Systems and methods for determining the state of a virtual router instance. An example method comprises: monitoring, by a processing device of a host computer system, a network interface associated with an instance of a virtual router; responsive to determining that a certain IP address has been assigned to the network interface, identifying a state of the instance of the virtual router as a master state; and transmitting a message identifying the state of the instance of the virtual router.

Determining state of virtual router instance

An initiation of a network device on a host system may be detected and an IP address may be assigned to the network device. Furthermore, a network gateway may be associated with the IP address. In some embodiments, a network may be assigned to the network device. The network may be configured to route outgoing data from the network through the network gateway as opposed to a default network gateway.

Reactive source routing associated with a network

An occurrence of an event associated with a computing device is identified. A script associated with the identified event is identified. A property of a component that is associated with the computing device is received, wherein the property includes an operating status of the component associated with the computing device. The script is executed for the computing device in view of the operating status of the component.

Execution of a script based on properties of a virtual device associated with a virtual machine

An event associated with a virtual machine may be identified. Furthermore, a script associated with the event may be identified. A property of a virtual device that is assigned to the virtual machine may be received. A determination may be made to execute the script or not to execute the script for the virtual machine based on the property of the virtual device that is assigned to the virtual machine.

Systems and methods for providing Open Systems Interconnection (OSI) layer 3 highly-available routers. An example method comprises: receiving a request to create a highly-available (HA) virtual router; configuring a HA virtual router to run on a plurality of network nodes, the HA virtual router comprising a master instance and a plurality of standby instances; assigning a floating Internet Protocol (IP) address associated with the virtual router to an internal network interface of the master instance; responsive to detecting a failure of the master instance of the HA virtual router, identifying a standby instance to act as a new master instance; and assigning the floating IP address to an internal network interface of the new master instance.

Systems and methods for managing networking activities of a multi-tenant cloud computing environment. An example method may include distributing, by a controller node executed by a processing device, a dynamic host configuration protocol (DHCP) agent to each of a plurality of compute nodes of a computing environment; identifying, by the controller node, a first virtual machine hosted on a first compute node of the plurality of compute nodes; determining a first DHCP agent associated with the first virtual machine and the first compute node; and transmitting, by the controller node, networking information relating to the first virtual machine to the first DHCP agent hosted by the first compute node.
