Windows 10: Hyper V Manager unable to create new virtual machine

Hyper V Manager is unable to create new virtual machine. When I went and checked the event viewer I found this error message The Hyper-V Virtual Machine Management service encountered an unexpected error: %%2147778704 0x80048090.

:)

 

Where is the Hyper V Manager, How to I start it ?

I am trying to setup an XP virtual Machine on Windows 10 Pro.

I followed the steps in Neil Peterson article of 5/9/2016.

System Requirements - done - ok

Install Hyper-V - done - ok

Create a Virtual Switch - skip

Create a Virtual Machine

Create a Virtual Machine with Hyper-V Manager

These steps walk through how to manually create a virtual machine and deploy an operating system to this virtual machine.

• 
  In Hyper-V Manager, click Action > New >
  Virtual Machine to bring up the New
  

Uhhhhhhhhh - this step obviously implies one knows

1) Where the Hyper-V Manager is

2) How to start the Hyper-V Manager

Isn't that odd ?

 

Hyper-V Virtual Machine not recognised

Ok that's why you can't add it... Virtual Machines are stored in a .vhd or .vhdx file. The xml file is used for the VMs but you also have to have a valid vhd

Are you trying to import one you used previously or just trying to create a new VM?

 

Windows 10 x64 v1809 - Hyper-V Virtual Switch Manager Unable to Create Default Switch

After upgrading to v1809 from v1803, I turned Hyper-V feature Off then On.

Since the upgrade, the Default Switch no longer exists and the Virtual Switch Manager is unable to crate it automatically as it would normally. I can see the Default Switch appear for a few seconds in the Network Adapters, then its gone. This happens
several time whenever I launch the Virtual Switch Manager.

I can create other virtual switches.

Once the Virtual Switch Manager lists the Default Switch with a Load Failed message.

I have used netcfg -d command to delete all adapters and Turned Hyper-V feature Off/On several times with no success.

Suggestions welcome. Thanks
