Error while setting the bridge interface

[PazDim]

Hello. I'm trying to configure a virtual machine's access to the Internet. The computer has the CentOS operating system installed. The version of VirtualBox is 5.1 (also tried 5.2). The computer has two interfaces: ethernet and WI-FI. I need to configure the bridge connection. With ethernet, everything works fine: the virtual machine gets the address from the router and has access to the Internet. But the target interface is WI-FI. When I configure a bridge connection with WI-FI and start the virtual machine, an error occurs:

Code: Select all

VBoxManage: error: Failed to open/create the internal network 'HostInterfaceNetworking-wlsl' (VERR_INTNET_FLT_IF_NOT_FOUND).
VBoxManage: error: Failed to attach the network LUN (VERR_INTNET_FLT_IF_NOT_FOUND)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole

I read that in Windows it is necessary to enable the NDIS driver for the network interface. But how to do it in Linux?

Please provide a VM log file. With the VM fully shut down, right click it in the GUI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

Thanks for the answer. Sorry, I have no GUI (CentOS minimal). In the virtual machine directory there is a directory called Logs, it contains VBuxHardening.log, VBox.log, VBox.log.1, VBox.log.2... files. Which of these files is needed?

Which of these files is needed?

I would go with the one called VBox.log as that is the one mpack asked for!

I made a backup of the old files and started a new log file. The name of the Wi-Fi network interface is "wlsl".

The error seems to indicate that you're bridging to a network which doesn't exist. Why not try changing the networking type to NAT? (in the VM settings).

Other things I see:

• 5.1.38 is rather old, consider upgrading.
• 3GB is way too much to be giving to the VM on your host, which only has 3.3GB free, and needs to run other stuff besides your VM. I'd reduce to 2GB.
• 27MB is not much graphics RAM for a desktop OS. I'd increase to 64MB.
• 1 core will give poor performance, you could have afforded 2.

Thanks for the answer. The network exists - through Wi-Fi, I control the computer. I tried to configure NAT, but I could not create a virtual adapter. A virtual machine must have Internet access, and other computers should be able to join it. With a bridge connection, the router assigns an address to the virtual machine and it is visible to other computers. In the case of NAT, I need to configure iptables, but this requires a virtual adapter, right?
1. I tried version 5.2. The error was different (I do not remember which one), but it also did not start;
2. The host has 4 GB of RAM, the virtual machine is used for the game server - it needs more memory. Yesterday I tested the whole day through another network interface, everything worked fine;
3. I do not think that there is a need for this - the computer does not have a display;
4. Thank you, I'll try.

Increased the number of cores, it seems to be better. So what can you do with the network?

Please read the following: User Manual, ch. 6.2. Introduction to networking modes including the Overview table, which shows quickly what kind of connection is required to achieve what you want. And remember, you can always have more than one network card in your guest to cover multiple scenarios.

Thank you. I understand correctly, I need NAT (not NAT network) and port forwarding? I'll try to do so.

So, everything worked on Windows. I configured NAT and port forwarding and tried to connect to 127.0.0.1. The connection was redirected to the virtual machine. But on Linux host port forwarding does not work. Virtual Machine Configuration File:

In network connections, a second network interface appeared. How do I know if port forwarding works?

Yes! I did it! Just turned off the CentOS firewall. Thank you all for your help!
