein the third set of configuration parameters are identified in view of the first type of the first hypervisor.
