Recently in VMware to do ha double-click Hot Standby Experiment, the first network card is set to bridge mode, the second network card is set to NAT, the first NIC can get the address, the second NIC cannot get to the DHCP address, change to static address also not, the solution:Add a line of code to the two NICs:Nm_controlled= "No" This line of code means not to let NetManage management network card, resta

Installing ESXi prompts in a VMware Workstation virtual machine does not find the NICOverview: Today, a netizen asked me, said in the VMware Workstation virtual machine, the installation ESXi prompt cannot find the network card. At first I thought he had a wrong procedure, and later learned that his steps were correct, the problem was that the image of ESXi was used, and after the image was re-downloaded, the problem was resolved.passers-by Krabi 2016/4/1215:32:53Miss Wang, hello.Esxi6 The

TUN/TAP provides the reception and transmission of packets to the user-space program, which can be viewed as a simple point-to-point device orEthernet devices. It receives the package from the user-space program instead of receiving the package from the physical device. It sends packets not through objectsTo send packets to a user-space program.In order to apply this driver, the application needs to open the/dev/net/tun device (character device) and then issue a controlSystem (IOCTL) to register

Now the general enterprise will use dual-card access, so that both the network bandwidth can be added, while the corresponding redundancy can be said to be a lot of benefits. And the general enterprise will use the Linux operating system comes with the network card binding mode, of course, now the network card manufacturers will also be some for the Windows operating system network card management software to do network card binding (Windows operating system does not have a network card binding

The Xen virtual opportunity defaults to bind the network adapter to the XENBR0,So if you need to switch to a different physical NIC, you need to configure the script or execute the command yourself.1. Add Script BindingsA.

this article starting at Slime Line the world . Because of the need to do ESXi-related experiments, you can experiment with VM virtual ESXI on your own machine. Because the experiment requires two NICs, two NICs were added when the ESXi virtual machine was created.

xmit_hash_policy=layer3+4"Note: The Miimon is used for link monitoring. For example: miimon=100, then the system every 100MS monitoring link connection status, if one line is not connected to another line; The value of mode indicates the mode of operation.The mode=0 indicates that load balancing (round-robin) is balanced, and both NICs work. Load-balanced operation mode that provides twice times the bandwidth. In this case, the failure of a network card will only be the server egress bandwidth

VMware cloning Centos6.4 virtual machine NIC does not start problemIn the course of learning, it is found that the following problems cannot be solved. Quickly create a Linux virtual machine version of centos6.4 with the full cloning feature of Vmware8. post-creation symptoms: Use ifconfig after startup, no IP address found, only loopback address is 127.0.0.1, mac address and host name are the same as the source host (IP configured by the source host
