Linux Network Connection Configuration Troubleshooting
If the network works in your host, but not in your Virtual Machine, you should perform the following routine steps to troubleshoot the network connection:
# '''Is network on IS THE NETWORK ON VM plugged inPLUGGED IN?''' On a physical network you would check whether the cable is plugged in and the link light is on on your network card. In a virtual network environment, you don't have a physical network adapter. Instead, you will need to check the NIC settings in the <u>'''virtual'''</u> machine details to view and confirm the appropriate network connection.# '''Is the network enabledIS THE NETWORK ENABLED?''' This is a problem more common with virtual networks than physical networks. Check in your '''VirtManager'''->'''ConnectionDetails'''->'''VirtualNetworks''' that your network is active.# '''Do you have an DO YOU HAVE AN IP addressADDRESS?''' Run '''ip address''' to check.# '''Can you ping the host by CAN YOU PING THE HOST BY IP?''' (by its internal IP address). If not - check all of the above, check if you have an IP address conflict, and check that your subnet mask is correct.# '''Can you ping CAN YOU PING 8.8.8.8?''' If all of the above work - check that your default gateway is set correctly with '''ip route''' and that you can ping the default gateway.# '''Can you resolve CAN YOU RESOLVE google.ca?''' Run '''host google.ca'''. If the output doesn't provide an IP address, check that your DNS server is configured correctly and that you can ping that address.
There are a number of other problems that could prevent your network connection from functioning but the above are the most common problems.
