Abstract: Some embodiments provide a method for selecting a transmit queue of a network interface card (NIC) of a host computer for an outbound data message. The NIC includes multiple transmit queues and multiple receive queues. Each of the transmit queues is individually associated with a different receive queue, and the MC performs a load balancing operation to distribute inbound data messages among multiple receive queues. The method extracts a set of header values from a header of the outbound data message. The method uses the extracted set of header values to identify a receive queue which the NIC would select for a corresponding inbound data message upon which the NIC performed the load balancing operation. The method selects a transmit queue associated with the identified receive queue to process the outbound data message.

Abstract: Some embodiments provide a method for managing multiple queues of a network interface card (NIC) of a host computer that executes a data compute node (DCN). The method defines first, second, and third subsets of the queues. The first subset of queues is associated with a first feature for processing data messages received by the NIC, the second subset of queues is associated with a second feature, and the third subset is associated with both features. The method receives a request from the DCN to process data messages addressed to the DCN using both the first and second features. The method configures the NIC to direct data messages received for the DCN to a queue that is selected from the third subset of queues.

Abstract: Embodiments perform decentralized virtual machine (VM) migration decisions. By comparing a set of VM-specific rules with current statistics (e.g., resource usage), one host determines whether to migrate the VM and lazily selects another host to receive the VM. The rules define, for example, threshold values for resource usage. The host makes the migration decision and performs the migration without input from a centralized server. In this manner, migration decisions are offloaded to migration modules executing on each host for reactive and/or proactive migration. Proactive migration involves migrating a VM before the VM violates its rules.

Abstract translation: 实施方式执行分散式虚拟机（VM）迁移决策。 通过将一组VM特定规则与当前统计信息（例如，资源使用情况）进行比较，一个主机确定是否迁移该虚拟机，并且懒惰地选择另一个主机以接收该虚拟机。 规则定义了例如资源使用的阈值。 主机进行迁移决策并执行迁移，无需从集中式服务器进行输入。 以这种方式，迁移决策被卸载到在每个主机上执行的用于反应和/或主动迁移的迁移模块。 主动迁移涉及在VM违反其规则之前迁移VM。

Abstract: A method for managing several queues of a network interface card (NIC) of a computer. The method initially configures the NIC to direct data messages received for a data compute node (DCN) executing on the computer to a default first NIC queue. When the DCN requests data messages addressed to the particular DCN to be processed with a first feature for load balancing data messages across multiple queues and a second feature for aggregating multiple related data messages into a single data message, the method configures the NIC to direct subsequent data messages received for the DCN to a second queue in a first subset of queues associated with the first feature if a load on the default first queue exceeds a first threshold. Otherwise, if a load on the first subset of queues exceeds a second threshold, the method configures the NIC to direct subsequent data messages received for the particular DCN to a third queue in a second subset of queues associated with both the first and second features.
