Abstract

A processing device of a data center may receive a request to run a virtual machine. Responsive to determining that the virtual machine comprises a virtual network interface card (VNIC) associated with a VNIC profile that comprises a pre-defined custom property, the processing device may identify a network to be associated with the VNIC. The processing device may then associate the VNIC with the identified network.

First claim

What is claimed is:

1. A method comprising:
receiving, by a processing device, a request to run a virtual machine, the request comprising a network selection policy;
identifying a virtual network interface card (VNIC) associated with the virtual machine;
selecting, by the processing device, in view of the network selection policy, a network from a pool of networks identified by a property specified by a VNIC profile associated with the VNIC, wherein the property defines a prefix shared by identifiers of networks comprised by the pool of networks and wherein the network selection policy defines a first probability of selecting a first network and a second probability of selecting a second network; and
associating the VNIC with the network.

2. The method of claim 1 , further comprising running the virtual machine.

3. The method of claim 1 , wherein the property references a list of network identifiers.

4. The method of claim 1 , wherein the property specifies a parameter shared by networks comprised by the pool.

5. The method of claim 1 , wherein the network selection policy further defines a uniform distribution of traffic among the plurality of logical networks.

6. The method of claim 1 , wherein the network selection policy further defines an order of networks.

7. The method of claim 1 , wherein the first probability is different from the second probability.

8. A system comprising:
a memory; and
a processing device operatively coupled to the memory, the processing device to:
receive a request to run a virtual machine, the request comprising a network selection policy;
identify a virtual network interface card (VNIC) associated with the virtual machine;
select, by the processing device, in view of the network selection policy, a network from the pool of networks identified by a property specified by a VNIC profile associated with the VNIC, wherein the property defines a prefix shared by identifiers of networks comprised by the pool of networks and wherein the network selection policy defines a first probability of selecting a first network and a second probability of selecting a second network; and
associate the VNIC with the network.

9. The system of claim 8 , wherein the property references a list of network identifiers.

10. The system of claim 8 , wherein the property specifies a parameter shared by networks comprised by the pool.

11. The system of claim 8 , wherein the network selection policy further defines a uniform distribution of traffic among the plurality of logical networks.

12. The system of claim 8 , wherein the network selection policy further defines an order of networks.

13. The system of claim 8 , wherein the first probability is different from the second probability.

14. A non-transitory computer-readable medium having instructions encoded thereon which, when executed by a processing device, causes the processing device to:
receive, by the processing device, a request to run a virtual machine, the request comprising a network selection policy;
identify a virtual network interface card (VNIC) associated with the virtual machine;
select, by the processing device, in view of the network selection policy, a network from the pool of networks identified by a property specified by a VNIC profile associated with the VNIC, wherein the property defines a prefix shared by identifiers of networks comprised by the pool of networks and wherein the network selection policy defines a first probability of selecting a first network and a second probability of selecting a second network; and
associate the VNIC with the network.

15. The non-transitory computer-readable medium of claim 14 , wherein the property specifies a parameter shared by networks comprised by the pool.

16. The non-transitory computer-readable medium of claim 14 , wherein the property references a list of network identifiers.

17. The non-transitory computer-readable medium of claim 14 , wherein the first probability is different from the second probability.
