Abstract

A system for discovering and mitigating out-of-sync network parameters may determine that a first value for a parameter of a set of parameters of a logical network associated with a host computing system is different from a second value specified for the parameter in a network definition. The system may further presenting, via a user interface, the first value and the second value for the parameter and receiving, via the user interface, a confirmation of validity of the first value for the parameter. Responsive to ascertaining validity of remaining parameters of the set of parameters, setting a validity attribute of the logical network.

Claims

1. A method comprising:

determining, by a processing device, that a first value for a parameter of a set of parameters of a logical network associated with a host computing system is different from a second value specified for the parameter in a network definition;

presenting, via a user interface, the first value and the second value for the parameter;

receiving, via the user interface, a confirmation of validity of the first value for the parameter; and

responsive to ascertaining validity of remaining parameters of the set of parameters, setting a validity attribute of the logical network.

2. The method of claim 1, wherein the logical network is implemented by a bridge associated with a network interface card (NIC) of the host computer system.

3. The method of claim 1, wherein the set of parameters comprises one or more of a virtual local area network identifier (VLAN ID), a maximum transmission unit (MTU), a maximum bandwidth, a minimum bandwidth, or an Internet Protocol (IP) address.

4. The method of claim 1, further comprising including the logical network in a management scope of a virtualization manager executed by the processing device in response to receiving the confirmation of validity of the first value of the parameter.

5. The method of claim 1, further comprising storing, in a configuration data store, an indication that the first value of the parameter has been confirmed as valid for the logical network, wherein the indication is stored in association with an identifier of the logical network.

6. The method of claim 1, further comprising:

determining that a third value for a second parameter of the set of parameters is different from a fourth value specified for the second parameter in the network definition;

determining that an automated correction rule applies to a parameter type of the second parameter; and

automatically replacing the third value with the fourth value for the second parameter.

7. The method of claim 1, further comprising:

determining that a third value for a second parameter of the set of parameters is different from a fourth value specified for the second parameter in the network definition;

determining whether a difference between the third value and the fourth value is within a range specified in an automated correction rule;

responsive to the difference between the third value and the fourth value not being within the specified range, automatically replacing the third value with the fourth value for the second parameter; and

responsive to the difference between the third value and the fourth value being within the specified range, refraining from automatically replacing the third value with the fourth value for the second parameter.

8. The method of claim 1, wherein the user interface comprises an indication that the first value is allowed for the parameter.

9. The method of claim 1, wherein receiving, via the user interface, the confirmation of the validity of the first value for the parameter comprises:

presenting, in the user interface, an indication that the first value is not allowed for the parameter, and requesting a user to change the first value; and

receiving user input specifying a third value for the parameter, the third value being closer to the second value than the first value.

10. A system comprising:

a memory device; and

a processing device coupled to the memory device, the processing device to;

determine, by a processing device, that a first value for a parameter of a set of parameters of a logical network associated with a host computing system is different from a second value specified for the parameter in a network definition;

present, via a user interface, the first value and the second value for the parameter;

receive, via the user interface, a confirmation of validity of the first value for the parameter; and

responsive to ascertaining validity of remaining parameters of the set of parameters, set a validity attribute of the logical network.

11. The system of claim 10, wherein the user interface is a graphical user interface (GUI), command line interface (CLI), or application programming interface (API).

12. The system of claim 10, wherein the processing device is further to include the logical network in a management scope of a virtualization manager executed by the processing device in response to receiving the confirmation of validity of the first value of the parameter.

13. The system of claim 10, wherein the processing device is further to store, in a configuration data store, an indication that the first value of the parameter has been confirmed as valid for the logical network, wherein the indication is stored in association with an identifier of the logical network.

14. The system of claim 10, wherein the processing device is further to:

determine that a third value for a second parameter of the set of parameters is different from a fourth value specified for the second parameter in the network definition;

determine that an automated correction rule applies to a parameter type of the second parameter; and

automatically replace the third value with the fourth value for the second parameter.

15. The system of claim 10, wherein the processing device is further to:

determine that a third value for a second parameter of the set of parameters is different from a fourth value specified for the second parameter in the network definition;

determine whether a difference between the third value and the fourth value is within a range specified in an automated correction rule;

responsive to the difference between the third value and the fourth value not being within the specified range, automatically replace the third value with the fourth value for the second parameter; and

responsive to the difference between the third value and the fourth value being within the specified range, refraining from automatically replacing the third value with the fourth value for the second parameter.

16. The system of claim 10, wherein the user interface comprises an indication that the first value is allowed for the parameter.

17. The system of claim 10, wherein to receive, via the user interface the confirmation of the validity of the first value for the parameter the processing device is further to:

present, in the user interface, an indication that the first value is not allowed for the parameter, and requesting a user to change the first value; and

receive user input specifying a third value for the parameter, the third value being closer to the second value than the first value.

18. A non-transitory computer readable medium, having instructions encoded thereon that when executed by a processing device cause the processing device to:

determine that a first value of a parameter of a set of parameters of a logical network associated with a host computing system is different from a second value specified for the parameter in a network definition;

determine whether the first value of the parameter is valid in view of the first value being different from the second value;

upon determining that the first value of the parameter is invalid, update the first value to the second value for the parameter; and

responsive to ascertaining validity of remaining parameters of the set of parameters, set a validity attribute of the logical network.

19. The non-transitory computer readable medium of claim 18, wherein to determine whether the first value of the parameter is valid the instructions further cause the processing device to determine that an automated correction rule applies to a parameter type of the second parameter.

20. The non-transitory computer readable medium of claim 18, wherein to determine whether the first value of the parameter is valid the instructions further cause the processing device to:

determine a difference between the first value and the second value; and

determine whether the difference is within a range specified in an automatic correction rule.
