Hypervisor adjustment for host transfer between clusters

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.

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.
