Abstract

In one embodiment, a system for managing communication connections in a virtualization environment includes (1) a first host machine implementing a virtualization environment based on a first platform, wherein the first host machine includes a first hypervisor, at least one virtual machine, and one or more virtual infrastructure elements and (2) a virtual disk including a plurality of storage devices. A management module for the system may perform steps to convert the first host machine to a second platform by installing (on the first host machine) a second hypervisor associated with the second platform, disabling the first hypervisor, capturing a configuration describing elements of a virtual infrastructure associated with the first hypervisor, registering the captured configuration with the second hypervisor, creating elements of the captured configuration in the context of the second platform and in association with the second hypervisor, and then enabling the second hypervisor.

Dependent claims

A system for managing communication connections in a virtualization environment, comprising:

a first host machine implementing a virtualization environment based on a first platform, wherein the first host machine comprises a first hypervisor, at least one virtual machine (VM), and one or more virtual infrastructure elements;
one or more second host machines implementing a virtualization environment based on a second platform, wherein each of the second host machines comprises a hypervisor, at least one user virtual machine (UVM), one or more virtual infrastructure elements, and one or more I/O controllers;
and
a virtual disk comprising a plurality of storage devices, the virtual disk being accessible by the I/O controllers, wherein the I/O controllers conduct I/O transactions with the virtual disk based on I/O requests received from the UVMs;
wherein a management module for the system performs steps to convert the first host machine to the second platform by:
installing, on the first host machine, a second hypervisor associated with the second platform;
capturing a configuration describing elements of a virtual infrastructure associated with the first hypervisor, wherein the captured configuration is stored in the virtual disk;
registering the captured configuration with the second hypervisor;
creating elements of the captured configuration in the context of the second platform and in association with the second hypervisor;
and
enabling the second hypervisor.

8 more elements

A method for converting a host machine implementing a virtualization environment from one platform to another platform, comprising, by a management module:

installing, on a first host machine implementing a virtualization environment based on a first platform operating with a first hypervisor, at least one VM, and one or more virtual infrastructure elements, a second hypervisor associated with a second platform, the second platform being associated with a virtualization environment implemented on one or more second host machines, wherein each of the second host machines comprises a hypervisor, at least one UVM, one or more virtual infrastructure elements, and one or more I/O controllers;
capturing a configuration describing elements of a virtual infrastructure associated with the first hypervisor, wherein the captured configuration is stored in a virtual disk comprising a plurality of storage devices, the virtual disk being accessible by the I/O controllers, wherein the I/O controllers conduct I/O transactions with the virtual disk based on I/O requests received from the UVMs;
registering the captured configuration with the second hypervisor;
creating elements of the captured configuration in the context of the second platform and in association with the second hypervisor;
and
enabling the second hypervisor.
