VM can't be opened from MS HyperV manager, any thing wrong with the VM?

This is using MS Windows Server 2008r2. We are using the MS HyperV for only 1 vm. However, recently we wanted to open vm but found that this can not be opened. 


What went wrong and how to solve it?

Restart the VM.  Can you connect then?

in hyper-v manager what is the status of the virtual machine?
Can you access the .vhd i.e. if you double click on it does it load into windows and is it visible in disk managmement?

Hi Lee W,

I have to approval to restart the vm. This should be the last resort method.

I've seen this problem myself YEARS ago... (You should NOT be using Hyper-V 2008/2008R2 - it's VERY old and a security risk).

The easiest solution is to reboot the VM.  I don't know if there's another solution - I didn't waste my time trying to find one considering that reboots of computers fix problems as often as they do.  What's the first thing you tell the user? Did you reboot?

Hi Lee W,

We have another MS Windows server 2016 with plenty of disk space. My colleague up the MS hyperV on this 2016 server, and then copy the vhd over to create a new Vm. This VM can be booting up and open.

So, looks like the problem is on the existing hyperV infra on the original w2k8r2 server. What could be the problem?
