Here is a list of currently trending KB articles for NSX for vSphere.

NSX Distributed Firewall unfiltered rules may be deleted during the firewall rule publish operation in VMware NSX for vSphere 6.x (2141155)
Symptoms:

  • In Distributed Firewall Apply Filter mode in VMware NSX for vSphere 6.x, when filtered rules belonging to only one firewall section is modified and published by either Publish Section or Publish Changes or filtered rules belonging to multiple firewall sections are modified, you experienced these symptoms:

View Composer DiskFault: Disk customization failed due to an internal error

There’s a glitch some customers are encountering  whereby a Linked Clone desktop is created on vCenter Ok, but is deleted soon after vCenter complains about either “disposable” or “internal” .vmdk files this desktop. Creating and recomposing linked clone desktops fails on VMware Horizon View 6.1.x and all older releases after you have applied an upgrade patch.

On View Administrator, recomposing of pool fails with the error:

View Composer DiskFault: Disk customization failed due to an internal error

This issue occurs when older versions of Horizon View Composer prior to VMware Horizon 6.2 attempt to communicate with VMware ESXi hosts, but SSL v3 is disabled beginning in VMware ESXi 5.5 Update 3b and 6.0 Update 1 hosts.

We’ve created a KB article to address this scenario here: Linked Clone pool creation and recompositon fails with VMware Horizon View 6.1.x and older releases (2133018)

Note: There is a workaround provided in the KB but it is not advised to use it. The workaround makes the VMware ESXi 5.5/ 6.0 hosts vulnerable to security threats reported for SSL v3
