The network adapter type and virtual network performance optimization in VMware and VirtualBox recently found that the network performance of the Virtual Machine encountered a bottleneck, so I tried to find out that I have always ignored this knowledge, so take a note. 1. vi
Document directory Network Type Kernel Driver Recently, I found that the network performance of the virtual machine has encountered a bottleneck, so I want to find out that I have ignored this knowledge, so I took a note.1. VirtualBox Eshizhan is commonly used in VirtualBox, hereinafter referred to as Vbox. Start with it:
Many netizens have encountered this problem. In win7, the computer is shared as a WiFi hotspot, but the WiFi hotspot (usually wireless connection 2) cannot be connected to the Internet ,: If you encounter such a problem, it must be that the connection you normally access is not correctly shared. For example, your computer is currently using a local connection to connect to the Internet, if you want to use your mobile phone to connect to wireless network
We know that vmware workstation provides many virtual devices. By using these devices, we can build a typical bridging network, host-only network, and Nat network, you can also build complex custom networks. This article aims to let everyone know and master the various network
eight virtual PCI NICs for each virtual machine. For each type of virtual Nic, you can choose one of the following six network hardware types:AMD PCNet pci ii (Am79C970A)AMD PCNet fast iii (Am79C973, the default)Intel PRO/1000 MT Desktop (82540EM) (Windows Vista and later v

first, identify all types of network equipment and network Connections Because network virtualization adds a lot of virtual network devices (including virtual NICs) to the physical machine, the situation becomes complex, so first
LWIP Network Interface network card initialization to STM32 as an example will be useful after 2G or 4G module in the form of PPP dial-up virtual network card, so first of all, this is the premiseLWIP has a structure that describes the physical interface of the Netif Struct, the great god of Chu has a detailed explanat
Network topology With the tap device and Veth pair, we can look at the network of OpenStack compute nodes. First, the virtual machine connects Linux bridge through the TAP device Secondly, the interworking between Linxu Bridge and OvS Bridge is realized through Vethpair Finally, the two-layer network interoperabilit
By default, the virtual network card of VMware Workstation uses two network segments (corresponding to the first network card vmnet1 and the second network card vmnet8) in the range of 192.168.1.0-192.168.254.0 ). The network segm
Problem background: A long time useless notebook, suddenly brought back to use when the SECURECRT unable to connect to the virtual machine Linux problem, has also encountered this problem, basically this problem is caused by the following: 1. Virtual machine Linux firewall is not closed; 2. Virtual machine Linux does not have SSH service installed; 3.
Shared guard version 2.0 has added many features. The most important one is that it can provide automatic host switch. In order to ensure the implementation of the host switching function, the configuration is much more complicated than Version 1.0, especially when users use the fixed IP Mode of a single Nic, the concept of the virtual network card and the virtual
First of all, why use NET to share the host on the outside network, because the notebook often carry, and the company or the home network is the way of DHCP, the use of bridge is not very convenient, each need to change the address, not conducive to environmental configuration, and the service behind the building ...1. In the first step, we need to configure VMware to set the net mode for the
