Collecting diagnostic information for VMware products
VMware vSphere ESXi VMware vCenter Server VMware Desktop Hypervisor VMware NSX Networking VMware Aria Suite VMware Cloud Director VMware Live Recovery VMware vSAN VMware Integrated OpenStack VMware Technical Support routinely requests diagnostic information from you when a support request is handled. This diagnostic information contains product specific logs, configuration files, and data appropri
VMware KB: Choosing a Port binding type
When choosing a port binding type, consider how you want to connect your virtual machines and virtual network adapters to a vDS and how you intend to use your virtual machines. Port binding type, along with all other vDS and port group configuration, can be set only through vCenter Server.

Setting a static MAC address for a virtual NIC
I am having a MAC address conflict on one of my virtual machines, or I need to set the MAC address for one of my virtual network adapters manually. Why and how would I do this? Note: This process detailed in this article applies to ESX 2.5 and earlier. For information on MAC address generation in later versions, see: ESX/ESXi 3.x: The Setting Up MAC Addresses section of the ESX Server 3 Configurat

Low virtual network I/O performance with Intel 1Gbps NIC using igb driver
The InterruptThrottleRate parameter of the igb driver that regulates the rate at which interrupts are generated by the adapter affects network and system performance. The igb driver uses dynamic conservative mode (setting 3) as the default value in which it dynamically adjusts the InterruptThrottleRate based on the incoming traffic. The valid range of the InterruptThrottleRate is the following: 0
Multihoming on ESXi
Multihoming in a VMkernel networking context means that there are multiple VMkernel adapters in a single TCP/IP stack. Note: There can be multiple TCP/IP stacks each with a single vmknic. That is not considered multihoming. Multihoming should not be confused with iSCSI port-binding, Multi-NIC vMotion, or the use of multiple Netstacks / TCP/IP stacks.

Symptoms: When running a virtual machine with Windows 2008 R2, Red Hat Enterprise Linux or Solaris 10 64-bit on either ESXi, Workstation, or Fusion, you experience one of these symptoms: Windows 2008 R2 blue screen events: 0x0000000a - IRQL_NOT_LESS_OR_EQUAL 0x0000001a - MEMORY_MANAGEMENT 0x000000fc - ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY 0x0000004e - PFN_LIST_CORRUPT 0x00000050 - PAGE_FAULT_IN_NO
Understanding the VMFS heap eviction process in ESXi 5.5 and later
This article explains how the heap eviction process improved in ESXi 5.5 and later. For earlier versions of ESXi, see ESXi/ESX host reports VMFS heap warnings when hosting virtual machines that collectively use 4 TB or 20 TB of virtual disk storage (1004424). To address an issue with VMFS heap while accessing 30 TB of open files from a single ESXi host, ESXi 5.0 Patch 05 and ESXi 5.1 Update 1 intr
Resolving OpenSSL Heartbleed for ESXi 5.5 - CVE-2014-0160
ESXi 5.5 and ESXi 5.5 Update1 hosts require an update to resolve the OpenSSL Heartbleed vulnerability found in the OpenSSL 1.0.1 library. Apply this patch immediately to update OpenSSL library to fix the critical security vulnerability reported in CVE-2014- 0160. Details on this vulnerability can be found in VMware Security AdvisoryVMSA-2014-0004. For details on impact of OpenSSL Heartbleed vulner
