Virtual machine network adapter is not visible

Hello

I complaint customer that they are not able to get the connectivity, then I checked in troubleshooting vm and not founded then is no network adapter in this machine special vm,

Please suggest what will be the root for this cause.

Kind regards

Hello

I believe that VM used to have a network card installed once?

You can think of your VMS from hardening. By default, each user who has remote access to the VM can eject the NETWORK card using the windows function to eject removable devices. It's what could have happened to your customer.

To avoid this problem, you can add several custom in the vmx file settings. To avoid removing the devices that it would be

isolation.device.connectable.disable = "true"
isolation.device.edit.disable = "true"

for example. But there's more.

Please see the guide to hardening vSphere 5.0: http://communities.vmware.com/docs/DOC-19605

and this tutorial interesting by William on explaining how to strengthen your virtual machines automatically through scripts in vCenter: http://blogs.vmware.com/vsphere/2012/07/automatically-securing-virtual-machines-using-a-vcenter-alarm.html

  • Unable to add the virtual machine network services

    Hello:

    I already read that warning Virtual PC 2007 is not compatible with win 7-64.
    However, I read that it is "unofficially" possible launch.
    OK, I installed it and it worked except networking.
    Basically, I need to install the Virtual Machine Network Services.
    I right click on my network card-> properties-> install-> services-> virtual machine network services (VPC2007 folder: where I can see VMNetSrv.inf)
    Then says Windows: it is impossible to add the requested feature. The specified service has been marked for deletion.

    The problem is that I get this error even on WinXP SP3, so I think that there is something else wrong.

    And of course, Virtual PC 2007 available networks are only: no connection, Local, NAT.  (Missing my physical adapter)

  • The network adapter could not establish the connection using the external ip address

    Hi team,

    Please look in the attached files.

    I installed db 11g on my desktop machine (Windows 7, with a local network) and then I created a data source connection in tomcat which was also in the same system and then I deployed my sample web application, everything works fine, I am able to access web applications.

    But once that I kept my system with external IP address (excluding local network of my company), oracle gives these following errors when tomcat start

    Here is the following URL will display the error during the startup of tomcat.

    The network adapter could not establish the connection,

    In these two files, listener and tnsnames ora ora, need to change the configurations if I change the Ip address of the system?

    even I tried my address keeping external Ip instead if host in these two configuration files, yet this does not work.

    any help would be greatly appreciated!

    Thank you.

    Because as I explained - your listener is listening on localhost only. localhost is never accessible to another machine.

    Stop your listener, change the listener.ora to listen to on the real machine name and start the receiver.

    In addition, your tnsnames.ora points to localhost...

    Stop using localhost, unless you only want things to work on the same machine.

    BIOS bug? I don t think so

    First of all, you must make sure that this isn't a hardware problem. In this case, insert the Toshiba Recovery CD and reinstall the operating system of this device. This will outline the laptop to factory settings. Notes; This would format the whole HARD drive.

    After the new installation, you must activate the WLan switch on the side of books, and you can then use the switch button FN + F8 to select the WiFi network.

    I assume that you have already configured your Wlan router. So the same settings such as the SSID, encryption of WLan, etc. must be defined on the laptop too.

  • "The network adapter is not correctly configured to use the ip Protocol" problem on Vista

    Hello. My PC has recently came across this problem "the network adapter is not correctly configured to use the ip Protocol", every time I click on diagnose & repair. I don't know how to fix it. Please help, thanks in advance. Magic

    Hello X-x_MaGiC_x-X,

    Thank you for visiting the website of Microsoft Windows Vista Community.

    Try the rest of the stage in this article:

    System restore points are created automatically when the following occur:

    • When you install a new application or driver.
    • When you uninstall or install some programs.
    • When you install new updates
    • Automatically on a daily interval
    • Manually by creating a.
    • If you choose to use system restore to restore to a previous restore point, System Restore creates a new restore point before you restore a previous state in case something goes wrong. If you are restoring to a previous state in Mode without failure, a restore point will create for the current state.

    So that the restoration of the system to work, you must have 300 MB of free space for each hard disk that monitors the system restore. System Restore will also use up to 15% of disk space on each disk that it monitors. That hard disk space runs out, older restore points will be deleted as newer ones. It is also important to note that you must be logged in as an administrator in order to use the system restore. Now that you understand the basics of the system restore, you must continue to the next section to learn how to use it.

    Restore Windows Vista to a previous state

    In the case of a problem on your computer that cannot be solved by normal means, you can restore your computer to a previous working state. To do this, you need to start restoring the system so that you can choose the restore point to restore. If you currently have Windows Vista boot problems, you can use the system restore in Windows recovery environment. Instructions on how to do it in this tutorial can be found: System Restore using the Windows Vista recovery environment.

    If you can connect to Windows Vista, you must follow these steps.

    1. Close and save any documents that you have opened.
    2. Click the Start button to open your Start Menu. The Start button looks like this:
    3. When the Start Menu open click on the menu option all programs.
    4. Click once on the Start Menu Accessories group.
    5. Click once on the System Tools Start Menu group.
    6. Click once on the icon of the system restore. After you click the icon, if a user account control window opens, click on the button continue.

    You will now be on the screen as shown below in Figure 1 system restore. From this screen, you can specify the restore point that you want to restore.

    1 screen of system restore

    By default, Vista will be already selected the restore recommended option. This restore point is one followed a new pilot program, or update has been installed. If you do not want to use this restore point, you can click on the button next to start the restore process. On the other hand, if there is a more recent restore point that you want to restore you should select choose a different restore point and press the next button. This will bring you to a screen, as shown in Figure 2, which contains a list of all available restore points that you can restore.

    2. the list of available restore points

    You must select the restore point that you want to restore, and then press the button next to start the restore process. Vista will display a window showing your selected restore point and asking you to confirm that it is that you want to restore.

    3. confirm the selected restore point

    If you want to select a different restore point, press the Back button. Otherwise, you can press the Cancel button to exit the system restore or the button finish to begin the restore process. If you have selected finish, Vista will display a second prompt asking you to confirm that you want to continue restoring.

    4. second Confirmation

    If you are sure you want to restore, then press the Yes button. Vista will now log you off the computer and start the system restore process, as shown in Figure 5 below.

    5. restoration of a restore point

    When the restore is complete, your computer will be restarted and when Vista starts it backup will be restored to its previous state. When you open a Vista session for the first time after the restore, you will see a message indicating that the restore was successful.

    6. system restore was successful

    If there are problems with your computer because the last restoration, you can return to your previous settings to ebb in the system restore utility and select Undo system restore by pressing the next button.

    7 undo the last system restore

    Your computer should now work correctly again.

    With the help of the restoration of the system in the Windows recovery environment

    Manual creation of Restore Points

    As mentioned previously, it is also possible to create manual restore depending on points. Some popular designs to create manual restore points are when you have your computer configured perfectly and I would save the State in case of problems in the future. To create a manual restore point, you must follow these steps:

    1. Click the Start button to open your Start Menu. The Start button looks like this:
    2. Click on the control panel menu option.
    3. Click the option menu system and Maintenance.
    4. Click on the system menu option.
    5. Click on the System Protection in the list on the left.

    You will now be at the System Protection tab in the system control panel. This tab allows you to enable and disable the system restore as well as making the new manual restore points.

    8. the System Protection tab

    To create a manual restore point, you must click on the button create. When you press this button a prompt asking you to give a title to this manual restore point.

    9. Enter the manual restore point title

    Type a title for the manual restore point and press the button create. Vista will now create a restore point manually and once finished, post a notice that it was created successfully.

    10. Manual restore point has been created

    Now that you have finished doing the manual restore point, you can close the system window.

    Try to download the correct and up-to-date drivers.

    This should solve your problem.

    Let us know if these steps solve your problem.  I hope the information is useful.

  • Wireless network adapter is not installed and configured

    I have recently re installed windows vista for my laptop dell inspiron 1545. I am not able to connect to wireless internet, it says that the wireless network adapter is not installed and configured. How do I install it and where can I get the wireless network adapter. I have a cd or anything for it. Thank you

    You can get in trouble with your device drivers, firmware and/or software.  Go to the Device Manager by going to start / find and type Device Manager and enter and then double-click on the program icon that appears.  Check each device to a red x, yellow! or white?  These identify devices with problems probably (drivers, but also of conflict or something else).  Click on each for more details and troubleshooting tips.  If you need to get drivers (and you shouldget from Dell for the wireless adapter at all you have time to do - they can help way beyond simply solve this problem), let the computer dealer or the manufacturer of the device (NOT of Microsoft Updates).  In fact, you must disable automatic updates in Windows Update driver as follows:http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Follow these steps to get the drivers: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm.  Once you have the drivers, you can install them via the Manager device as follows:http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html. > http://support.microsoft.com/kb/244617.

    The adapter is inside the laptop.  You don't need to do something with it to install it.  Install the drivers, firmware or software for it and your version of Vista from Dell (all that apply) "install".  You must then go to start / Control Panel / Network and sharing Center and configure the adapter with the appropriate parameters and to establish the appropriate network connections.  This will take place in settings required by your ISP, and maybe your router or modem (so you may need to contact them if you don't know the settings).

    Here are the procedures for Vista with Windows7 network layout that can help:http://www.windowsnetworking.com/articles_tutorials/Windows-7-Understanding-Network-Administration-Configuration.html.

    (1) what is the user id you are using OEM fior?

    The user id should have Sysdba and should not be in the role SYSASM.

    (2) in order to check your port

    In server, in the gate of the House, listener, lsnrctl status--> Verify asm instance listed on your listening port.

    Summary of endpoints listening...

    (Check that the PORT and IP information is correct)

    Instance '+ ASM1' READY State, has 1 operation for this service...

    (3) in addition, connect to asm and check the connection

    Show u local_listener and entered into OEM parameter details are correct.

    (4) OEM, I think you add Cluster_ASM.

    Oracle_home_path--> you're grid House

  • I/o error: the network adapter could not establish the connection: connection to oracle database

    Hello

    I am not able to connect to the Oracle SQL developer database. I said / 0 error: the network adapter could not establish the connection.

    I started the listener, but what I see is, it points to a different IP address instead of the IP address of the host. How to change the name of host or IP address.

    I see that it points to the host name in listener.ora.

    Attached the screenshot

    Can someone help me solve this problem?

    Thanks in advance

    What he says is the listener.ora file is not necessary to start the listener.  If you rename, then start the receiver, then start the db, after a minute or two, the db should automatically register with the listener and then you can make a tnsping or otherwise connect to the database through the listener.

    I'm not entirely sure what's going on with your image, but I can't help but wonder if somehow something is not what you expect with the investigation period, whenever it starts.

    So use lsnrctl status lsnrctl services to see what the listener is the situation and tnsping and ping from the client to see what he thinks.

  • Windows 7 computer physical exported to the virtual machine and now will not boot on another machine

    Hello

    What I tried to do is the following:

    Export/create a virtual machine from the current physical running computer. After it's done, I plug in the USB key which contains the files of virtual computer for a laptop and try to start this virtual machine. It does not start due to "recent changes". This probably means that the OS never will start, right?

    This seems odd to me, or I can't understand what is happening here. I thought that to have a virtual machine means that the operating system could not doing the physical machine, it is running on, but just saw it is virtualized OS/machine.

    I would like to "clone" a current physical machine and then run it on another PC is because we need to have a client machine, convert applications on it and then return either the image (if they already had a running image) or we have a complete script on how to convert/upgrade for that client applications so that the downtime will be minimal and maximum success rate.

    Info:

    VMWare Workstation 7.1.2

    Windows 7 (desktop and laptop PC run this) 32-bit

    Some clients running ESX and we want to take a picture of that and do the same trick as for workstation

    I bought a copy of Virtualization Manager 2010 at the time where converter couldn't handle windows 7.

  • Unable to connect to MKS: virtual machine configuration file does not exist

    Guys,

    Need a little help I'm running the following

    vCenter Server 4.0.0 (build 208111)

    ESX Server 4.0.0 (build 208167)

    I have a computer virtual running WIndows 2000 Advanced and when I try and open the console I get a black screen and the error message following

    "" Unable to connect to MKS: virtual machine configuration file does not exist '. "

    I scoured the data store and all the files of the virtual machine appear to be in place, I thought deletin the virtual machine from the inventory and add the vmdk file, it would be a good idea?

    Thank you.

    Remove and add new inventory won't hurt (you could lose data historial for virtual machine), it probably won't solve the problem.

    I doubt, it is a problem with the .vmx file, but you can try:

    -Remove the VM of the inventory

    -To create the new virtual machine (with the same characteristics as the virtual machine that you removed), name it differently and do not add hard drives that it

    -Change the new VM settings and add the existing VMDK virtual machine that you deleted

    -Power on VM and try

    • You should always have your complete file to the virtual machine original intact, in case you need, you will always have your original vmx file to add it to the inventory.

    By doing these steps you re-create the vmx file.

    f this post was useful/solved your problem, please mark the points of wire and price as seem you. Thank you!
