Abstract

A method for moving a hypervisor in a data grid. The method can include, receiving, from a system administrator, a request to move a host from a first cluster to a second cluster in a data grid, wherein a hypervisor is registered at the host to manage the host. The method can further include identifying, by the virtualization manager, a first configuration of the first cluster. The method can further include identifying, by the virtualization manager, a second configuration of the second cluster. The method can further include determining, by the virtualization manager, differences between the first configuration and the second configuration. The method can further include identifying current configuration attributes of the hypervisor associated with the first cluster. The method can further include adjusting, by the virtualization manager, configuration attributes of the hypervisor that differ for the configuration of the second cluster.

First claim

What is claimed is:

1. A computer-readable non-transitory storage medium comprising executable instructions that, when executed by a processing device executing a virtual machine manager, cause the processing device to perform operations, comprising:
receiving a request to move a host from a first cluster to a second cluster in a data grid;
identifying, by the virtualization manager, a first configuration of the first cluster;
identifying, by the virtualization manager, a second configuration of the second cluster;
identifying, by the virtualization manager, differences between the first configuration and the second configuration;
removing, by the virtualization manager, the host from the first cluster;
adjusting, in view of the identified differences, configuration attributes of a hypervisor being executed by the host, wherein the configuration attributes comprise at least one of drivers or settings of the hypervisor; and
activating, by the virtualization manager, the host at the second cluster with the adjusted configuration attributes of the hypervisor.

2. The computer-readable non-transitory storage medium of claim 1 , wherein the configuration attributes are provided by at least one of: network configuration parameters, storage configuration parameters, memory configuration parameters, or processor configuration parameters.

3. The computer-readable non-transitory storage medium of claim 1 , wherein the operations further comprise maintaining, by the virtualization manager, a database of configuration attributes associated with a plurality of clusters in the data grid.

4. The computer-readable non-transitory storage medium of claim 3 , wherein the first configuration and the second configuration are identified using the database.

5. The computer-readable non-transitory storage medium of claim 1 , wherein the operations further comprise maintaining, by the virtualization manager, the configuration attributes of the hypervisor that are the same for the first cluster and the second cluster.

6. The computer-readable non-transitory storage medium of claim 1 , wherein the first cluster is at a first data center and the second cluster is at a second data center in the data grid.

7. A method, comprising:
receiving a request to move a host from a first cluster to a second cluster in a data grid;
identifying, by a virtualization manager, a first configuration of the first cluster;
identifying, by the virtualization manager, a second configuration of the second cluster;
identifying, by the virtualization manager, differences between the first configuration and the second configuration;
removing, by the virtualization manager, the host from the first cluster;
adjusting, in view of the identified differences, configuration attributes of a hypervisor being executed by the host, wherein the configuration attributes comprise at least one of drivers or settings of the hypervisor; and
activating, by the virtualization manager, the host at the second cluster with the adjusted configuration attributes of the hypervisor.

8. The method of claim 7 , wherein the configuration attributes comprise values of at least one of parameters of the hypervisor.

9. The method of claim 7 , further comprising maintaining, by the virtualization manager, a database of configuration attributes associated with a plurality of clusters in the data grid.

10. The method of claim 9 , wherein the first configuration and the second configuration are identified using the database.

11. The method of claim 7 , further comprising, maintaining, by the virtualization manager, the configuration attributes of the hypervisor that are the same for the first cluster and the second cluster.

12. The method of claim 7 , wherein the first cluster is at a first data center and the second cluster is at a second data center in the data grid.

13. A system comprising:
a memory; and
a processing device, coupled to the memory, the processing device to:
receive, from a system administrator, a request to move a host from a first cluster to a second cluster in a data grid, wherein a hypervisor is registered at the host to manage the host;
identify, by a virtualization manager, a first configuration of the first cluster;
identify, by the virtualization manager, a second configuration of the second cluster;
determine, by the virtualization manager, differences between the first configuration and the second configuration;
identify current configuration attributes of the hypervisor associated with the first cluster;
removing, by the virtualization manager, the host from the first cluster;
adjust, by the virtualization manager, configuration attributes of the hypervisor that differ for the configuration of the second cluster, wherein the configuration attributes comprise at least one of drivers or settings of the hypervisor; and
activating, by the virtualization manager, the host at the second cluster with the adjusted configuration attributes of the hypervisor.

14. The system of claim 13 , the processing device further to: maintain, by the virtualization manager, a database of configuration attributes associated with a plurality of clusters in the data grid.

15. The system of claim 14 , wherein the first configuration and the second configuration are identified using the database.
