Reading Time: 4 minutes If you are running VMware vSphere 5.5 or 6.x you may have some issues with VM snapshots with the risk that VMs may report guest data inconsistencies! Not funny at all and potentially a critical problem that must be planned, considering that VM snapshots are used by all VM native backup products! And more serious that the cosmetic snapshot “issue” in VMware vSphere 6.0 using the vSphere C# Client. This issue is still open for vSphere 5.5 (and probably will remain un-fixed considerind that v5.5 is in End of General Support), 6.0 and 6.5.

Reading Time: 3 minutes VMware vSphere 5.5 is really close to its End of Support, that will mean no more updates and possible limited support from VMware. The End of General Support for vSphere 5.5 is September 19, 2018. To maintain your full level of support and subscription services, VMware recommends upgrading to vSphere 6.5, or to a newer version.

Reading Time: 3 minutes Three years ago, VMware has decided to make VMware Tools an independent package, with a separate lifecycle and available in the MyVMware download page as a separated package. Separated and independent from VMware Fusion, Workstation and ESXi virtualization solutions! Seems good, but on vSphere environment, this can make some confusion considering that you have the VMware Tools bundled with ESXi and the standalone VMware Tools usually with a bigger version and independent also by the version of vSphere!

Reading Time: 2 minutes There are a lot of different possible reasons why a VM does not power on a VMware vSphere infrastructure, but usually, the error message can really help to found the reason or the root cause. Maybe not available resources, maybe some files that are missing, maybe some incompatibility… But normally you can put the error message and found the proper VMware KB that can help you.

Reading Time: 5 minutes VMware Tools are a set of utilities installed in the guest operating system that improve the control of the virtual machine making the administration easier, can increase the overall performance providing paravirtualized drivers and add also new features and capabilities (for example the snapshots with quiesciencing). Usually VMware Tools are included with ESXi deployment, but starting with November 2nd, 2015 there are also a standalone version of VMware Tools that can be downloaded as a VMware Tools packages ZIP or TAR.GZ file (or also a VIB file). Downloads are available at this link.

Reading Time: 5 minutes As usual, VMworld has several announcements, and for the second year in a row, there are some important announcements about the core virtualization platform: VMware vSphere. First news is a not surprising new vSphere 6.7 Update 1… At the begin of the year, my bet was that vSphere 6.7 was announced during VMworld US and maybe vSphere 6.7 Update 1 at VMworld EU, but seems that the releasing of the product has been accelerated (in my opinion to accelerate vSAN growing).

Reading Time: 6 minutes The new vSphere Client in HTML5 introduced with vSphere 6.5 was originally a Flings project called: vSphere HTML5 Web Client. The name is inconsistent now, but the Flings project mantain the original name to avoid something like ‘vSphere Client Fling’ and also to keep its independed devel path. And on August 22, 2018 a new release of the Fling version has been released: v3.41 – Build 9687895.

Reading Time: 3 minutes If you still are using the Windows based vCenter Server with a SQL Server database you may have some login issues, due to a recent Windows update (released on July 10, 2018). You will have some errors in the SQL Server part with SQL startup issues due to “TCP port is already in use” errors. This is caused by a regression in the TCP/IP functions that manages the TCP port pool introduced in the July 10, 2018 Windows updates for Windows 7/Server 2008 R2 and Windows 8.1/Server 2012 R2.

Reading Time: 7 minutes The L1 Terminal Fault (aka Foreshadow) bug is another speculative execution side channel attack that affects Intel Core processors and Intel Xeon processors only. For VMware vSphere, there are some patches available as described in this document: VMSA-2018-0020. All patches have been released on August, 14th 2018.

Reading Time: 3 minutes Dell EMC OpenManage Server Administrator (OMSA) is a complementary tool that provides a comprehensive, one-to-one systems management solution in two ways: from an integrated, web browser-based graphical user interface (GUI) and from a command line interface (CLI) through the operating system. Usually, you should add it to each bare metal system, unless you are using other management tools. But also if you are using Open Manage Essential (OME) or similar, OMSA provide some unique and powerful features, like the access to the BIOS settings.
