Error while powering on unable to open kernel device vmcidev vmx

Error while powering on unable to open kernel device vmcidev vmx

for the past few months i have been trying to figure out a solution for this problem and i really hav high hopes in this thread!

Here’s the problem:-

Every time i try powering on my virtual machine it says

» Unable to open kernel device «\.VMCIDevVMX»: Overlapped I/O operation is in progress. Did you reboot after installing VMware Player?

I have tried to to edit the .vmx file and replace the TRUE with FALSE next to vmci0.present and i have also tried deleting the file

PLEASE i need help really badly. Specially from the experts.

And if u think that my system doesn’t support hardware virtualisation, then that’s not the case because i hav previously installed the virtual machine before but i had to remove it for a few reasons! :'(

i also have another problem. i’ve installed vmware workstation on my external hard drive, so whenever i try to re-install or repair or uninstall my software it can’t. it says that the «MSI» failed to install.

I found the vmx but its a file that get me to another file. and that file does not have true or false

it goes like this:

docs then VMs then Debian 10.x 64-bit then Debian 10.x 64-bit.vmx.lck then M04698

Also had this problem after incorporating VMWare Workstation into a captured wim for SCCM deployment.

to C:ProgramDataVMwareVMware Workstationsettings.ini

fixes it for me on all newly created VMs after deploying the image to PC’s.

OMG . Thank you so much. Setting vmci0.present = «false» is what solved my problem.

Running vmware workstation 16 pro in Windows 10 as host and Fedora 35 in the VM and around 3 weeks ago, after performing a windows update, multiple applications started having network connection issues, including vmware workstation and ALL of my VMs. But the fedora VM is the most important.

The fix was finally re-creating the VMnet0 bridge and the vmci0.present setting change to false. I’ve been racking my head for weeks trying to get this to work without having to reinstall windows. I know the underlying Windows update problem is still there and since I did not have a recent backup, would probably need re-install windows but so so so glad I got the fedora VM working again for now. Will worry about the rest of Windows later.

выдает ошибку iPXE — Nothing to boot. No such file or directory http://ipxe.org/err/2d03e1

Зашел в командную строку iPXE и выполнил все как здесь написано — переменные $ и $ пустые. Подскажите из-за чего эта ошибка и как ее решить.

Всем доброго времени суток.
Возникла следующая проблема:
На компе установлена Win 8.1. Решил установить виртуальную ось: Win XP.
Попробовал использовать две программы: VirtualBox, VMware Workstation.
Вопросы:
1. установил VirtualBox, создал и настроил гостевую ось. Удалось даже установить и запустить ее. Проблема в том, что не работает кнопка хост. Нет никакой возможности перейти в основную систему. Установил VBoxGuestAdditions. После этого вообще пропал курсор мышки. В чем может быть проблема и как ее решить? поиск в тырнете совершенно не дал результатов(
2. установил VMware Workstation. Установил гостевую систему, настроил, но звук работает крайне плохо: прерывистый и «слишком низкий».

Всем спасибо за ответы.

А какую кнопку нажимали ? у меня, например, virt.box сразу сказал, что я тут посмотрел — всё ок, можешь ничего не нажимать и просто, когда мышка в фокусе окна — всё ок. Когда утащил за пределы окна — ты в основной системе.
Если что — кнопка выхода из виртуалки — правый контрол для винды.
а в диспетчере устройств-то мышка видна ?
посмотреть можно нажав кнопку windows добраться стрелочками до мой компьютер, нажать кнопку «контекстное меню» обычно внизу клавиатуры справа есть такая и выбрать управление компьютером.

Еще можно виртуальную мышку, для лиц с ограниченными возможностями, но тут это скорее не нужно.
В на форуме пишут, что вроде бы помогает удаление VBoxGuestAdditions. У тебя проблема с мышкой, когда винда в оконном или в полноэкранном режиме ? попробуй в оконном нажать правый контрол и пару раз кликнуть правой кнопкой в виртуалкой.

Но для win использовать hyper-v, в целом, правильно )

While the error may seem complicated, this VMware Workstation error is actually very easy to fix.

Virtual machine software called VMware Workstation runs various operating systems on a single host computer. Every virtual machine in VMware can run a single instance of any operating system like Microsoft, Linux, etc, at the same time. However, it is not free from errors. When launching VMWare Workstation, we may see an Unable to open kernel device ‘\.VMCIDevVMX’ error due to misconfigured VMX file or corrupted VMware Workstation program. In this article, we will discuss the matter in detail and find solutions to resolve the said error.

Unable to open kernel device ‘\. VMCIDevVMX’: The operation completed successfully. Did you reboot after installing VMware Workstation?
Module ‘DevicePowerOn’ power on failed.
Failed to start the virtual machine.

To fix Failed to start the virtual machine., Module DevicePowerOn power on failed, Unable to open kernel device \.vmcidevvmx error you may execute the following solutions:

1. Restart your computer
2. Edit VMX File
3. Repair VMware Workstation
4. Uninstall VMware Workstation

Let’s get started.

1] Restart your computer

If you have read the error message, one thing is clear; it is asking you to restart the computer. This usually happens when you install VMware for the first time, as there are some adjustments that need to make by the computer once the installation process is over or after creating a new VM.

Regardless, before going to the major troubleshooting solutions, restart your computer and then open the VMWare Workstation. Hopefully, Windows will make the required changes and resolve the issue.

2] Edit VMX File

In a VMware workstation, the vmx file is a configuration file that is created by VMware workstation software. It keeps virtual machine settings in plain text such as the virtual machine’s memory, hard disk, and processor limit settings. To resolve this issue, we should make some changes in the vmx file.

Let’s start to modify the vmx file.

• Locate the folder where VMware has been installed.
• Now search the VMX file of the Virtual machine in that folder. It may or may not end with VMX, so, look for a file with three white pages as its icon.
• Right-click on the virtual machine vmx file and select open with Notepad.
• Search for the line with vmci0.present.
• Change the value from “TRUE” to “FALSE”.
• Save the notepad file and close the file.
• Finally, Restart the computer.

Hopefully, after modifying the vmx file, the said error will be resolved.

3] Repair VMware Workstation

You may encounter the said error if VMware Workstation is corrupted. We can pretty easily repair the file by reinstalling the app itself, however, it is an extreme solution as it is quite long, that is VMWare Workstation has a feature to repair the program. To repair VMware Workstation, follow the prescribed steps to do the same.

• Open Settings by Win + I.
• Go to Apps > Installed apps or Apps & Features.
• Search for VMware Workstation.
  
  • Windows 11: Click on the three vertical dots and click on Modify/Change.
  • Windows 10: Select the app and then click on Modify/Change.
• Follow the on-screen instructions to repair the VMWare Workstation.

Once the program is repaired, don’t just launch it; first reboot your computer and then launch the VMware Workstation.

4] Uninstall VMware Workstation

As we mentioned earlier, if we get this error, there is a high chance that our VMware program is corrupted. You can run the repair utility present inside the program and if that doesn’t work, your last resort is to reinstall it. So, go ahead and uninstall VMware Workstation using the following steps.

• Open Settings by Win + I.
• Go to Apps > Installed apps or Apps & Features.
• Search for VMware Workstation.
  
  • Windows 11: Click on the three vertical dots and click on Uninstall.
  • Windows 10: Select the app and then click on Uninstall.
• Click on the Uninstall button to confirm your actions.

After uninstalling the app, go to kb.vmware.com, download the installation package and install it. Hopefully, this will do the trick for you.

Hopefully, you will be able to resolve the issue using the solutions mentioned in this article.

Why is my Virtual Machine not opening?

Our Virtual Machine may fail to work if you have allocated less memory than what is required by the VM. This statement goes for both Primary Memory, which is your RAM, and Secondary Memory, which is your Hard Drive. So, when creating a VM, allocate more space it to it, or if you have already created go to its settings and make the required adjustments.
