  1. Effective route tables for VMSS

    As confirmed by PG in Support case 119091125000146 there is no way to query the effective route table for a VMSS instance, thus leaving 100% VMSS based infrastructures completely blind.

  2. Allow VM console access when storage account has firewall enabled

    It's pretty ridiculous that the Azure VM serial console won't work when the boot diagnostics storage account has a firewall enabled.

    First, it should be possible to use a firewall for additional protection of boot diagnostics. I understand that the storage has to be written from the host server, not the VM, so it might not be on the correct vnet; but this should be considered a "trusted Azure service", or there should be another option to allow it.

    Second, the Serial Console is not the same as boot logging. They are two separate things! I should be able to…

  3. Ubuntu 20.04LTS VMSS Automatic OS Upgrade Support

    As of today, Ubuntu Server 20.04LTS is not supported by VMSS Automatic OS Upgrade feature (https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-automatic-upgrade#supported-os-images).
    This one has been released on April 23, 2020.
    Can you please kindly consider support it with VMSS Automatic OS Upgrade feature?

    Many thanks,

  5. Prevent the 'failed' state when VMSS autoscaled to subnet namespace size

    VMSS easily turn 'failed' status with following step and cannot recover without delete and re-create the VMSS.

    Repro step is:
    1. Create Vnet and subnets. The address space of subnet for VMSS is /27 (for example)
    2. Create AppGW(Small/1instance, no publicIP) in Vnet
    3. Create VMSS under AppGW
    ... set the Autoscale rule as Min/Max/default : 2/25/2
    ... In my case, I created StandardDS1v2 size VMSS
    4. change Autoscale parameter to 16/25/16
    5. change Autoscale parameter to 25/25/25
    =>reproduces

    want to prevent the state. thanks,

  6. vmss

    When adding a Inbound NAT Rule to a load balancer, I get the following error: "Full virtual machine scale set support for the portal is coming soon. Adding or editing references between load balancers and scale set virtual machines is currently disabled for load balancers that contain an existing association with a scale set."

    How soon is "coming soon"? I've seen this error for about 6 months now.

  7. query VMSS instance properties in Azure Resource Graph Explorer

    Please expose the individual VMSS instance properties in Azure Resource Graph Explorer. I can generate reports with name, private IP, and so on for the virtualmachines resource type but for VMSS I am only able to see the VMSS resource itself, no instance properties.

    Azure Resource Graph Explorer is far superior to PowerShell/CLI for building reports quickly on resources across subscriptions, regions, etc.

  8. Allow update of gallery image for VMSS

    When referencing a custom image in a VMSS from a Shared Image Gallery (Preview), it cannot be updated to refer to a new image. This results in an error code "PropertyChangeNotAllowed".

    Today, a VMSS can be updated to a new image reference when it references a managed image that does not reside in a Shared Image Gallery.

  9. VMSS rolling updates on custom images

    Allow rolling updates on custom images.

    Currently if you build a custom image and create a VMSS with it you have to manually "roll it out" via upgrade. Seems silly when the image is housed and built just like any other. were just talking about watching the upgrade process by way of the VM's "upgrade status"

    seems doable not sure why its held back, especially when the VMSS set knows its "not current"

  10. request new feature: alerts for extensions/agents in VMSS

    One of my customer want to proactively monitor the status of Guest Agent and Extensions on VM within VMSS. For example, we may set alert when heartbeat is lost or the extension status go to failed.

  11. Add 2016-DataCenter-Server-Core available for Virtual Machine Scale Set Deployments from Portal

    The Microsoft managed list of available images for scale sets currently does not include Windows Server 2016 Core. Providing our own image works but is painful as we must maintain the image.

    Since Windows Server Core images are already managed by Microsoft for IAAS VMs, you should also offer this images for scale sets.

  12. Automatic instance repair for instances in Stopped status state

    This option will be extremely useful for scenarios where the instance has been turned off from within the operating system and is in the Stopped state (not Stopped (deallocated)).
    We came across a scenario where a script, which runs inside VMs, was turning off instances in the wrong way.

  13. Allow Termination Events to be enabled on VMSS with Low-Priority/Spot

    Would like the ability to enable Termination events on Low-Priority/Spot VMSS.

    Low-Priority/Spot VMs currently have the ability to react to pre-emption events, but lack the ability to handle scale-in events like the regular priority, auto-scaling, Scale Sets do.

    I'm acknowledging that this appears to be an intentional decision (see examples below), but think that this would be useful.

    Terminate Notification:
    https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-terminate-notification#tips-and-best-practices

    As well as the api response when attempting to enable it via PoSH:

    "Virtual Machine Scale Sets with extension scheduledEventsProfile must have property priority set to Regular"

  14. Add ephemeral OS disk support for Spot instance Virtual Machine Scale Sets (vmss)

    In the past you could create low priority vm scale sets with an ephemeral os disk. This feature was dropped when spot instances were introduced. Please add ephemeral os disk support for spot instance vm scale sets.

  15. Get public IPs from metadata for VM Scale Sets instances

    Case with the Support shows a limitation in the metadata for VMSS instances.

    Indeed, it is actually not possible to get the Public IP of a publicly addressed VM Scale Set instance from the metadata.

    I hope this limitation will be shortly fixed.

  16. Request new feature : Converting existing unmanaged VMSS to managed VMSS.

    the scenario is
    1. we has an existing VMSS with unmanaged os disk already
    2. we want to convert to managed os disk in this VMSS.

    currently, it supports signle VM to migrate from unmanaged os disk to managed os disk, but it does not be supported for VMSS scenario.

    the current solution is we have to buildout a new VMSS with managed os disk and move our service from old VMSS to new VMSS, this has high risky(for exmaple, move the data from old VMSS to new VMSS, etc.),

  18. scheduled event is missing the delete/scale-in event for scale sets

    to properly demote cluster members during a scale-in or delete operation on a scale set node, the schedule event endpoint should provide the event-type delete or similar.

    then it would be possible, to take proper local actions before the node is gone.

  19. VMSS automatic OS upgrades should support Gen2 images

    There is nothing special abut the generation 2 images for Windows server. Features like automatic OS upgrades in virtual machine scale sets should support all operating systems, including Gen2 and Core images.

  20. Connection draining for VMSS before an upgrade

    VMSS should allow us to configure a custom script that can be run before performing an upgrade to ensure that all connections are drained before upgrading the image.

    Currently, the only way to do this is to use manual upgrades and RDP/remote powershell to each VM and take down the health probe, drain all the connections and then trigger the manual upgrade.

    This is not scalable with a large number of VMs and seems like a feature that could very easily be implemented on the VMSS.

    It would simply require custom script extensions that can be triggered manually by a…
