In view of the above objectives, a first aspect of the embodiments of the present invention provides an embodiment of a method for improving performance of a virtualized network.

Fig. 2 is a schematic diagram illustrating another embodiment of a method for improving performance of a virtualized network according to the present invention. As shown in fig. 2, a method for improving performance of a virtualized network according to an embodiment of the present invention includes:
when the Virtual Machine interacts with the outside, network data can pass through the Virtual Machine (Virtual Machine), the Hypervisor and the Host Machine (Host Machine). Under the condition that hardware conditions are not upgraded, the performance of a Virtual network is improved by configuring network cards of a Virtual Machine (Virtual Machine), a Hypervisor, a Virtual Machine (Virtual Machine) and a Host Machine (Host Machine).
The management platform monitors the use condition of the Host Machine (Host Machine) CPU core, and when there is a Virtual Machine (Virtual Machine) to be operated, the management platform distributes corresponding core amount from the Host Machine (Host Machine) CPU core through the number of the CPU cores required by the Virtual Machine to be operated so as to supply the Virtual Machine (Virtual Machine) to be operated. When the Host Machine (Host Machine) performs binding operation, the Host Machine preferentially selects from unbound CPU cores, and the CPU core occupied by the Virtual Machine (Virtual Machine) with higher priority than the Virtual Machine (Virtual Machine) to be operated is not occupied as much as possible so as to ensure that the high-priority Virtual Machine (Virtual Machine) is distributed with enough resources. When the number of unbound CPU cores is insufficient, the CPU core number occupied by the Virtual Machine (Virtual Machine) with low priority is removed according to the actual situation, and the Virtual Machine (Virtual Machine) to be operated is bound on the unbound CPU core and the unbound CPU core according to the required CPU core amount. In practical application, a mode of isolation and binding can be selected to bind the virtual machine to be run on the CPU core of the host. Modifying the starting parameters of the GRUD according to the CPU core quantity required by the Virtual Machine (Host Machine) to be operated so as to isolate a part of corresponding CPU cores on the Host Machine (Host Machine), and then binding the process of the Virtual Machine (Host Machine) to be operated to the isolated CPU cores so that the Virtual Machine (Host Machine) to be operated can monopolize the CPU resources. It can be understood that, in practical applications, a direct-binding non-isolation manner may also be selected, which enables the Virtual Machine (Virtual Machine) process to run on the designated CPU core of the Host Machine (Host Machine), so as to reduce the performance loss caused by context switching, and meanwhile, other processes of the Host Machine (Host Machine) may still be scheduled on these CPU cores, which takes into account the performance of the Virtual Machine (Virtual Machine) and the Host Machine (Host Machine).
Bridging a network card of a Virtual Machine (Virtual Machine) to be operated to a network card of a Host Machine (Host Machine), and driving by using the Virtual IO-Net. The method comprises the steps of starting GSO (general Segmentation Offload) and GRO (general reception Offload) of a network card of a Host Machine (Host Machine), and carrying out fragmentation and aggregation of data through the network card of the Host Machine (Host Machine). Under the condition of network card hardware support, the gso (generic Segmentation offload) and gro (generic Receive offload) functions can be directly realized by the network card, otherwise, the functions are processed by the network card driver. Further, by referring to the gso (generic Segmentation offload) and gro (generic reception offload) principles of the network card of the Host Machine (Host Machine), gso (generic Segmentation offload) and gro (generic reception offload) are configured and simultaneously started in the Virtual Machine (Virtual Machine) to be run, and gso (generic Segmentation offload) defer the data fragmentation to the point before the network card sent to the Virtual Machine (Virtual Machine) to be run, and the gro (generic Segmentation offload) aggregates the data received by the network card of the Virtual Machine (Virtual Machine) and then transfers the aggregated data to the network protocol stack. Meanwhile, the Host Machine (Host Machine), the Virtual Machine (Virtual Machine) to be operated and the MTU (Maximum Transmission Unit) on the network link node of the operating environment are adjusted to be consistent, the MTU (Maximum Transmission Unit) of the network cards of the Virtual Machine (Virtual Machine) to be operated and the Host Machine (Host Machine) can be adjusted through the Ethtool, and multiple fragmentation and aggregation caused by the inconsistency of the link node MTU (Maximum Transmission Unit) during Transmission of the network large packet are avoided. By performing linkage configuration on the Host (Host Machine) and the GSO (general Segmentation off flow), the GRO (general reception off flow) and the MTU (maximum Transmission Unit) of the Virtual Machine (Virtual Machine) to be operated in the above manner, network loss can be effectively avoided.
In the aspect of improving the performance of the Hypervisor network, the front end and the rear end of VirtiO-Net are optimized to further improve the performance of the Hypervisor network. The VirtiO-Net front end is driven by a Virtual network card in a Virtual Machine (Virtual Machine), the back end is realized in a Hypervisor, the VirtiO-Net front end and the VirtiO-Net front end exchange data through a data buffer area, and in practical application, a ring buffer area can be selected as the data buffer area for the VirtiO-Net front end and the Hypervisor to exchange data. The transmission efficiency between the front end and the back end of the Virtual Machine-Net is a bottleneck of the network performance of the Virtual Machine (Virtual Machine). By increasing threads for reading and writing data from the data buffer area by the front end and the rear end of VirtiO-Net and enlarging the annular buffer area, the network transmission performance of the front end and the rear end of VirtiO-Net can be effectively improved, namely the transmission efficiency of network data on a Hypervisor layer is improved.
