== 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 problemnetwork connection:
# '''Is it network on VM plugged 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 it turned onthe 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 IP address?''' Run '''ip address''' to check.
# '''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 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 google.ca?''' Run '''host google.ca'''. If it the output doesn't come back with provide an IP address, and all of the above worked - check that your DNS server is configured correctly and that you can ping itthat address.<br><br>There are a number of other problems that could prevent your network connection from functioning but the above are the most common problems.
