This article describes some of the most common error codes and messages you may encounter when you create or manage virtual machines VMs in Azure. You can leave comments on this page for feedback or through Azure feedback with azerrormessage tag. An error response always includes a status code and an error object. Each error object always contains an error code and a message.

If the VM is created with a template, the error object also contains a details section that contains an inner level of error codes and message. Normally, the most inner level of error message is the root failure. Alternatively, you can file an Azure support incident. Go to the Azure support site and select Get Support.

Please try reducing the VM size or number of VMs, retry later, or try deploying to a different Availability Set or different Azure location. The VM allocation failed due to an internal error.

Please retry later or try deploying to a different location. Please wait until the disk is completely detached and then try again. Addition of a VM with managed disks to non-managed Availability Set or addition of a VM with blob based disks to managed Availability Set is not supported.

Please create an Availability Set with 'managed' property set in order to add a VM with managed disks to it. Disk resizing is allowed only when creating a VM or when the VM is deallocated. This is not supported currently in Cross subscription Move. Please check the error details for the KeyVault resource Ids. You can examine the blob metadata for the disk reference information. Please update the secret version, add the required tags and retry. One or more errors occurred while preparing VM disks.

See disk instance view for details. Disk blobs can only be of type page blob. Please ensure it was created through the Storage Resource Provider in the same location as the compute resource.

Cannot attach an existing OS disk if the VM is created from a platform or user image. Container names must be characters in length and may contain only lower-case alphanumeric characters and hyphen. Hyphen must be preceded and followed by an alphanumeric character. This is presently not supported for disks.When writing code to develop a software application, the programmer needs to make sure that all known error messages are captured and displayed when a specific condition occurs.

A programmer needs to think about all the possibilities when dealing with a failure event. For example, writing a network communication code requires that the code starts with a ping routine and then continues to execute the other routines. In case of any error returned while executing the code, the programmer needs to return either a generic or known error message. A known error message is defined in the code and shown when a failure event occurs and the cause of the failure is "known.

Microsoft's Hyper-V Replica has been designed the same way. In the case of any failure event, a generic error message is shown if a known error message is not applicable. Sometimes, though, it can be difficult to troubleshoot the issues with Hyper-V Replica based solely on the generic error messages.

This tutorial will explain how to troubleshoot generic error messages and what you should do when a known error message occurs. Hyper-V Replica may generate the following generic and known error messages:. Known Error Message: Hyper-V prevented starting virtual machine because it is prepared for failover.

You might get hit with this error message, as shown in the below screenshot, when you are trying to start the Primary Virtual Machine. The error message says "Hyper-V prevented starting the virtual machine because it is prepared for failover. Please note that a virtual machine for which the "Planned Failover" has been initiated is turned off at the Primary Server and turned on at the Replica Server if you selected to do so.

Such virtual machines cannot be turned on at the Primary Server unless replication is broken or the reverse replication is initiated. This is expected behavior from Hyper-V Replica and can be safely ignored. You are trying to enable replication for a virtual machine and get hit with the generic error message as shown in the below screenshot.

the virtual machine is not in a valid state to perform the

Before we discuss the resolution of this error, let's understand what happens when you enable replication for a virtual machine.

When you enable replication or hit the "Finish" button in the wizard, the Primary Server creates a pointer for the virtual machine on the Replica Server. If it finds any virtual machine already configured with the same GUID, the above generic error message will be displayed. Note: A virtual machine with same GUID can exist on Replica Server only if replication was enabled previously for the virtual machine and then was later removed administratively.

In the current version of Hyper-V Replica, the Primary Server does not ignore if a virtual machine is already configured on the Replica Server. While Microsoft might update the Hyper-V Replica engine to include a mechanism that helps in fixing such issues, as of today it does not! Generic Error Message: Failed to perform the operation.

Hyper-V is not in a valid replication state to perform the operation. In the case of any maintenance activity at Primary Server, "Planned Failover" is initiated to bring the virtualized workloads at the Replica Server.

Reverse replication action is performed from the Replica Server in which the Primary Server performs the role of Replica Server and vice-versa. You could get hit with a generic error message if you execute the "Reverse Replication" action from the right-click context menu of the Replica Virtual Machine.

When you hit "Finish" in the "Reverse Replication Wizard," you could see this error message: "Failed to perform the operation. Hyper-V is not in a valid replication state to perform the operation," as shown in the below screenshot:. Since there are multiple reasons associated with the error message as to why it failed, a generic error message is shown.

To resolve the issue, consider the possibilities below:. This is a "Known" error message in the Hyper-V Replica code that indicates an issue with the name resolution.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

It only takes a minute to sign up. If I move the VM back to node 2 where the problem arose and the VM is running, I get an error during live migration and the VM fails back to node1 where it did run So it's like there is something wrong with Hyper-V on node 2 and not node 1.

Also node 3 has the same issue. Restarting the nodes is NOT an option since I will have this problem again at a later time AND because not all the VMs can run on node 1 which means my client company will experience downtime on the VMs not running on node 1. The virtual machine is not in a valid state to perform the operation.

When migrating a Virtual Machine which has a saved state, SCVMM uses built-in checks to determine whether a saved state VM can be migrated between hosts or deployed from a library to a host.

If these checks fail then we get the error message. Once you do this you should be able to migrate it from one host to another. Note: In VMM R2, you can set the Allow migration to a virtual machine host with a different processor property to allow a virtual machine to run on a host that has a different processor version than the host on which the virtual machine was created.

The virtual machine must be stopped to set this property. So you should use this only when necessary, such as to facilitate live migration between clustered hosts that have different processor versions. Last Updated: 18 Apr Was this information helpful?

Does this problem happen to only one VM or to all the VMs? Please try creating a new hard disk putting it at a different location by clicking the New button in the right pane of the Hyper-V Manager console, and then replacing the virtual hard disk of the problematic VM with this newly created virtual hard disk to see if the problem remains.

Best regards. The virtual machine is not in a valid state to perform the operation. This worked for me, and could perhaps for you too. I have Upgraded from 8. The error I get is this: at the top it says Virtual Machine Connection, then "The application encountered an error while attempting to change state of VM Name ",Screenshot below.

I have tried to create a new VM but I get the same error. I have tried giving "Everyone" permission of the directory I made, I deleted all the VMs Removed the Virtual Switch and stopped the service and removed the Hyper-V from windows features rebooted, made a different directory and reinstalled Hyper-V and rebooted and attempted to make a new VM and I get the same Error.

I have also remove the Anti-virus program just to make sure there wasn't something blocking. Here is a screenshot. I was having the little bit different problem. I was directly getting failed to start the virtual machine. In my scenario.

One portable hard disk was connected to the VM before my base Host machine was shutdown. For the precaution, We disconnected the portable hard disk from the Host base Machine during shutdown. After the Base Host Machine started properly.

We tried to start the VM guest. But got the error "Failed to start the VM". So we reconnected the portable hard disk and our VM started smoothly.

Cheers in advance. I love snapshotting. If you need instructions how to see summary information about any spicified VM using MOB, please contact our support team support veeam.

Thank you. If you edit the properties of the Veeam backup job, on the "Backup Destination" page click the "Advanced" button. On the "General" tab the second option should be labels "Backup Options" and should be called "Enable VMware tools quiescence". That's a little difficult to read, but actually simple to do, so hopefully I was clear enough with those instructions. Gareth, VIC snapshot does not leverage quiescence, so ability to snapshot in VIC does not mean anything yet concerning this issue I will try to find out from devs on what could be causing this error and post here.

I will not be surprised if I hear the most usual " give us all logs first, and then we will tell you ". Could this be pre-RTM or something?I'm trying to do backups of virtual machines that reside on an Hyper-V Windows not R2 cluster. The cluster contains of 2 nodes and has 3 CSV's. Backups are partially working, sometimes a VM is rebooted unexpectedly during the Hyper-V snapshot creation. This does not happen all the time, and it is not always the same VM.

In Commvault the backup fails at that moment with the message "Error creating virtual machine snapshot". In the Hyper-V event log or the event log of the VM that rebooted, I can not see any errors at the time the VM rebooted except for the unexpeced reboot message in the eventlog of the VM.

We are using Simpana 11 sp5 with the latest hotfixes. We also patched the Hyper-V nodes and VM's with the latest microsoft updates. Did anyone already encounter such an issue? Or does anyone have an idea about the issue? I'm not an Hyper-V specialist. I did check that the integration tools are installed and that the backup integration is active.
