Abstract

Various systems and processes may be used for virtual disk importation. In particular implementations, systems and processes for virtual disk importation may include the ability to receive a request from a customer of a service provider network to import a virtual disk, which is accessible over a communication network, into the service provider network. The systems and processes may also include the ability to download a portion of a virtual disk file corresponding to the virtual disk, determine the type of the virtual disk by analyzing the downloaded portion, and determine the size of the virtual disk by analyzing the downloaded portion. The systems and processes may further include the ability to determine whether the virtual disk is supported by the service provider network based on the determined type of the virtual disk and download the virtual disk if the virtual disk is supported by the service provider network.

Claims

1. A non-transitory computer-readable storage medium comprising computer-executable instructions stored thereupon that, as a result of being executed by a computer system, cause the computer system to:

receive a request from a customer of a service provider network, which includes a number of server computers hosting virtual machines, to import a virtual disk into the service provider network, the virtual disk being accessible by the service provider network through a wide-area communication network that is external to the service provider network;

download a header of a virtual disk file corresponding to the virtual disk through the communication network;

determine a type of the virtual disk by analyzing the downloaded header for characteristics that correspond to predetermined signatures for virtual disks and as a result of the characteristics failing to match the predetermined signatures, download a different portion of the virtual disk for analysis of the type of the virtual disk;

download a footer of the virtual disk file through the communication network;

perform an integrity check on the virtual disk by comparing at least a portion of the header with at least a portion of the footer;

determine whether the virtual disk is supported by the service provider network based on the type of the virtual disk; and

download the virtual disk through the communication network based at least in part on the virtual disk passing the integrity check and being supported by the service provider network.

2. The computer readable storage medium of claim 1, comprising further computer-executable instructions stored thereupon which, as a result of being executed by a computer system, cause the computer system to:

convert the virtual disk to a format for the service provider network;

determine whether the virtual disk is bootable;

boot the virtual disk if the virtual disk is bootable;

determine that the virtual disk is functioning properly; and

transfer the virtual disk to the customer if the virtual disk is functioning properly.

3. The computer readable storage medium of claim 1, comprising further computer-executable instructions stored thereupon which, as a result of being executed by a computer system, cause the computer system to:

determine that the virtual disk file has a number of virtual disks therein based on the downloaded header;

download a portion of each virtual disk, the portion of each virtual disk being smaller than each of the respective virtual disks;

determine virtual disk types by analyzing the downloaded portion of each virtual disk for characteristics that correspond to predetermined signatures for virtual disks;

determine whether the virtual disks are supported by the service provider network based on the virtual disk types; and

download the virtual disks through the communication network if the virtual disks are supported by the service provider network.

20. The non-transitory computer-readable storage medium of claim 1, wherein the virtual disk is part of a plurality virtual disks stored in an Open Virtualization Format (OVF) package.

21. The non-transitory computer-readable storage medium of claim 20, comprising further computer-executable instructions stored thereupon which, as a result of being executed by a computer system, further cause the computer system to download the entire OVF package if the virtual disk passes the integrity check and is supported by the service provider network.

22. The non-transitory computer-readable storage medium of claim 1, wherein the type of the virtual disk is determined by analyzing the downloaded header for characteristics that correspond to a magic number that matches a portion of a signature for the virtual disk.

4. A method, comprising:

determining whether there is a virtual disk to be imported into a service provider network, the virtual disk being accessible by the service provider network through a communication network that is external to the service provider network;

downloading a header of a virtual disk file corresponding to the virtual disk through the communication network;

determining a type of the virtual disk by analyzing the downloaded header by at least comparing the header of the virtual disk file with a virtual disk signature and in response to the header of the virtual disk file and the virtual disk signature failing to match, downloading an additional portion of the virtual disk file for analysis of the type of the virtual disk;

performing an integrity check on the virtual disk by comparing a portion of a footer of the virtual disk, that has been downloaded, with a portion of the header;

determining whether the virtual disk is supported by the service provider network based on the determined type of the virtual disk; and

downloading the virtual disk through the communication network based at least in part on the virtual disk passing the integrity check and being supported by the service provider network.

5. The method of claim 4, further comprising generating a notification for a customer of the service provider network if the virtual disk is not supported by the service provider network.

6. The method of claim 4, further comprising determining a format of the virtual disk by analyzing the downloaded header, wherein determining whether the virtual disk is supported by the service provider network is also based on the format of the virtual disk.

7. The method of claim 4, further comprising generating a notification for a customer of the service provider network if the virtual disk does not pass the integrity check.

8. The method of claim 4, further comprising:

determining that the downloaded virtual disk is functioning properly; and

transferring the virtual disk to a customer of the service provider network if the virtual disk is functioning properly.

9. The method of claim 8, wherein determining that the downloaded virtual disk is functioning properly comprises:

converting the virtual disk to a format for the service provider network;

determining whether the virtual disk is bootable; and

booting the virtual disk if the virtual disk is bootable.

10. The method of claim 4, further comprising:

determining that the virtual disk file has a number of virtual disks therein based on the downloaded header;

downloading a portion of each virtual disk;

determining types of the virtual disks by analyzing the downloaded portion of each virtual disk for characteristics that correspond to predetermined signatures for virtual disks;

determining whether the virtual disks are supported by the service provider network based on the types of the virtual disks; and

downloading the virtual disks through the communication network if the virtual disks are supported by the service provider network.

11. The method of claim 10, further comprising:

downloading a footer of each virtual disk through the communication network;

performing integrity checks on the virtual disks based on the footer of each virtual disk; and

downloading the virtual disks through the communication network if the virtual disks pass the integrity checks.

12. A system, comprising:
