Abstract

A provisioning server receives a reserve command with a set of criteria and searches for a host matching the criteria. Upon finding such a host, the provisioning server reserves the host for performing a virtualization test. Upon receiving or generating a release command, the provisioning server releases the host.

Claims

1. A method comprising:

receiving, by a virtualization system over a network, a reserve command requesting reservation of a host matching a set of criteria;

determining that a host is available and matches the set of criteria;

reserving the host;

performing a virtualization test using the host; and

releasing the host.

2. The method of claim 1, wherein the reserve command comprises data indicative of a reserve reason and wherein reserving the host comprises changing a reserved parameter to indicate the reserve reason.

3. The method of claim 1, wherein reserving the host comprises changing a reserved parameter from a first value to a second value and wherein releasing the host comprises changing the reserved parameter from the second value to the first value.

4. The method of claim 1, wherein releasing the host comprises releasing the host in response to receiving a release command.

5. The method of claim 1, wherein determining that a host is available comprises checking a value of a reserved parameter.

6. The method of claim 1, wherein determining that the host is available and matches the set of criteria comprises determining that the host is available and matches at least some of a set of preferred criteria.

7. The method of claim 1, wherein determining that the host is available and matches the set of criteria comprises:

searching at a first time for an available host matching the set of criteria;

determining, after searching at the first time and before searching at a second time, that no available hosts match the set of criteria; and

searching, at the second time, for an available host matching the set of criteria.

8. A non-transitory computer-readable medium having instructions encoded thereon which, when executed by a processing device, cause the processing device to perform operations comprising:

receiving, by a virtualization system over a network, a reserve command requesting reservation of a host matching a set of criteria;

determining that a host is available and matches the set of criteria;

reserving the host;

performing a virtualization test using the host; and

releasing the host.

9. The non-transitory computer-readable medium of claim 8, wherein the reserve command comprises data indicative of a reserve reason and wherein reserving the host comprises changing a reserved parameter to indicate the reserve reason.

10. The non-transitory computer-readable medium of claim 8, wherein reserving the host comprises changing a reserved parameter from a first value to a second value and wherein releasing the host comprises changing the reserved parameter from the second value to the first value.

11. The non-transitory computer-readable medium of claim 8, wherein releasing the host comprises releasing the host in response to receiving a release command.

12. The non-transitory computer-readable medium of claim 8, wherein determining that a host is available comprises checking a value of a reserved parameter.

13. The non-transitory computer-readable medium of claim 8, wherein determining that the host is available and matches the set of criteria comprises determining that the host is available and matches some of a set of preferred criteria.

14. The non-transitory computer-readable medium of claim 8, wherein determining that the host is available and matches the set of criteria comprises:

searching at a first time for an available host matching the set of criteria;

determining, after searching at the first time and before searching at a second time, that no available hosts match the set of criteria; and

searching, at the second time, for an available host matching the set of criteria.

15. A virtualization system comprising:

a memory to store information regarding a plurality of hosts;

a processing device, coupled to the memory, to;

receive, over a network, a reserve command requesting reservation of a host matching a set of criteria;

determine that a host of the plurality of hosts is available and matches the set of criteria;

reserve the host;

perform a virtualization test using the host; and

release the host.

16. The system of claim 15, wherein the reserve command comprises data indicative of a reserve reason and wherein reserving the host comprises changing a reserved parameter to indicate the reserve reason.

17. The system of claim 15, wherein the processing device is to reserve the host by changing a reserved parameter associated with the host in the memory from a first value to a second value and to release the host by changing the reserved parameter from the second value to the first value.

18. The system of claim 15, wherein the processing device is to release the host in response to receiving a release command.

19. The system of claim 15, wherein the processing device is to determine that the host is available by checking a value of reserved parameter associated with the host in the memory.

20. The system of claim 15, wherein the processing device is to determine that the host is available and matches the set of criteria by determining that the host is available and matches some of a set of preferred criteria.
