Unable to migrate VM

Hello,

I converted a desktop to a VM to work on VMware Workstation using VMware Converter.

After I migrate this VM from VMware Workstation to ESXi 6.7.

Now I have 2 issues :

  • First I cannot migrate this VM. I have this error : "Virtual machine is configured to use a device that prevents the operation: Device 'HD audio ' has a backing type that is not supported. "This is a general limitation of the virtual machine's compatibility with the ESXi version of the selected host."
  • Then the sound doesn't work on this VM

How can I solve this issue?

Thanks for your help.

Regards,

ESXi does not support sound controllers. You must remove this device from the VM's configuration.

It is technically possible but unsupported and can lead to instabilities. You will have to manually remove those lines from the VMX file and then reload the virtual machine.

> Device 'HD audio ' has a backing type that is not supported.

This does not mean that ESXi does not support virtual audio devices.

It means that the audio device specified in the vmx-file of your VM is invalid for an ESXi-host.

To clean up remove all parameters that start with sound.*

from the vmx-file and only keep

sound.present = "true"

Then ESXi will try to assign a soundcard for that VM on next boot  - if your host supports that.

Do you need support with a recovery problem ? - call me via skype "sanbarrow"
