Abstract

Embodiments relate to systems and methods for storage allocation in the provisioning of virtual machines. A provisioning (or “cobbler”) server can interact with a local virtual machine installation client to initiate software provisioning to a set of virtual machines. The provisioning process can entail, for example, the selection and delivery of an operating system to the target set of virtual machines, as well as the installation of applications or other software. In conjunction with the provisioning process, the virtual machine installation client can identify and access a set of storage resources, such as hard disk or other storage, to be associated with the set of virtual machines, which themselves contain no local storage. That client can determine an allocation of the set of storage resources to each virtual machine in the set of virtual machines, for instance on a pro-rata basis or based on processing consumption or other factors.

Claims

1. A method of allocating storage to virtual machines in a software provisioning environment, comprising:

receiving, from a provisioning server, software to be utilized by a set of virtual machines;

identifying an initial amount of storage resources to be allocated to each virtual machine in the set of virtual machines, wherein the initial amount comprises an equal share of available storage resources in a common storage pool for the set of virtual machines;

automatically allocating, by a processor, the initial amount of the storage resources to each virtual machine in the set of virtual machines from the common storage pool; and

installing the software on the storage resources allocated to the set of virtual machines.

2. The method of claim 1, wherein the common storage pool comprises a set of mass storage servers.

3. The method of claim 2, wherein the set of mass storage servers comprises at least one of a set of hard disks and a set of electronic memory resources.

4. The method of claim 1, wherein at least a portion of the software is stored to the storage resources for respective machines in the set of virtual machines.

5. The method of claim 1, further comprising:

dynamically reallocating the storage resources for the set of virtual machines based on conditions in the set of virtual machines.

6. The method of claim 1, further comprising:

generating a storage allocation table for the set of virtual machines, wherein the storage allocation table comprises an identification of the storage resources allocated to the set of virtual machines.

7. The method of claim 1, wherein the storage resources comprise at least one virtual disk.

8. A system for generating an allocation of storage to virtual machines in a software provisioning environment, comprising:

an interface to a provisioning server; and

a processor configured to execute a remote virtual machine installation client, and configured to communicate with the provisioning server via the interface, the remote virtual machine installation client being configured to—

receive, from the provisioning server, software to be utilized by a set of virtual machines,

identify an initial amount of storage resources to be allocated to each virtual machine in the set of virtual machines, wherein the initial amount comprises an equal share of available storage resources in a common storage pool for the set of virtual machines;

automatically allocate the initial amount of the storage resources to each virtual machine in the set of virtual machines from the common storage pool, and

install the software on the storage resources allocated to the set of virtual machines.

9. The system of claim 8, wherein the common storage pool comprises a set of mass storage servers.

10. The system of claim 9, wherein the set of mass storage servers comprises at least one of a set of hard disks and a set of electronic memory resources.

11. The system of claim 8, wherein at least a portion of the software is stored to the storage resources for respective machines in the set of virtual machines.

12. The system of claim 8, wherein the remote virtual machine installation client is configured to—

dynamically reallocate the storage resources for the set of virtual machines based on conditions in the set of virtual machines.

13. The system of claim 8, wherein the remote virtual machine installation client is configured to—

generate a storage allocation table for the set of virtual machines, wherein the storage allocation table comprises an identification of the storage resources allocated to the set of virtual machines.

14. The system of claim 8, wherein the storage resources comprise at least one virtual disk.

15. A remote virtual machine installation client embodied on a non-transitory computer readable medium and configured to cause a processor to perform the method, comprising:

receiving, from a provisioning server, software to be utilized by a set of virtual machines;

identifying an initial amount of storage resources to be allocated to each virtual machine in the set of virtual machines, wherein the initial amount comprises an equal share of available storage resources in a common storage pool for the set of virtual machines;

automatically allocating the initial amount of the storage resources to each virtual machine in the set of virtual machines from the common storage pool; and

installing the software on the storage resources allocated to the set of virtual machines.

16. The remote virtual machine installation client of claim 15, wherein the common storage pool comprises a set of mass storage servers.

17. The remote virtual machine installation client of claim 16, wherein the set of mass storage servers comprises at least one of a set of hard disks and a set of electronic memory resources.

18. The remote virtual machine installation client of claim 15, wherein at least a portion of the software is stored to the storage resources for respective machines in the set of virtual machines.

19. The remote virtual machine installation client of claim 15, the method further comprising:

dynamically reallocating the storage resources for the set of virtual machines based on conditions in the set of virtual machines.

20. The remote virtual machine installation client of claim 15, the method further comprising:

generating a storage allocation table for the set of virtual machines, wherein the storage allocation table comprises an identification of the storage resources allocated to the set of virtual machines.

21. The remote virtual machine installation client of claim 15, wherein the allocated storage resources comprise at least one virtual disk.
