    Hyper-v default switch issue

    by larsulf ·

    Hi everyone. I have a question about my default switch in Hyper-V. I was editing some info in the IPv4 which is what I believe, the cause of my current problems. Basically I misunderstood some school-task, and ended up deleting the already set-up IP and DNS from Default switch -> Setup -> IPv4 -> IPv4 Setup. So basically activating DHCP. Before this, the network inside the VM had no issue. Any idea how to fix this? Been googling, asking fellow students and teachers.

    Tried deactivating Hyper-V and reinstalling it.

    Any suggestions are warmly welcomed!

      If you accidentally deleted the IP and DNS settings for your Hyper-V Default switch, you can try the following steps to restore the settings:

      Open the Hyper-V Manager on your Windows host computer.

      Right-click on the Default switch and select “Properties.”

      Select the “IPv4 Address” tab and check the box for “Use the following IP address.”

      Enter the IP address, subnet mask, and default gateway that were previously configured for the Default switch.

      Select the “DNS server” tab and check the box for “Use the following DNS server addresses.”

      Enter the primary and secondary DNS server addresses that were previously configured for the Default switch.

      Click “OK” to save the changes.

      If the above steps don’t work, you can also try resetting the Default switch to its default settings:

      Open the Hyper-V Manager on your Windows host computer.

      Right-click on the Default switch and select “Remove.”

      Click “Yes” to confirm the removal of the Default switch.

      Right-click on the host computer in the Hyper-V Manager and select “Virtual Switch Manager.”

      Click “New virtual network switch” and select “Default switch.”

      Click “Create virtual switch” to create a new Default switch with default settings.

      Once you have created the new Default switch, you can configure the IP and DNS settings as required. Note that resetting the Default switch will remove any existing virtual machines that were connected to it, so you may need to recreate them if necessary.

      If you have deleted the static IP and DNS settings for the Default switch in Hyper-V, and enabled DHCP, you will need to configure the network settings in your virtual machines to obtain IP addresses automatically from the Default switch’s DHCP server. Here are the steps to do this:

      Open Hyper-V Manager and select the virtual machine that you want to configure.
      Right-click on the virtual machine and select “Settings”.
      In the Settings window, select “Network Adapter” and click “Advanced Features”.
      In the “Advanced Features” window, select “Enable virtual LAN identification” and set the VLAN ID to “0”.
      Click “OK” to close the “Advanced Features” window, and then click “OK” again to close the “Network Adapter” settings window.
      Start the virtual machine and go to the network settings. Set the network connection to “Obtain an IP address automatically” and “Obtain DNS server address automatically”.
      Save the changes and restart the virtual machine.
      These steps should allow the virtual machine to obtain an IP address and DNS server information from the Default switch’s DHCP server, and should restore the network connectivity inside the virtual machine.

      Hyper-V and enabled DHCP instead, which is causing connectivity issues within your VM. Here are a few suggestions that may help you fix the issue:

      Try resetting the default switch settings to their default values by right-clicking on the default switch in Hyper-V Manager and selecting “Properties”. From there, click on “Virtual Switch Manager” and then select “Restore Defaults”. This should set the default switch back to its original configuration.

      If the first solution doesn’t work, try manually configuring the IP address and DNS settings for the default switch. To do this, go to “Properties” -> “Virtual Switch Manager” -> “Default Switch” -> “Properties” -> “IPv4 Address” and select “Static”. Then enter the IP address, subnet mask, default gateway, and DNS server addresses as necessary.

      Check your VM’s network settings to make sure they are configured correctly. If you are using a static IP address for your VM, ensure that the IP address, subnet mask, default gateway, and DNS server addresses are all correct. If you are using DHCP, make sure that the VM is set to obtain an IP address automatically.

      Ensure that your host machine’s network settings are configured correctly. Check that the network adapter is enabled, and that it is set to obtain an IP address automatically if you are using DHCP.

      If none of the above solutions work, try uninstalling and reinstalling the network adapter driver on your host machine.

      I hope one of these solutions helps you fix your issue. Good luck!

      It seems that you have accidentally deleted the manually assigned IP address and DNS settings from the Default switch in Hyper-V, and now the VMs are not able to communicate with the network. To resolve this issue, you can try the following steps:

      Open the Hyper-V Manager and select the Default Switch.

      Click on the Virtual Switch Manager option in the Actions pane.

      In the Virtual Switch Manager, select the Default Switch and click on the Properties button.

      In the Properties window, select the IPv4 tab and click on the Edit button.

      In the Edit IP Address Settings window, select the “Use the following IP address” option and enter the IP address, subnet mask, and default gateway details.

      Next, click on the DNS tab and enter the DNS server address.

      Click OK to apply the changes and exit the Properties window.

      Restart the virtual machines to apply the changes.

      Once the virtual machines have restarted, they should be able to communicate with the network. If you still face any issues, you may need to check the network settings of the virtual machines to ensure they are configured correctly.

      The Hyper-V Default Switch is a virtual switch created by Hyper-V during installation, which allows virtual machines to connect to the host system and the network. If you are experiencing issues with the Hyper-V Default Switch, there are a few troubleshooting steps you can try:

      Check if the Default Switch is enabled: Go to Hyper-V Manager and select Virtual Switch Manager. Ensure that the Default Switch is listed and that it is enabled.

      Check the network adapter settings: Open the Settings app and navigate to Network & Internet > Ethernet (or Wi-Fi) > Change adapter options. Right-click on the virtual adapter for the Default Switch and select Properties. Ensure that the necessary protocols and services are enabled.

      Check the firewall settings: Ensure that the Windows Firewall is configured to allow traffic for the virtual adapter associated with the Default Switch.

      Update the network adapter driver: Ensure that the network adapter driver on the host system is up to date.

      Reset the Default Switch: You can try resetting the Default Switch by deleting it from the Virtual Switch Manager and recreating it.

      If none of these steps resolve the issue, it may be necessary to consult with a more experienced Hyper-V administrator or contact Microsoft support for further assistance.

      It sounds like you accidentally deleted the static IP address configuration for your Hyper-V default switch and activated DHCP. To fix this issue, you can try the following steps:

      Open the Hyper-V Manager on your computer.
      Select the Virtual Switch Manager from the Actions pane on the right side of the screen.
      Select the Default Switch from the list of virtual switches.
      Click on the Properties button to access the network adapter settings for the Default Switch.
      Select the IPv4 tab and choose the radio button for “Use the following IP address”.
      Enter the correct IP address, subnet mask, and default gateway values for your network.
      Scroll down to the DNS settings and enter the correct DNS server addresses.
      Click OK to save the changes.
      After you have made these changes, the network inside your VM should be able to communicate properly again. If you continue to have issues, it may be necessary to check the network settings for your virtual machines as well.

      If you accidentally deleted the IP and DNS settings for your Hyper-V default switch, causing network issues in your virtual machine, there are a few things you can try to fix the problem:

      Check that DHCP is properly configured: If you activated DHCP, make sure that it is properly configured in your virtual machine. Check that your VM is receiving an IP address from the DHCP server, and that the DNS settings are also correct.

      Check the default switch settings: Make sure that the default switch is properly configured in Hyper-V Manager. Check the virtual switch settings to ensure that the correct network adapter is selected and that the switch type is set to external.

      Reset the default switch settings: If you are unsure what settings you may have changed, you can reset the default switch settings back to their default values. To do this, right-click on the default switch in Hyper-V Manager and select “Remove”. Then, right-click on the Hyper-V server name and select “Virtual Switch Manager”. Re-create the default switch with the appropriate settings.

      Check network adapter settings: In your virtual machine settings, ensure that the network adapter is connected to the correct virtual switch and that the virtual switch is set to external.

      If none of the above steps work, you may need to seek further assistance from your school’s IT department or a Hyper-V expert.
