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. You may also leave feedback directly on GitHub.Spb live concert 2019

Abstracted from the underlying server hardware, VMs are easy to protect and migrate from one server to another. Virtualization, however, does not guarantee flawless reliability.
Take a look at five of the most common causes of failed VM migrations and how to avoid these issues. To start a VM, you need available computing resources. Insufficient or over-committed resources may cause the VM to fail immediately.
Administrators usually see these types of resource problems on heavily consolidated servers or high availability clustersor when migrating VMs to other highly utilized servers without allowing adequate computing capacity for failover. A server upgrade would add resources, but performing workload balancing is a better solution. Redistributing one or more VMs between servers will free adequate resources to ensure successful VM startup. Virtualization abstracts workloads from the underlying hardware, but the hardware must still provide the critical features and functionality those workloads require.
Startup failures can occur when you migrate a VM to an older server that may lack hardware features the VM needs. Virtual machine migration best practices.Reverse scoring in r
Common VM monitoring and management errors. Using PowerShell to migrate virtual machines. In this case, you may need to manually restart the VM using command line options or migrate the VM to another physical server with similar CPU capabilities and restart the VM there.
You would then migrate the running VM to the desired server. Before you migrate or start a VM, verify that the destination server provides virtualization extensions, and be sure to enable those extensions in the BIOS.
IT personnel will need to adjust migration plans over time to ensure the use of compatible server hardware. Some virtualization-related tasks take a considerable amount of time to complete and continue to run in the background even after generating a timeout error.You can troubleshoot errors encountered while using Azure Backup with the information listed below:.
This could happen due to transient storage errors or insufficient storage account IOPS for backup service to transfer data to the vault within the timeout period. Configure VM backup using these best practices and retry the backup operation. The backup operation failed because the VM is in Failed state. To resolve this issue, follow these steps:. Restart VSS writers that are in a bad state.
From an elevated command prompt, run vssadmin list writers. The output contains all VSS writers and their state. For every VSS writer with a state that's not  Stableto restart VSS writer, run the following commands from an elevated command prompt:.
If you see permissions in the MachineKeys directory that are different than the defaults, follow these steps to correct permissions, delete the certificate, and trigger the backup:.
Fix permissions on the MachineKeys directory. By using Explorer security properties and advanced security settings in the directory, reset permissions back to the default values. Remove all user objects except the defaults from the directory and make sure the Everyone permission has special access as follows:. The Backup operation failed due to inconsistent state of Backup Extension. The snapshot operation failed as the snapshot limit has exceeded for some of the disks attached. Complete the below troubleshooting steps and then retry the operation.
Delete the disk blob-snapshots that are not required. Be cautious to not delete Disk blob, only snapshot blobs should be deleted. If Soft-delete is enabled on VM disk Storage-Accounts, configure soft-delete retention such that existing snapshots are less than the maximum allowed at any point of time.
Backup operation on the VM failed due to delay in network calls while performing the snapshot operation. To resolve this issue, perform Step 1. If the issue persists, try steps 2 and 3. This will ensure the snapshots are taken through host instead of Guest. Retry the backup operation. Step 3 : Try increasing the size of VM and retry the operation. If your backup takes more than 12 hours, or restore takes more than 6 hours, review best practicesand performance considerations.
But virtual machines that are migrated from on-premises datacenters won't have the VM Agent installed. Don't download the agent code from GitHub. If the latest agent isn't available for your distribution, contact the distribution support for instructions to acquire the latest agent.
VM backup relies on issuing snapshot commands to underlying storage.
Not having access to storage or delays in a snapshot task run can cause the backup job to fail. The following conditions can cause snapshot task failure:.
If snapshot delays cause backup failures, set following registry key:. If you used the remote desktop to shut down the virtual machine, verify that the VM status in the portal is correct. If more than four VMs share the same cloud service, spread the VMs across multiple backup policies. Stagger the backup times, so no more than four VM backups start at the same time. Try to separate the start times in the policies by at least an hour. If the virtual machine runs at high memory or CPU usage, more than 90 percent, your snapshot task is queued and delayed.
Eventually it times out. If this issue happens, try an on-demand backup.You try to power on a virtual machine, but the operation is unsuccessful and you receive an error message.
You cannot power on a virtual machine on an ESXi host. You might be unable to power on a virtual machine because of the following reasons.Linoria hub
The day evaluation period of the host is expired. The license of the host is expired. The edition of the license key does not match the configured features and resources on the host. The host on which the virtual machine runs is licensed with vSphere 5. The memory that is configured for the virtual machine that you try to power on will lead to exceeding GB of consumed vRAM. The evaluation period of the host is expired. Obtain a vSphere license key and assign the key to the ESXi host.
Verify that the edition of the license key matches the configured features and resources on the host. If they do not match, you cannot assign the license key. The memory that is configured for the virtual machine exceeds the amount of pooled vRAM for the host licenses. To free a certain amount of vRAM, reconfigure the memory for the powered on virtual machines on the hosts that are connected to vCenter Server.
Power off virtual machines to free a certain amount of vRAM. Reduce the amount of memory that is configured to the virtual machine that you try to power on. Power on a Virtual Machine Cause.An error occurred while attempting to start the selected virtual machine 'server' failed to change state. I shut down the VM before doing this and cannot remember if the VM actually came back up on the new Virtual Switch been a busy day.
I took another stab at this and got things running. I think the entire time, the problem was the Kaspersky antivirus solution running on that VM that had the issues, specifically, the Kaspersky Security Center 10 Network Agent service. Here's what I did to redo everything.
I did this for all 4 ports, so I knew which OS nics corresponded to physical nics. It's crazy how wrong the naming is in the OS by default.
Then, for all 4 physical nics, I traced the wires back to the switch to make sure port 1 on the server went to port 1 on the switch, Left all cables unplugged on the switch. At this point, I rebooted the physical server, for good measure.
Then I tested mailflow and it wasn't working At this point, I took a look at the services on the VM and saw that the Kaspersky Security Center 10 Network Agent service, which is a delayed start service, had not started. So I manually started it, tested mail flow, and BAM! Everything works. I rebooted the VM and this time that service came up fine on it's own. One of those two was the issue though. I had the same issue by stop-vm in powershell, a restart of the service in HyperV manager worked a treat and when it restarted the VM was running ready for login.
If you delete the saved state, that's like unexpectedly losing power. The VM will probably be okay afterwards. Try restarting the virtual machine management service.
Don't worry, it won't shut down your VMs, only restart the management service. This won't work if you have snapshots though. I just had the same error on a host restart and I remembered that I had previously installed a USB in passthrough mode and it was still looking for the drive and therefore failing.After you create a virtual machine, you can clone it to a template. Templates are master copies of virtual machines that let you create ready-for-use virtual machines.
You can make changes to the template, such as installing additional software in the guest operating system, while preserving the original virtual machine. You cannot modify templates after you create them. To alter an existing template, you must convert it to a virtual machine, make the required changes, and convert the virtual machine back to a template. To preserve the original state of a template, clone the template to a template. If a load generator is running in the virtual machine, stop it before you perform the clone operation.
Verify that you have the following privileges:. The template name determines the name of the files and folder on the disk.
For example, if you name the template win8tmp, the template files are named win8tmp. If you change the template name, the names of the files on the datastore do not change. Folders provide a way to store virtual machines and templates for different groups in an organization and you can set permissions on them.
If you prefer a flatter hierarchy, you can put all virtual machines and templates in a datacenter and organize them a different way.120v 208 240v transformer wire diagram diagram base website
Otherwise, you cannot proceed with the task. Otherwise, all the hard disks of the template will use the storage policy and datastore selected for the configuration files of the source virtual machine. If you select the Standard mode, all virtual disks are stored on a standard datastore. If you select the PMem mode, all virtual disks are stored on the host-local PMem datastore.
Configuration files cannot be stored on a PMem datastore and you must additionally select a regular datastore for the configuration files of the virtual machine. Non-PMem disks are affected by your choice of a VM storage policy and datastore or datastore cluster. For more information about persistent memory and PMem storage, see the vSphere Resource Management guide.Tw801 root
Same format as source uses the same disk format as the source virtual machine. The Thick Provision Lazy Zeroed format creates a virtual disk in a default thick format. Space required for the virtual disk is allocated when the virtual disk is created.
Data remaining on the physical device is not erased during creation, but is zeroed out later, on demand, on first write from the virtual machine. Thick Provision Eager Zeroed is a type of thick virtual disk that supports clustering features such as Fault tolerance.Changing virtual machine power states is useful when you do maintenance on the host. You can use the system default settings for the toolbar power controls or you can configure the controls to interact with the guest operating system.
For example, you can configure the stop button on the toolbar to power off the virtual machine or shut down the guest operating system. You can modify many virtual machine configurations while the virtual machine is running, but you might need to change the virtual machine power state for some configurations.
Virtual Machine Power Button Settings lists available power buttons and describes their behavior. Power Button. Shuts down the guest operating system or powers off the virtual machine. A power off operation displays a confirmation dialog box indicating that the guest operating system might not shut down properly.Translation dilation rotation reflection in a point line and plane
Use this power off option only when necessary. Suspends the virtual machine without running a script when VMware Tools is not installed.
When VMware Tools is installed and available, a suspend action runs a script, and suspends the virtual machine. Powers on a virtual machine when a virtual machine is stopped, or resumes the virtual machine and runs a script when it is suspended and VMware Tools is installed and available.
Resumes the virtual machine and does not run a script when VMware Tools is not installed. Resets the virtual machine when VMware Tools is not installed.
Restarts the guest operating system when VMware Tools is installed and available. A reset operation displays a confirmation dialog box indicating that the guest operating system is not shut down properly.
Verify that the vSphere Client is logged in to a vCenter Server. Verify that you have access to at least one virtual machine in the inventory. Verify that you have privileges to perform the intended power operation on the virtual machine.

To set optional power functions, you must install VMWare Tools in the virtual machine. Power off the virtual machine before editing the VMware Tools options.
In the vSphere Client inventory, right-click the virtual machine and select Edit Settings. Click the Options tab and select VMware Tools.
Event ID - 19050
In the right panel, select the Power Controls for the virtual machine. Shut Down Guest. Uses VMware Tools to initiate an orderly system shut down of the virtual machine. This type of powering off is known as a "soft" power operation.
Soft power operations are possible only if the tools are installed in the guest operating system. Power Off. Immediately stops the virtual machine. This type of powering off is known as a "hard" power operation. System Default. Follows system settings. The current value of the system settings is shown in parentheses. Pauses all virtual machine activity.
The current value of the system setting is shown in parentheses.
