Abstract

The present disclosure relates to methods and systems for managing a guest virtual machine executing within a virtualized environment. A daemon is established on a guest virtual machine executing within a virtualized environment. The daemon is configured to communicate with a management service virtual machine executing within the virtualized environment. The daemon receives, from the management service virtual machine via an application layer protocol, a request identifying an action type of a plurality of predetermined action types. The daemon identifies the action type of the plurality of predetermined action types from the received request and performs an action corresponding to the identified action type. In some implementations, the application layer protocol is one of Hypertext Transfer Protocol (HTTP) or Hypertext Transfer Protocol Secure (HTTPS).

Claims

1-20. -20. (canceled)

21. A method comprising:

(a) establishing a daemon on a guest virtual machine with a port of the guest virtual machine configured for communications;

(b) receiving, by the daemon via the port via and an application layer protocol using a security certificate, from a management service virtual machine, a request identifying a type of action; and

(c) initiating, by the daemon, the action corresponding to the type of action of the request.

22. The method of claim 21, wherein (a) further comprises deploying a file corresponding to the daemon within the guest virtual machine.

23. The method of claim 21, wherein (a) further comprises generating a security certificate to use for communications between the daemon and the management service virtual machine.

24. The method of claim 21, wherein (a) further comprises configuring the port of the guest virtual machine to communicate with the management service virtual machine.

25. The method of claim 21, wherein (b) further comprises receiving, by the daemon, the request via JavaScript Object Notation (JSON) over the application layer protocol comprising Hypertext Transfer Protocol (HTTP).

26. The method of claim 21, wherein (b) further comprises receiving, by the daemon, the request identifying the type of action to initialize one or more network configurations and wherein (c) further comprises performing, by the daemon, the action corresponding to initializing one or more network configurations.

27. The method of claim 21, wherein (b) further comprises receiving, by the daemon, the request identifying the type of action for providing statistics and wherein (c) further comprises performing, by the daemon, the action corresponding to providing statistics.

28. The method of claim 21, wherein (b) further comprises receiving, by the daemon, the request identifying a script to execute for the type of action and wherein (c) further comprises executing, by the daemon, the script to perform the action corresponding to the type of action.

29. The method of claim 21, wherein (b) further comprises receiving, by the daemon, the request identifying the type of action for upgrading an image and wherein (c) further comprises performing, by the daemon, the action corresponding to upgrading the image.

30. The method of claim 29, further comprising receiving the image with the request and upgrading, by the daemon, the guest virtual machine using the image.

31. A system comprising:

a virtualized environment executing on a hardware device, the virtualized environment configured to establish a guest virtual machine and a management service virtual machine;

a daemon configured to be established on the guest virtual machine with a port of the guest virtual machine configured for communications, to receive via the port via and an application layer protocol using a security certificate, from the management service virtual machine, a request identifying a type of action; and

to initiate the action corresponding to the type of action of the request.

32. The system of claim 31, further comprising a file corresponding to the daemon configured to be deployed via the guest virtual machine.

33. The system of claim 31, further comprising a security certificate generated to use for communications between the daemon and the management service virtual machine.

34. The system of claim 31, wherein the port of the guest virtual machine is configured to communicate with the management service virtual machine.

35. The system of claim 31, wherein content of the request comprises JavaScript Object Notation (JSON) and the application layer protocol comprises Hypertext Transfer Protocol (HTTP).

36. The system of claim 31, wherein by the daemon is further configured to receive the request identifying the type of action to initialize one or more network configurations and perform the action corresponding to initializing one or more network configurations.

37. The system of claim 31, wherein the daemon is further configured to receive the request identifying the type of action for providing statistics and perform the action corresponding to providing statistics.

38. The system of claim 31, wherein the daemon is further configured to receive the request identifying a script to execute for the type of action and execute the script to perform the action corresponding to the type of action.

39. The system of claim 31, wherein the daemon is further configured to receive the request identifying the type of action for upgrading an image and perform the action corresponding to upgrading the image.

40. The system of claim 39, wherein the daemon is further configured to receive the image with the request and upgrade the guest virtual machine using the image.
