Solved: Monitor ModuleLoop power failure

First of all, if you encounter this message on your screen, don’t worry, you have landed at the right place. Take a look.

Next, the details of this message are mentioned here:

Power On VM
Key                haTask-2-vim.VirtualMachine.powerOn-164454246
Description        Power On this virtual machine
Virtual machine
State              Failed - Module 'MonitorLoop' power on failed.
Errors
   Module 'MonitorLoop' power on failed.
   File system specific implementation of Lookup[file] failed
   File system specific implementation of LookupAndOpen[file] failed
   Failed to extend swap file from 0 KB to 67108864 KB.
   Current swap file size is 0 KB.
   Failed to extend the virtual machine swap file
   Could not power on virtual machine: No space left on device.
   Failed to power on VM.
    Failed to start the virtual machine.

Now, why does this happen? What is the prominent reason due to which such a failure occurs? Let us analyze.

Reason

Technically, the source Virtual Machine’s configuration is utilized by VM replication. The purpose is to replicate it completely like the target host. 

Now, this issue occurs when sometimes there are scarce resources with the destination host in comparison to the Source Virtual Machine. 

You may wonder, what kind of resources! For instance, memory, storage, or the number of cores. 

Another prominent reason related to the failure is the availability of less storage space in the Virtual machine. Meaning, when you want to use the MonitorLoop module, there should be enough space on your device to access it.

For more clarity, here is an example. 

Suppose, the source virtual machine imbibes more cores as compared to your destination host. Now, this factor surely creates an issue and leads to failure. 

Moving on, how can you fix the error and continue working on the VM?

Solution

On witnessing the error message, head on to the vSphere client. It tells you about that particular resource that is responsible for the VM failure. Once you follow this step, your screen displays the following window. Have a look.

The next target is to make specific changes in the VM. Try to power on your system manually. This step assists you to temporarily utilize the replicated VM. 

Final words

This was a quick and step-by-step guide for you to tackle such a failure. We hope that this article assists you in the best way possible.

Computers has always fascinated me since I was a kid and here we are. I love travelling for 2 reasons: the first one to see a new part of the world and second (the most important one) to experience the rich culture hidden among the country and people. I'm pretty good at cooking but very poor when it comes to baking.
