VM Status showing "Unknown"

Question

I have 2 VMs, they are on auto shutdown mode, but now their status is showing "Unknown", which means neither they are starting up , nor we are able to connect.

We performed various steps like trying to redeploy it, but it failed or trying to reset NIC, it failed too ( which is not possible until VM is ON )

Could anyone please provide any helpful solution which we can try? Will be grateful to you all, thanks!!

I also read on Microsoft form, that this issue happens during deallocation and its somewhat bug, and only way to fix it is to open support request on Azure?

Please help!

By the way, when we try to start VM, it gives this error after 30 minutes...

The VM allocation failed due to an internal error. Please retry later or try deploying to a different location. (Code: AllocationFailed)

Here are some suggestions to try: https://techcommunity.microsoft.com/t5/azure-compute/azure-vms-stuck-at-status-unknown-or-updating-solution/m-p/3821385

If this does not work out, contact support.

Another option (not ideal, but it might work if you need access to the VM right away) is to create a snapshot of the disks and build a new VM using these disks

Answer 2

Hi @Michael T,

Thanks for contacting Microsoft Q&A platform.

The error message indicates that there was a problem with allocating resources for the virtual machine deployment. This error can occur due to various reasons, including temporary issues with Azure infrastructure or resource constraints in the selected region.
Following below steps will help you to troubleshoot.

• As suggested in the error message, try retrying the deployment later. Sometimes, the issue may be temporary, and retrying the deployment after some time may succeed.
• If retrying the deployment in the same location continues to fail, consider deploying the virtual machine to a different Azure region. Choose a region where resource allocation may be more available and less congested.
• Verify that you have sufficient resource quotas in the selected Azure region to deploy the virtual machine. Resource quotas may limit the number of virtual machines or other resources you can deploy in a specific region.
• If the issue persists and you're unable to deploy the virtual machine, consider reaching out to Azure support for further assistance. Azure support can investigate the issue and provide guidance on resolving the allocation failure.

Hope this helps you.
