[Qemu-trivial] deleting vmbus driver from device manager

[Huzaifa Nazir]

Hi,

 I want to remove "Virtual machine bus" from my qemu VM. I followed following steps:

• Delete "c:\system32\vmbus.sys"
• Restart
• Uninstall "Virtual machine Bus" from Device manager. It was present as non-Plug and play drivers under hidden entries of Device Manager.
  
• Restart

I got succeeded but I am unable to save the snap shot afterwards. On "savevm " The error on Qemu prompt is "Device 'ide0-hd0' is writable but does not support snapshots".

Is it possible to remove vmBUS completely ? If yes please tell the correct way.

Regards,
