There are many factors that cause virtual machines to fail to connect to the Internet, including network adapter problems, improper configuration, and deviations in network connection methods. The solution is to carefully examine the network adapter and its associated settings, verify and adjust the network configuration, restart the host device if necessary, and even explore more possibilities.
1. Network adapter is paralyzed
1. The virtual machine network adapter may fail due to software or hardware problems.
2. At this time, you need to check the network card status in the virtual machine manager, and choose to restart the network module or restore the default settings to repair it, as appropriate.
3. If the problem persists, temporarily disable or replace the adapter, and then restart the system.
2. Virtual machine configuration issues
1. Due to improper operation, the virtual machine network configuration is incorrect, causing network connectivity obstacles.
2. Common problems such as: when the VMware virtual machine uses NAT mode, the virtual network card VMnet8 is inadvertently closed; or under the Linux system, there is a deviation in the IP address configuration automatically assigned by the local dhcp.
3. The solution is: readjust the network configuration, enable virtual machine NAT mode or select bridge mode.
3. Improper network settings
1. The network connection mode also has an important impact on the network performance of the virtual machine, such as Host-only and NAT connection modes.
2. Under Host-only connection, the virtual machine can only access the local network and cannot directly access the external network.
3. The NAT connection is available only when the host shuts down the network. Therefore, it is particularly important to correctly set the network connection mode.
