After applying the patches (Aug 14, 2018), a warning message showed on patched ESXi hosts: esx.problem.hyperthreading.unmitigated According to the release notes, VMware introduced a new Advanced Configuration on the hosts to mitigate the new hyperthreading attacks, however, it states there's a performance hit that cannot be ignored. Re: ESXI Problem Hyperthreading unmitigated msripada May 31, 2019 6:37 AM ( in response to insearchof ) pls check the KB VMware Knowledge Base.

Issue description - If you are upgrading your VMware environment from 5x to 6x specially 6.7. let me tell you this differently, After the ESXi upgrade from 5.5 to 6.5 and then finally 6.7, (because you cannot upgrade ESXi 5x to ESXi 6.7 directly), everything seems to be perfect and there is no issues, and then you chose to patch the ESXI host with the latest available patches.

VCenter Server, ESXi, Workstation, and Fusion updates include Hypervisor-Specific Mitigations for L1 Terminal Fault - VMM. This issue may allow a malicious VM running on a given CPU core to effectively read the hypervisor’s or another VM’s privileged information that resides sequentially or concurrently in the same core’s L1 Data cache. Esx.problem.hyperthreading.unmitigated Cause The ESXi patches available in VMSA-2018-0020 to mitigate CVE-2018-3646 introduced a new notification to indicate the remediation status of the 'L1 Terminal Fault' (L1TF - VMM) vulnerability.

After applying the patches in VMSA-2018-0020 to an ESXi host vCenter Server displays one of these messages:

XXX esx.problem.hyperthreading.unmitigated.formatonhost not found XXX

or

esx.problem.hyperthreading.unmitigated

You can see the screenshot below.

Reason behind the notification.

It happens when an ESXi hosts is updated before vCenter Server. For more info Click here

Solution – It has two solutions or workaround

1. Upgrade your vCenter to latest patches, version.

2. If upgrading vCenter is not possible or if it is not allowed in your environment then follow below steps to disable the notifications.

Change the changing the value of the ESXi advanced option UserVars.SuppressHyperthreadWarning from 0 to 1.

See the scree shot below.

If it solved your issue then please give a thumbs up to this article and share with others.

The ESXi Embedded Host Client is a native HTML and JavaScript application and is served directly from your ESXi host! It should perform much better than any of the existing solutions.

Please note that the Host Client cannot be used to manage vCenter.

We welcome any feedback and bug reports. You can post your feedback here on the VMware Labs site, in the VMware.com community forums, or using the Host Client's built-in Feedback tool under the Help menu.

Download the VIB here. If you are looking to automate installation of the latest VIB, we also provide a copy of the latest VIB here.

Known Issues

• On hosts using ESXi 6.0 Update 1 or lower and ESXi 5.5 Patch 8 or lower which are assigned a VMware vSphere Hypervisor license (the free license from VMware.com), all modification operations will fail silently. This issue has been resolved in ESXi 6.0 U2 and 5.5 Patch 8.
• Hosts with ESXi 6.0 before Update 2 which have a sub-domain name with a combined cookie size of >8KB in-browser web console sessions may fail to initialize. A workaround is to clear cookies or run the host client in an incognito-type window, or alternatively, use the standalone VMware Remote Console application.
• For ESXi 5.5 hosts, in-browser consoles are not supported. Please use VMware Remote Console (VMRD) to access guest VM consoles.
• For ESXi 5.5 hosts before Update 2, you must ensure to append a trailing / (forward slash) to the URL after /ui. The URL must be https://<esxhost>/ui/

What's missing?

The Embedded Host Client is currently undergoing development. We are working hard to bring the functionality level to that of the vSphere Client, but we're not there yet. Here's what we know is missing:

• Resource pool management
• Comprehensive performance chart UI with access to all performance counters
• Exporting performance counter data to Excel/CSV
• Multi-NIC vMotion configuration
• Deploying VMs from a URL
• Exporting VMs to an OVA

Offline Bundles

Offline bundles are packages that can be loaded into VMware Update Manager to facilitate easy installation of the Host Client onto a cluster of ESXi Hosts

VMware Remote Console VIBs

Installation of the VMRC VIBs is optional and intended to facilitate downloading VMRC in situations where access to VMware.com is not possible. The VIBs are installed into the /locker partition of your host's locally attached disk. This partition has limited space, and so care should be taken to ensure that sufficient space is available. Each VIB is roughly 20 MB in size.

Open source disclosure

We provide an open source disclosure package for the required packages.

A complete open source disclosure can be found in the About dialog of the Host Client.

Feedback

We welcome any feedback or bug reports. Please post here in the Comments or Bugs tab or in the VMware Technology Network community forum.

You must have a web browser installed with JavaScript and cookies enabled.

Installation

The easiest way to install a VIB is to download it directly on the ESXi host. Alternatively, you can download it to your local machine and use scp to push it to your ESXi Host.

If your ESXi host has internet access, you can install directly from URL.

where <URL> is the URL to the VIB from the VMware.com Flings website or somewhere you have locally hosted it.

If the VIB installation completes successfully, you should now be able to navigate a web browser to https://<esx ip or hostname>/ui and the login page should be displayed.

If you have downloaded the VIB to your local machine, you will need to push it to ESXi using scp.

You may need to clear the cache in your browser to see the updated version.

To remove the ESXi embedded host client from your ESXi host, you can use esxcli.
