System and method for VM cloning in a software defined storage environment
An illustrative embodiment disclosed herein is a method including receiving, by a controller virtual machine (CVM) and from a hypervisor, a request to clone a virtual machine (VM) state. The VM state includes a parent state and a snapshot. The method further includes cloning, by the CVM, the parent state and the snapshot to generate a cloned parent state and a cloned snapshot, respectively, and sending, by the CVM and to the hypervisor, data indicating successful cloning of the parent state and the snapshot.
1. A computer-implemented method comprising:
receiving, by a controller virtual machine (CVM) and from a hypervisor, a request to clone a virtual machine (VM) state, wherein the VM state includes a parent state and a snapshot;
cloning, by the CVM, the parent state and the snapshot to generate a cloned parent state file and a cloned snapshot file, respectively; and
sending, by the CVM and to the hypervisor, data indicating successful cloning of the parent state and the snapshot;
wherein the hypervisor modifies a universally unique identifier of a configuration file for each of the cloned parent state file and the cloned snapshot file.
2. The method of claim 1 , wherein the parent state includes an indication of a relationship to the snapshot.
3. The method of claim 1 , further comprising:
detecting, by the CVM, a second snapshot; and
cloning, by the CVM, the second snapshot.
4. The method of claim 1 , wherein each of the parent state and the snapshot include a configuration file and a data file.
5. The method of claim 1 , wherein the hypervisor removes a first indication of a relationship between the snapshot and the cloned snapshot, and wherein the hypervisor generates a second indication of a relationship between the cloned parent state file and the cloned snapshot file.
6. The method of claim 1 , wherein the hypervisor registers a cloned VM including the cloned parent state file and the cloned snapshot file.
7. An apparatus comprising a processor having programmed instructions to:
receive a request to clone a virtual machine (VM) state, wherein the VM state includes a parent state and a snapshot;
clone the parent state and the snapshot to generate a cloned parent state file and a cloned snapshot file, respectively; and
send data indicating successful cloning of the parent state and the snapshot,
wherein the hypervisor modifies a universally unique identifier of a configuration file for a configuration file for a configuration file for each of the cloned parent state file and the cloned snapshot file.
8. The apparatus of claim 7 , wherein the parent state includes an indication of a relationship to the snapshot.
9. The apparatus of claim 7 , the processor having further programmed instructions to:
detect a second snapshot; and
clone the second snapshot.
10. The apparatus of claim 7 , wherein each of the parent state and the snapshot include a configuration file and a data file.
11. The apparatus of claim 7 , wherein the hypervisor removes a first indication of a relationship between the snapshot and the cloned snapshot, and wherein the hypervisor generates a second indication of a relationship between the cloned parent state file and the cloned snapshot file.
12. The apparatus of claim 7 , wherein the hypervisor registers a cloned VM including cloned parent state file and the cloned snapshot file.
13. A non-transitory computer readable storage medium to store a computer program configured to execute a method comprising:
receiving a request to clone a virtual machine (VM) state, wherein the VM state includes a parent state and a snapshot;
cloning the parent state and the snapshot to generate a cloned parent state file and a cloned snapshot file, respectively; and
sending data indicating successful cloning of the parent state and the snapshot,
wherein the hypervisor modifies a universally unique identifier of a configuration file for a configuration file for a configuration file for each of the cloned parent state file and the cloned snapshot file.
14. The non-transitory computer readable medium of claim 13 , wherein the parent state includes an indication of a relationship to the snapshot.
15. The non-transitory computer readable medium of claim 13 , the method further comprising:
detecting, by the CVM, a second snapshot; and
cloning, by the CVM, the second snapshot.
16. The non-transitory computer readable medium of claim 13 , wherein each of the parent state and the snapshot include a configuration file and a data file.
17. The non-transitory computer readable medium of claim 13 , wherein the hypervisor removes a first indication of a relationship between the snapshot and the cloned snapshot, and wherein the hypervisor generates a second indication of a relationship between the cloned parent state file and the cloned snapshot file.
18. The non-transitory computer readable medium of claim 13 , wherein the hypervisor registers a cloned VM including the cloned parent state file and the cloned snapshot file.
19. The method of claim 1 , wherein the cloned parent state file and the cloned snapshot file are separate files.
20. The non-transitory computer readable medium of claim 13 , wherein the cloned parent state file and the cloned snapshot file are separate files.
