Windows 7 vmwarevirtual machine cannot be connected to the Internet to solve the configuration that has been tossing for nearly an hour, so it is easy to vomit. Although there is no definite reason, it can be used as a reference. After that, we Installed VMware Workstation 9 on a friend's windows 7 family edition, but Ubuntu in VMware could not connect to the Internet, so we launched an untitled troubleshooting. Why is the host network disconnected? This is the simplest reflection, and the host network is normal. Is there a problem with the Ubuntu copy? Because I have installed Ubuntu on VMware, the first idea is that there may be problems with copying images from the past in order to copy them directly to a friend's VMware. This is unlikely because it is similar to copy once in the company and runs normally. However, after troubleshooting, I re-installed a Ubuntu on my friend VMware, but it still cannot be connected to the Internet. Is Windows 7 Home Edition compatible with VMware? I checked it online. Why is the VMware Virtual Network Card not loaded? Restart the host. Is there a problem with the user permission? Because I created a new Windows account after installing VMware, and then used this account to log on to the host, and then run VMware, no new account can access the VMware installed in other accounts? So I re-Installed VMware under my new account. OK. This is normal. Summary After VMware is normal, you can log on to Windows with your original account. Ubuntu in the virtual machine can also be connected to the Internet normally. I think that it is normal after VMware cannot be reinstalled online, so it should be because the virtual network card is not properly installed when VMware is installed first, rather than the account permission. The NIC is the driver layer, and it is difficult to interact with the account. The two are not at the same level. In addition, my friend's sub-system is messy, and it is quite likely that the driver is not installed in VMware once. Therefore, it makes sense to say that the network management trick is: "restart the host if there is a problem, and reinstall the system if there is no problem ."
