Abstract

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.

Claims

1. A computer-implemented method comprising:

identifying, by a migration tool, 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;

migrating, by the migration tool, the operating system to the target virtual machine host computer system; and

causing, by the migration tool, at least one configuration parameter of the operating system to be adjusted based on the first hypervisor.

2. The computer-implemented method of claim 1, wherein causing the at least one configuration parameter to be adjusted comprises:

displaying a user interface facilitating user input as to whether the at least one configuration parameter is to be changed;

receiving user input requesting that the at least one configuration parameter be changed; and

setting the configuration parameter to a value corresponding to the first hypervisor.

3. The computer-implemented method of claim 2, wherein the value is provided by a user or is obtained without user interaction.

4. The computer-implemented method of claim 1, wherein causing the at least one configuration parameter to be adjusted comprises updating, by the migration tool, a configuration file using a value for the at least one configuration parameter based on the first hypervisor or a value acceptable for multiple hypervisors.

5. The computer-implemented method of claim 1, wherein causing the at least one configuration parameter to be adjusted comprises enabling, by the migration tool, a service configured to set the at least one configuration parameter to a value based on the first hypervisor.

6. The computer-implemented method of claim 1, wherein causing the at least one configuration parameter to be adjusted comprises setting, by the migration tool, the at least one configuration parameter to a value based on the first hypervisor.

7. The computer-implemented method of claim 1, wherein:

the operating system was installed on physical hardware of the source computer system; and

migrating the operating system to the target host computer system comprises creating a virtual machine on the target virtual machine host computer system, creating an image of the source computer system, and adding the image to the virtual machine.

8. The computer-implemented method of claim 1, wherein:

the operating system was running on the source computer system in a virtual machine under a second hypervisor, the second hypervisor being of a different type than the first hypervisor; and

migrating the operating system to the target virtual machine host computer system comprises transferring the virtual machine from the source computer system to the target virtual machine host computer system.

9. The computer-implemented method of claim 1, further comprising:

identifying a type of the first hypervisor by performing at least one of;

requesting type information from the first hypervisor, obtaining type information from a configuration store maintained by the first hypervisor, receiving type information from a user, and obtaining type information from a configuration store maintained by the target virtual machine host computer system.

10. The computer-implemented method of claim 1, wherein identifying the first hypervisor running on the target virtual machine host computer system comprises:

receiving a message from the first hypervisor.

11. An apparatus comprising:

a processing device configured to;

identify an operating system to be migrated to a target virtual machine host computer system from a source computer system;

identify a first hypervisor running on the target virtual machine host computer system;

migrate the operating system to the target virtual machine host computer system; and

cause at least one configuration parameter of the operating system to be adjusted based on the first hypervisor.

12. The apparatus of claim 11, wherein causing the at least one configuration parameter to be adjusted comprises:

displaying a user interface facilitating user input as to whether the at least one configuration parameter is to be changed;

receiving user input requesting that the at least one configuration parameter be changed; and

setting the configuration parameter to a value corresponding to the first hypervisor.

13. The apparatus of claim 11, wherein causing the at least one configuration parameter to be adjusted comprises one or more of:

updating, by the migration tool, a configuration file using a value for the at least one configuration parameter based on the first hypervisor or a value acceptable for multiple hypervisors;

enabling, by the migration tool, a service configured to set the at least one configuration parameter to a value based on the first hypervisor; and

setting, by the migration tool, the at least one configuration parameter to a value based on the first hypervisor.

14. The apparatus of claim 11, wherein:

the operating system was installed on physical hardware of the source computer system; and

migrating the operating system to the target host computer system comprises creating a virtual machine on the target virtual machine host computer system, creating an image of the source computer system, and adding the image to the virtual machine.

15. The apparatus of claim 11, wherein:

the operating system was running on the source computer system in a virtual machine under a second hypervisor, the second hypervisor being of a different type than the first hypervisor; and
