Microsoft Ends 2018 With Failed Windows Update

Theresa Miller - Tue, 12/11/2018 - 06:30

Many home users of Microsoft products almost take for granted their Windows Update will operate correctly.  For those of you keeping score, Microsoft pulled the Windows Update from October 2018 because it was unexpectedly deleting user files.  To finish the year with a bang, Microsoft pulled yet another failed Windows Update in December of 2018 to end […]

Looking at the Hyper-V Event Log (January 2018 edition)

Microsoft Virtualisation Blog - Tue, 01/23/2018 - 22:57

Hyper-V has changed over the last few years and so has our event log structure. With that in mind, here is an update of Ben’s original post in 2009 (“Looking at the Hyper-V Event Log”).

This post gives a short overview on the different Windows event log channels that Hyper-V uses. It can be used as a reference to better understand which event channels might be relevant for different purposes.

As a general guidance you should start with the Hyper-V-VMMS and Hyper-V-Worker event channels when analyzing a failure. For migration-related events it makes sense to look at the event logs both on the source and destination node.

Below are the current event log channels for Hyper-V. Using “Event Viewer” you can find them under “Applications and Services Logs”, “Microsoft”, “Windows”.
If you would like to collect events from these channels and consolidate them into a single file, we’ve published a HyperVLogs PowerShell module to help.

Event Channel Category Description Hyper-V-Compute Events from the Host Compute Service (HCS) are collected here. The HCS is a low-level management API. Hyper-V-Config This section is for anything that relates to virtual machine configuration files. If you have a missing or corrupt virtual machine configuration file – there will be entries here that tell you all about it. Hyper-V-Guest-Drivers Look at this section if you are experiencing issues with VM integration components. Hyper-V-High-Availability Hyper-V clustering-related events are collected in this section. Hyper-V-Hypervisor This section is used for hypervisor specific events. You will usually only need to look here if the hypervisor fails to start – then you can get detailed information here. Hyper-V-StorageVSP Events from the Storage Virtualization Service Provider. Typically you would look at these when you want to debug low-level storage operations for a virtual machine. Hyper-V-VID These are events form the Virtualization Infrastructure Driver. Look here if you experience issues with memory assignment, e.g. dynamic memory, or changing static memory while the VM is running. Hyper-V-VMMS Events from the virtual machine management service can be found here. When VMs are not starting properly, or VM migrations fail, this would be a good source to start investigating. Hyper-V-VmSwitch These channels contain events from the virtual network switches. Hyper-V-Worker This section contains events from the worker process that is used for the actual running of the virtual machine. You will see events related to startup and shutdown of the VM here. Hyper-V-Shared-VHDX Events specific to virtual hard disks that can be shared between several virtual machines. If you are using shared VHDs this event channel can provide more detail in case of a failure. Hyper-V-VMSP The VM security process (VMSP) is used to provide secured virtual devices like the virtual TPM module to the VM. Hyper-V-VfpExt Events form the Virtual Filtering Platform (VFP) which is part of the Software Defined Networking Stack. VHDMP Events from operations on virtual hard disk files (e.g. creation, merging) go here.

Please note: some of these only contain analytic/debug logs that need to be enabled separately and not all channels exist on Windows client. To enable the analytic/debug logs, you can use the HyperVLogs PowerShell module.

Alles Gute,

Lars

A smaller Windows Server Core Container with better Application Compatibility

Microsoft Virtualisation Blog - Mon, 01/22/2018 - 19:04

In Windows Server Insider Preview Build 17074 released on Tuesday Jan 16, 2018, there are some exciting improvements to Windows Server containers that we’d like to share with you.  We’d love for you to test out the build, especially the Windows Server Core container image, and give us feedback!

Windows Server Core Container Base Image Size Reduced to 1.58GB!

You told us that the size of the Server Core container image affects your deployment times, takes too long to pull down and takes up too much space on your laptops and servers alike.  In our first Semi-Annual Channel release, Windows Server, version 1709, we made some great progress reducing the size by 60% and your excitement was noted.  We’ve continued to actively look for additional space savings while balancing application compatibility. It’s not easy but we are committed.

There are two main directions we looked at:

1)      Architecture optimization to reduce duplicate payloads

 We are always looking for way to optimize our architecture. In Windows Server, version 1709 along with the substantial reduction in Server Core container image, we also made some substantial reductions in the Nano Server container image (dropping it below 100MB).  In doing that work we identified that some of the same architecture could be leveraged with Server Core container. In partnership with other teams in Windows, we were able to implement changes in our build process to take advantage of those improvements.  The great part about this work is that you should not notice any differences in application compatibility or experiences other than a nice reduction in size and some performance improvements.

2)      Removing unused optional components

We looked at all the various roles, features and optional components available in Server Core and broke them down into a few buckets in terms of usage:  frequently in containers, rarely in containers, those that we don’t believe are being used and those that are not supported in containers.  We leveraged several data sources to help categorize this list. First, those of you that have telemetry enabled, thank you! That anonymized data is invaluable to these exercises. Second was publicly available dockerfiles/images and of course feedback from GitHub issues and forums.  Third, the roles or features that are not even supported in containers were easy to make a call and remove. Lastly, we also removed roles and features we do not see evidence of customers using.  We could do more in this space in the future but really need your feedback (telemetry is also very much appreciated) to help guide what can be removed or separated.

So, here are the numbers on Windows Server Core container size if you are curious:

  • 1.58GB, download size, 30% reduction from Windows Server, version 1709
  • 3.61GB, on disk size, 20% reduction from Windows Server, version 1709

MSMQ now installs in a Windows Server Core container

MSMQ has been one of the top asks we heard from you, and ranks very high on Windows Server User Voice here. In this release, we were able to partner with our Kernel team and make the change which was not trivial. We are happy to announce now it installs! And passed our in-house Application Compatibility test. Woohoo!

However, there are many different use cases and ways customers have used MSMQ. So please do try it out and let us know if it indeed works for you.

A Few Other Key App Compatibility Bug Fixes:

  • We fixed the issue reported on GitHub that services running in containers do not receive shutdown notification.

https://github.com/moby/moby/issues/25982

  • We fixed this issue reported on GitHub and User Voice related to BitLocker and FDVDenyWriteAccess policy: Users were not able to run basic Docker commands like Docker Pull.

https://github.com/Microsoft/Virtualization-Documentation/issues/530

https://github.com/Microsoft/Virtualization-Documentation/issues/355

https://windowsserver.uservoice.com/forums/304624-containers/suggestions/18544312-fix-docker-load-pull-build-issue-when-bitlocker-is

  • We fixed a few issues reported on GitHub related to mounting directories between hosts and containers.

https://github.com/moby/moby/issues/30556

https://github.com/git-for-windows/git/issues/1007

We are so excited and proud of what we have done so far to listen to your voice, continuously optimize Server Core container size and performance, and fix top application compatibility issues to make your Windows Container experience better and meet your business needs better. We love hearing how you are using Windows containers, and we know there is still plenty of opportunities ahead of us to make them even faster and better. Fun journey ahead of us!

Thank you.
