Some mitigations will be enabled by default. The following section describes the features which are off by default and/or reliant on hardware support (microcode). Enabling these features may cause a performance impact. Reference your operating system provider's documentation for further instructions\nStep 1: Disable hyper-threading on the VM - Customers running untrusted code on a hyper-threaded VM will need to disable hyper-threading or move to a non-hyper-threaded VM. Reference [this doc](https://learn.microsoft.com/en-us/azure/virtual-machines/</en-us/azure/virtual-machines/acu>) for a list of hyper-threaded VM sizes (where ratio of vCPU to Core is 2:1). To check if you're running a hyper-threaded VM, run the `lscpu` command in the Linux VM.\nIf `Thread(s) per core = 2`, then hyper-threading has been enabled.\nIf `Thread(s) per core = 1`, then hyper-threading has been disabled.\nSample output for a VM with hyper-threading enabled:\nConsole Copy\n```\nCPU Architecture: x86_64\nCPU op-mode(s): 32-bit, 64-bit\nByte Order: Little Endian\nCPU(s): 8\nOn-line CPU(s) list: 0-7\nThread(s) per core: 2\nCore(s) per socket: 4\nSocket(s): 1\nNUMA node(s): 1\n\n```\n\nIf you're running a hyper-threaded VM, [contact Azure Support](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/aka.ms/MicrocodeEnablementRequest-SupportTechnical>) to get hyper-threading disabled. Once hyper-threading is disabled, support will require a full VM reboot. Refer to [Core count](https://learn.microsoft.com/en-us/azure/virtual-machines/<#core-count>) to understand why your VM core count decreased.\nStep 2: To mitigate against any of the below CPU based memory vulnerabilities, refer to your operating system provider's documentation:\n * [Redhat](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/access.redhat.com/security/vulnerabilities>)\n * [SUSE](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/www.suse.com/support/kb/?doctype%5B%5D=DT_SUSESDB_PSDB_1_1&startIndex=1&maxIndex=0>)\n * [Ubuntu](https://learn.microsoft.com/en-us/azure/virtual-machines/<https:/wiki.ubuntu.com/SecurityTeam/KnowledgeBase/>)\n\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#core-count>)" } ]

When hyper-threading is disabled, Azure removes a thread and surfaces up single threaded cores (physical cores). The ratio of vCPU to CPU is 2:1, so once hyper-threading is disabled, the CPU count in the VM will appear to have decreased by half. For example, a D8_v3 VM is a hyper-threaded VM running on 8 vCPUs (2 threads per core x 4 cores). When hyper-threading is disabled, CPUs will drop to 4 physical cores with 1 thread per core.\n[](https://learn.microsoft.com/en-us/azure/virtual-machines/<#next-steps>)" } ]

These are based on actions performed by Service Fabric on your nodes and your cluster or management decisions made by a cluster owner/operator. These events can be accessed by configuring in various ways including configuring [Azure Monitor logs with your cluster](https://learn.microsoft.com/en-us/azure/service-fabric/<service-fabric-diagnostics-oms-setup>), or querying the [EventStore](https://learn.microsoft.com/en-us/azure/service-fabric/<service-fabric-diagnostics-eventstore>). On Windows machines, these events are fed into the EventLog - so you can see Service Fabric Events in Event Viewer.\nHere are some characteristics of these events\n * Each event is tied to a specific entity in the cluster, for example, Application, Service, Node, Replica.\n * Each event contains a set of common fields: EventInstanceId, EventName, and Category.\n * Each event contains fields that tie the event back to the entity it's associated with. For instance, the ApplicationCreated event would have fields that identify the name of the application created.\n * Events are structured in such a way that they can be consumed in various tools to do further analysis. Additionally, relevant details for an event are defined as separate properties as opposed to a long String.\n * Events are written by different subsystems in Service Fabric are identified by Source(Task) below. More information is available on these subsystems in [Service Fabric Architecture](https://learn.microsoft.com/en-us/azure/service-fabric/<service-fabric-architecture>) and [Service Fabric Technical Overview](https://learn.microsoft.com/en-us/azure/service-fabric/<service-fabric-technical-overview>).\n\nHere's a list of these Service Fabric events organized by entity.\n[](https://learn.microsoft.com/en-us/azure/service-fabric/<#cluster-events>)" } ]

Configured extensions and custom data scripts are run, while persisted data disks are retained.\n * [Extension sequencing](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<virtual-machine-scale-sets-extension-sequencing>) is supported.\n * Can be enabled on a scale set of any size.\n\nNote\nBefore enabling automatic OS image upgrades, check [requirements section](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<#requirements-for-configuring-automatic-os-image-upgrade>) of this documentation.\n[](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<#how-does-automatic-os-image-upgrade-work>)" } ]

The image upgrade is then applied to an individual scale set in a batched manner as follows:\n 1. Before you begin the upgrade process, the orchestrator ensures that no more than 20% of instances in the entire scale set are unhealthy (for any reason).\n 2. The upgrade orchestrator identifies the batch of virtual machines to upgrade, with any one batch having a maximum of 20% of the total instance count, subject to a minimum batch size of one virtual machine. There is no minimum scale set size requirement and scale sets with 5 or fewer instances have 1 virtual machine per upgrade batch (minimum batch size).\n 3. The OS disk of every virtual machine in the selected upgrade batch is replaced with a new OS disk created from the image. All specified extensions and configurations in the scale set model are applied to the upgraded instance.\n 4. For scale sets with configured application health probes or Application Health extension, the upgrade waits up to 5 minutes for the instance to become healthy, before moving on to upgrade the next batch. If an instance does not recover its health in 5 minutes after an upgrade, then by default the previous OS disk for the instance is restored.\n 5. The upgrade orchestrator also tracks the percentage of instances that become unhealthy post an upgrade. The upgrade stops if more than 20% of upgraded instances become unhealthy during the upgrade process.\n 6. The above process continues until all instances in the scale set have been upgraded.\n\nThe scale set OS upgrade orchestrator checks for the overall scale set health before upgrading every batch. While you're upgrading a batch, there could be other concurrent planned or unplanned maintenance activities that could impact the health of your scale set instances. In such cases if more than 20% of the scale set's instances become unhealthy, then the scale set upgrade stops at the end of current batch.\nTo modify the default settings associated with Rolling Upgrades, review Azure's [Rolling Upgrade Policy](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/</en-us/rest/api/compute/virtual-machine-scale-sets/create-or-update?tabs=HTTP#rollingupgradepolicy>).\nNote\nAutomatic OS upgrade does not upgrade the reference image Sku on the scale set. To change the Sku (such as Ubuntu 18.04-LTS to 20.04-LTS), you must update the [scale set model](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<virtual-machine-scale-sets-upgrade-scale-set#the-scale-set-model>) directly with the desired image Sku. Image publisher and offer can't be changed for an existing scale set.\n[](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<#os-image-upgrade-versus-reimage>)" } ]

When you perform an OS image upgrade, Azure creates new virtual machines with the updated OS image and gradually replace the old virtual machines in the scale set with the new ones. This process is typically performed in stages to ensure high availability. OS image upgrades are a non-disruptive way to apply updates or changes to the underlying OS of the virtual machines in a scale set. Existing virtual machines are not affected until they are replaced with the new instances.\nReimaging a virtual machine in a scale set is a more immediate and disruptive action. When you choose to reimage a virtual machine , Azure stops the selected virtual machine, perform the reimage operation, and then restart the virtual machine using the same OS image. This effectively reinstalls the OS on that specific virtual machine. Reimaging is typically used when you need to troubleshoot or reset a specific virtual machine due to issues with that instance.\nKey differences:\n * OS Image Upgrade is a gradual and non-disruptive process that updates the OS image for the entire Virtual Machine Scale Set over time, ensuring minimal impact on running workloads.\n * Reimage is a more immediate and disruptive action that affects only the selected virtual machine, stopping it temporarily and reinstalling the OS.\n\nWhen to use each method:\n * Use OS Image Upgrade when you want to update the OS image for the entire scale set while maintaining high availability.\n * Use Reimage when you need to troubleshoot or reset a specific virtual machine within the virtual Machine Scale Set.\n\nIt's essential to carefully plan and choose the appropriate method based on your specific requirements to minimize any disruption to your applications and services running in a Virtual Machine Scale Set.\n[](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<#supported-os-images>)" } ]

Application Health Probes are not supported for Service Fabric scale sets. Non-Service Fabric scale sets require either Load Balancer application health probes or [Application Health extension](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<virtual-machine-scale-sets-health-extension>).\nIf the scale set is configured to use multiple placement groups, probes using a [Standard Load Balancer](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/</en-us/azure/load-balancer/load-balancer-overview>) need to be used.\nNote\nOnly one source of health monitoring can be used for a Virtual Machine Scale Set, either an Application Health Extension or a Health Probe. If you have both options enabled, you need to remove one before using orchestration services like Instance Repairs or Automatic OS Upgrades.\n[](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<#configuring-a-custom-load-balancer-probe-as-application-health-probe-on-a-scale-set>)" } ]

The same endpoint for an existing HTTP probe or TCP probe can be used, but a health probe could require different behavior from a traditional load-balancer probe. For example, a traditional load balancer probe could return unhealthy if the load on the instance is too high, but that would not be appropriate for determining the instance health during an automatic OS upgrade. Configure the probe to have a high probing rate of less than two minutes.\nThe load-balancer probe can be referenced in the _networkProfile_ of the scale set and can be associated with either an internal or public facing load-balancer as follows:\nJSON Copy\n```\n\"networkProfile\": {\n \"healthProbe\" : {\n \"id\": \"[concat(variables('lbId'), '/probes/', variables('sshProbeName'))]\"\n },\n \"networkInterfaceConfigurations\":\n ...\n}\n\n```\n\nNote\nWhen using Automatic OS Upgrades with Service Fabric, the new OS image is rolled out Update Domain by Update Domain to maintain high availability of the services running in Service Fabric. To utilize Automatic OS Upgrades in Service Fabric your cluster node type must be configured to use the Silver Durability Tier or higher. For Bronze Durability tier, automatic OS image upgrade is only supported for Stateless node types. For more information on the durability characteristics of Service Fabric clusters, see [this documentation](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<../service-fabric/service-fabric-cluster-capacity#durability-characteristics-of-the-cluster>).\n[](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<#using-application-health-extension-1>)" } ]

You can configure the extension to probe on an application endpoint and update the status of the application on that instance.

These custom metrics can be used to tell the scale set the order in which virtual machines should be updated when a rolling upgrade is triggered. The custom metrics can also inform your scale set when an upgrade should be skipped on a specific instance. This allows you to have more control over the ordering and the update process itself.\nCustom metrics can be used in combination with other rolling upgrade functionality such as [automatic OS upgrades](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<virtual-machine-scale-sets-automatic-upgrade>), [automatic extension upgrades](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<../virtual-machines/automatic-extension-upgrade>) and [MaxSurge rolling upgrades](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<virtual-machine-scale-sets-maxsurge>).\nFor more information, see [custom metrics for rolling upgrades on Virtual Machine Scale Sets](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<virtual-machine-scale-sets-rolling-upgrade-custom-metrics>)\n[](https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/<#get-the-history-of-automatic-os-image-upgrades>)" } ]
