Several people are disabling IPv6 support in ESXi for different reasons: because of the minimum privilege principle (if you are not using a service, why you have to keep it enabled?) or simple because they don’t want any IPv6 address in the network. On Linux and Windows systems is become very difficult disable it and Microsoft itself does not recommend disabling IPV6: ” We do not recommend that you disable IPv6 or its components, or some Windows components may not function.” (https://support.microsoft.com/en-us/kb/929852)

VMware vSphere 6.5 Update 1 has been released on July 27, 2017 with several bug fix, some improvements, but also some interesting changing in maximum numbers (for vCenter in linked-mode) and an interesting news for the Foundation edition that now can manage up to 4 nodes (and not only 3 nodes like in the past). Seems a minor improvement, but demostrare how VMware takes care of its customers. In discussions with customers with smaller environments, VMware has received feedback that 3 host environments were too small in many cases, and just another hosts could be enough […]

One year ago there were some rumors and doubts about the future of Workstation and Fusion product, due to the laying off some employees. from the related teams. But Workstation 12 has got some updates and also a 12.5 version. And now there is also a new VMware Workstation Technology Preview 2017 release! That’s a good message and sign for a product that it’s really useful on the client part and can be a good companion of the vSphere suite (on the server and host part).

The new VMware Virtual SAN (or vSAN) 6.6 adds several enchaments and new features as described in the announce notes. Some interesting news are related to security aspects and how data-at-rest could be protected: one option could be new vSphere 6.5 VM encryption format but now it’s also possible use the native vSAN encryption. Duncan’s post explains the difference of those two approaches.

The new VMware Virtual SAN (or vSAN) 6.6 adds several enchaments and new features as described in the announce notes. Most of those aspects are related to data and cluster resiliency (as expected by a storage solution), including:

VMware has announced the intention to acquire Wavefront, a leading metrics monitoring service for cloud and modern application environments. In this way VMware is going to increase its Cross-Cloud management products and services including costing, discovery, monitoring, root cause analysis, and visualization.

VMware has announced the discontinuation of its third party virtual switch (vSwitch) program, and plans to deprecate the VMware vSphere APIs used by third party switches in the release following vSphere 6.5 Update 1. Subsequent vSphere versions will have the third party vSwitch APIs completely removed and third party vSwitches will no longer work. In the past years, VMware has recommended the Nexus 1000V users to move into the VMware vSphere Distributed Switch to avoid future problems, now it’s clear the product version where you can go.

VMware is announcing the End of Availability (EOA) of vSphere Data Protection (VDP), the backup program integrated with vSphere suite and included with the Essential Plus license. VMware vSphere 6.5 is the last release to include vSphere Data Protection and future vSphere releases will no longer include this product. VMware will focusing its investments on vSphere Storage APIs – Data Protection to further strengthen the vSphere backup partner ecosystem that provides better 3rd part native backup products. For sure it’s a great sign for the backup ecosystem.

Recently VMware has released a few security patches that will prevent a guest from execute code on the ESXi host and breaking the isolation of a virtual machine. This has been possible based on heap buffer overflow and uninitialized stack memory usage in SVGA, using this bug may allow a guest to execute code on the host. Note that this particular issue impacts ESXi 6.0 or later as also latest version of VMware Workstation, Player and Fusion.

If you are using the legacy VMware vSphere Client on Windows 10 you may have some issues with the VM console that display only a part of the screen and leave blank other parts. You can use other clients (like the Web Client if you have vCenter or the Host UI if you have at least ESXi 6.0U2), but maybe you will have other issues (for example on ESXi 6.0 host UI console mouse may not work well or not at all).

VMware has updated their supported Products list with a new version (updated at February 1,2017) of VMware Lifecycle Product Matrix document. Finally this document has become smart and short, with few pages and highlighted in a right way both the products version is within 6 months of End of General Support or End of Technical Guidance and also products version that has gone past its End of General Support.
