In this communication, we detail the top trending issues with VMware NSX for vSphere and provide you with helpful information on how to address the issues while we build a permanent fix. Please review the left column of the chart below to search for issues specific to your environment, and click on the hyperlinks to access more detailed information on each.

For additional up-to-date, top trending NSX issues, previous and current, please see KB Article Trending support issues in VMware NSX for vSphere 6.x (2131154).


NSX for vSphere Version

Component Issue Summary Resolution/Work-Around

KB Number

6.2.x , 6.3.x ESXi ESXi 5.5 and 6.0 hosts fail with a purple diagnostic screen (PSOD): VMCIEventDelayedDispatchCB@com which occurs due to race condition in dvfilter vmci socket deregistration. This issue is resolved in ESXi 5.5 Patch 8 and ESXi 6.0 Patch 3.

To work around this issue, uninstall the dvfilter-dsa driver.

KB : 2149242
6.3.x ESXi Hosts fails with a purple diagnostic screen when retrieving flows for ALG enabled protocols. To work around this issue, disable flow monitoring related features: IPFix, LiveFlow, Application Rule Manager, Flow monitoring-global flow collection. KB : 2149908


Top Issues + Resolution / Workaround

NSX for vSphere 6.3.x, 6.2.x

Issue #1:Process to change VXLAN port from 8472 to 4789 may fail or never complete.

Affected Version: 6.2.x, 6.3.x


  1. The process may fail or never complete while changing the VXLAN port from 8472 to 4789 (standard port assigned by IANA).

Resolution: To resolve the issue, run the REST API calls to check the status of the job and resume the change. For more details, please refer to KB2149996.


Issue #2: Guest Introspection USVM reports disk is full.

Affected Version: 6.3.x


  1. You receive an alert that the /var/log disk space is full or almost full on one or more of the Guest Introspection USVMs.
  2. This issue occurs as there is a problem with the internal log maintenance task that causes log files to grow indefinitely, eventually leading to a full disk situation.

Resolution: To work around this issuedelete the Guest Introspection USVM. Click on resolve to redeploy. For more details, please refer to KB2149856.


Issue #3: Distributed Firewall (DFW) packets hitting Default Rule instead of previous Rule allowing/blocking designated traffic.

Affected Version: 6.2.x, 6.3.x


  1. In examining Distributed Firewall (DFW) behavior, you may see some packets having a source, destination, and protocol (service) defined in a configured rule hitting the Default rule at the very end of the firewall rule list.
  2. In the dfwpktlogs or in LogInsight, you may see that the SYN packets and the ACK packets are being processed by the configured rule allowing/blocking the defined traffic.
  3. For the same traffic, you see RST and FIN ACK packets hitting the default block/allow rule, meaning that it is not hitting the previously-configured rule.

Resolution: To verify the rules ascribed to the filter or vNIC, type the vsipioctl getrules -f command. From this output, you can verify that the configured rule(s) are being applied to the virtual NIC as expected. For more details, please refer to KB2149818


Issue #4: VMs are removed from Exclusion List while adding new VM.

Affected Version: 6.2.x, 6.3.x


  1. When attempting to add a virtual machine to the NSX Manager’s Exclusion List to remove the DFW filter from the virtual machine, all other existing excluded virtual machines disappear from the Exclusion List.
  2. In the Web UI, after making the second or duplicate attempt, you may see an error similar to:
    Member: VM is already present in exclude list.

Resolution: To avoid this issue, refresh the UI page before adding the VM to the exclusion list. Refreshing the UI will clear any stale sessions and ensure that if another user has already added the VM, it is now reflected in the UI. For more details, please refer to KB2149997.


Issue #5: Backing up the NSX Manager to OpenSSH 7.x or later fails.

Affected Version: 6.2.x, 6.3.x


  1. This issue occurs because the SFTP jar files in the NSX Manager is out of date.

Resolution: To work around this issue, use OpenSSH version 6.x or earlier as your SFTP backup endpoint. For more details, please refer to KB2150053.


Trending KB

Issue #1: Re-installing NSX to upgrade vCNS Endpoint to NSX Guest Introspection.

Affected Version: 6.2.x, 6.3.x

Symptom: How to KB.

Resolution: The KB/Solution explains the procedure to upgrade from vCNS to NSX in the environments where vCNS is configured and used for Endpoint only. For more details, please refer to KB2150140.

VMware vCloud Director: 451 Research Impact Report Explores Expanded Capabilities for Service Providers

The introduction of vCloud Director 8.20 received analyst coverage from 451 Research, which took a closer look at the platform and the expanded capabilities enabling service providers to manage and operate virtual data centers (VDCs) for multiple customers.


Because vCloud Director is VMware&#rsquo;s strategic cloud management platform for service providers, it is designed to support the multi-tenancy and self-service requirements of public cloud (IaaS) and managed hosting providers. For enterprise customers with dedicated private clouds, VMware offers vRealize Automation to accelerate the deployment and management of applications and compute services.


The 451 Research Impact Report explored vCloud Director 8.20 and the new features informed by service provider feedback. These include a redesigned and re-implemented user portal, NSX® integration at the API level, and role management with organization and virtual machine affinity. Improved updating processes and automatic discovery and importation of vCenter virtual machines also contribute to a &#rsquo;stable, mature and capable cloud management platform&#rdquo; for service providers, according to 451 Research.


Lauded by 451 Research as &#rsquo;one of the most mature and able cloud management platforms extant&#rdquo; with &#rsquo;features tailored to its intended audience, and a track record of developing to answer demand from that specific audience,&#rdquo; vCloud Director is designed to meet the unique needs of service providers, including the rapid on-boarding of customers, monetization of services, and ability to differentiate in a highly competitive managed infrastructure market.


The Impact Report focuses on two areas specifically – the new user portal, and NSX integration, which 451 Research calls &#rsquo;a big deal&#rdquo; because it allows providers to tie NSX into billing and metering systems, which in turn enables rapid monetization of NSX-based services and future-proofs vCloud Director.


vCloud Director now integrates more closely with VMware NSX network virtualization, which means that service providers can abstract and define more NSX features for individual tenants while customers are able to customize network settings. This enables new, advanced service offerings that give tenants more power to manage their workloads.


Moving away from plugins, the new user portal for vCloud Director 8.20 takes advantage of industry-standard HTML5, enabling improved role-based access and controls, and better updates. With a new automated discovery tool service providers can dramatically improve customer on-boarding, especially in a hybrid environment.

[Video] Western Carolina University Extends Digital Workspace Solutions Campus-Wide

Nestled in the mountain town of Cullowhee, Western Carolina University (WCU) is the westernmost school in the University of North Carolina system. From the residence hall to the science lab, the school is extending digital workspace solutions to all corners of the campus and beyond.

WCU was the first campus in the University of North Carolina system to require its students to bring a computer to school. Now its 10,800 students show up with a variety of devices, from desktop and laptop computers to tablets and smartphones. The University needed a way to provide consistent and easy-to-access resources to each student, no matter what kind of device they have or whether the student is on or off campus.

Single Sign-on, Simple Access

The University tied their existing student portal to VMware Workspace ONE using SAML and VMware Identity Manager. Now only one login is needed to access apps, from Microsoft Office 365 to specialized programs for academics. With Workspace ONE, users log in once, then they can launch any desktop, RDSH or Software-as-a-Service (SaaS) applications they have access to.

&#rsquo;The fact that we can consistently and conveniently offer all this software is a huge benefit to our community.&#rdquo;
— Mark Ellersick, Technology Support Analyst, Western Carolina University

Apps are distributed and customized with VMware App Volumes. App Volumes customizes desktops based on student profiles. When a student finishes a class, their access to apps for that class is withdrawn—saving money for WCU&#rsquo;s IT department.

Any App at Any Time

VMware Horizon provides nonpersistent virtual desktops for students. &#rsquo;The great thing about the technology is that students don&#rsquo;t notice it,&#rdquo; said Mark. &#rsquo;They walk into a lab, log in and do their work. When they walk out of that lab and go to their residence, or even to another town or state, they can access that same resource. Now the lab is open 24 hours a day, seven days a week.&#rdquo;

To access published apps, the WCU IT staff uses Horizon&#rsquo;s RDS Hosted Applications feature. If someone doesn&#rsquo;t need access to a full desktop (McGraw cites the University&#rsquo;s IT ticketing system, as an example) they simply authenticate to Horizon and then launch a published app, save files and use network resources from a remote RDSH server as if it were on their local device.

With VMware User Environment Manager, dynamic personalization management manages specific experiences around locations or user groups. For example, campus printers are made available based on users&#rsquo; locations, and UEM makes it easy to add or take away card-key access to electronic locks on campus.

High-Powered Graphics—Not Just for Engineering Class

WCU uses products from VMware partner NVIDIA for both academic and personal computing. NVIDIA GRID cards bring the power of the NVIDIA graphics processing unit (GPU) to Horizon virtual desktops, speeding graphics performance and rendering for applications such as 3D modeling and computer-aided design. To support all the streaming services and videos that students watch in their free time, the WCU IT team is also expanding NVIDIA cards to each host box they deploy.

Windows 10 Made Easy

WCU is finding that virtualization is a big help in getting their community acclimated to Windows 10 as the University begins to upgrade.

Patrick McGraw, virtualization and tier one engineer, said, &#rsquo;Some people are hesitant about adopting Windows 10 because it&#rsquo;s a big change. We created a pool of Windows 10 desktops so people can play with the software and get to know it. Then when we upgrade their machine, they&#rsquo;re already used to the technology, and that makes them happy. We&#rsquo;ve gotten a lot of positive responses.&#rdquo;

&#rsquo;We&#rsquo;re excited, as a university and as an IT department, to give students a consistent experience and really level the playing field. We&#rsquo;re breaking down barriers and making resources more accessible. We&#rsquo;re excited that we can bring everything together in a very intuitive and easy-to-use package.&#rdquo;
