Virtual machine network loss detection and recovery for high availability

A non-transitory computer-readable medium storing instructions, which when executed by a processing device, cause the processing device to perform a method comprising:

• determining that a first physical network interface controller of a first host computer has lost a client traffic network connection, wherein at least one data compute node running on the first host computer has client traffic transmitted via the client traffic network connection;
• identifying, in response to the loss of the client traffic network connection, one or more host computers each having a physical network interface controller with a functioning network connection for the client traffic;
• and
• moving, further in response to the loss of the client traffic network connection, the data compute node to one of the identified host computers, wherein the first host computer utilizes a second physical network interface controller to move data compute node.

An apparatus comprising:

• a processing device;
• and
• a memory coupled to the processing device, the memory storing instructions which, when executed by the processing device, cause the apparatus to:
• determine that a first physical network interface controller of a first host computer has lost a client traffic network connection, wherein at least one data compute node running on the first host computer has client traffic transmitted via the client traffic network connection;
• identify, in response to the loss of the client traffic network connection, one or more host computers each having a physical network interface controller with a functioning network connection for the client traffic;
• and
• move, further in response to the loss of the client traffic network connection, the data compute node to one of the identified host computers, wherein the first host computer utilizes a second physical network interface controller to move data compute node.
