Abstract
The present disclosure provides techniques for reimaging physical hosts from a first hypervisor to a second hypervisor. A method includes designating one of a plurality of physical hosts as a coordinating host, receiving a service request to reimage target hosts, obtaining installation media for the second hypervisor, and installing the second hypervisor on each target host. The installation is performed by streaming the installation media from the coordinating host to each of the target hosts. The method enables efficient transition between different hypervisors across multiple physical hosts in a coordinated manner.
Claims20
A computer-implemented method comprising:
- designating one of a plurality of physical hosts as a coordinating host, wherein each of the physical hosts comprises a baseboard management controller and a first hypervisor;
- receiving, by the coordinating host, a service request to reimage target hosts of the physical hosts from the first hypervisor to a second hypervisor, the second hypervisor being different than the first hypervisor;
- obtaining, by the coordinating host, an installation media for the second hypervisor in response to the service request;
- and
- installing the second hypervisor on each of the target hosts by streaming the installation media from the coordinating host to the baseboard management controller of each of the target hosts.
A computer system comprising:
- a plurality of physical hosts, each physical host comprising a baseboard management controller and a first hypervisor, wherein a coordinating host designated from the physical hosts is configured to:
- receive a service request to reimage target hosts of the physical hosts from the first hypervisor to a second hypervisor, the second hypervisor being different than the first hypervisor;
- obtain an installation media for the second hypervisor in response to the service request;
- and
- install the second hypervisor on each of the target hosts by streaming the installation media from the coordinating host to the baseboard management controller of each of the target hosts.
A computer device comprising:
- a processor;
- and
- a non-transitory computer-readable medium storing instructions which, when executed by the processor, cause the processor to:
- designate one of a plurality of physical hosts as a coordinating host, wherein each of the physical hosts comprises a baseboard management controller and a first hypervisor;
- receive a service request to reimage target hosts of the physical hosts from the first hypervisor to a second hypervisor, the second hypervisor being different than the first hypervisor;
- obtain an installation media for the second hypervisor in response to the service request;
- and
- install the second hypervisor on each of the target hosts by streaming the installation media from the coordinating host to the baseboard management controller of each of the target hosts.
