Local by Flywheel: Disable Other Hypervisors Before Installing Local by Flywheel

Ian Grieve2 minute read0 comment

Local By FlywheelThis post is part of the series on Local by Flywheel.

Local by Flywheel works by installing VirtualBox; if you are running any other visrtualsiation software, you need to make sure that it, and the related hypervisor, is disabled.

In my case, I am using Hyper-V so will need to use bcdedit to stop the hypervisor via an elevated command prompt.

The command to use is:

Adminstrator: Command Prompt showing hypervisor successful disabled

bcdedit /set hypervisorlaunchtype off

Once the command has successfully completed, the machine will need to be rebooted; if a reboot is done performed, then the hypervisor will not be fully disabled and will cause problems.

Once you’ve finished installing and shutdown Local by Flywheel, you can restart the Hyper-V hypervisor using the following command (again a reboot will be required):

bcdedit /set hypervisorlaunchtype auto

Hyper-V Error Creating Virtual Machines

Ian Grieve3 minute read0 comment

Hyper-VA while ago I was having problems with Hyper-V whenever I tried to start a VM after my laptop had been to sleep or after it was first started up.

That problem went away recently after I upgraded to Windows 10 by rebuilding the laptop. However, it seems the problem has migrated to whenever I try to create a new virtual machine:

The server encountered an error while creatng

New Virtual Machine Wizard
The server encountered an error while creating {server name}.
The operation failed.
An unexpected error occurred: Logon failure: the user has not been granted the requested logon type at this computer. (0x80070569).
The operation failed.
The Hyper-V Virtual Machine Management server encountered an under unexpected error: Logon failure: the user has not been granted the requested logon type at this computer. (0x80070569).

This is a lot less disruptive than the originally problem as I started VMs a lot more often than I create them. And fortunately, the fix is the same as last time, so the batch file I created can still be used.

Run the batch file and the VM can be created; and even better is that I can keep the New Virtual Machine Wizard open with all of the settings configured when I run the batch file. So if I forget to run the batch file before starting to create the VM, I don’t lose any work.

Batch Command To Restart Hyper-V

Ian Grieve2 minute read5 Comments

Hyper-VI got a new laptop at work recently (i7 16GB RAM 1080P) and have finally been able to pretty much transition away from VMWare to Hyper-V (which I use at home for my test system); I only have a final couple of VMs to recreate or migrate. It has not all been smooth sailing however, as I have found that if the laptop goes to sleep or is switched off the VMs cannot be started again.

I think this is something to do the AD group policy rather than an inherent problem as my Surface Pro 3 works fine.

The solution is to restart the Hyper-V Virtual Machine Management service, but going into Services every time for this was soon going to get annoying, so instead I created a batch file I can run from a keyboard shortcut containing the following two lines:

net stop vmms
net start vmms

These commands stop and then start the service allowing me to use the VMs.

Error Starting Virtual Machine On Client Hyper-V

Ian Grieve3 minute read1 Comment

Hyper-VI make a lot of use of virtual machines for both testing and demonstrating Microsoft Dynamics GP. As a company, when I joined, Perfect Image tended to use VMware (I’ll reserve comment, which I realise tells it’s own story), but more recently have started making more use of Microsoft Hyper-V, which is what I also use at home for testing and writing my blog and books.

After installing Hyper-V on my work laptop I created a virtual machine and clicked start. Unfortunately, I received the below error messages:

Hyper-V Manager

I did some digging around and found that although Hyper-V was installed, the hypervisor wasn’t running. Fortunately, the laptop I have does support Hyper-V and I only had to do one thing which was to enable the hypervisor by opening an elevated command prompt and type the following command:

bcdedit /set hypervisorlaunchtype auto

Once I had run the command I was able to start the virtual machine without further problem; at least with Hyper-V.

What I found was that with the hypervisor running, I wasn’t able to start a VMware virtual machine. So a second command can be used to disable the hypervisor for those times when I need to use a VMware virtual machine:

bcdedit /set hypervisorlaunchtype off

Hopefully, I’ll be able to complete the transition away from VMWare very soon and stop toggling from one to the other.
