Reading Time: 2 minutesIf 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: 3 minutesOne common way to backup the VMware vCenter Server Appliance (VCSA) is to manage as a common VM and use a backup solution to backup (and restore) the entire VM. But it’s approach does not always work, for example in the case of a database corruption the VM restore could be not working. Starting with vSphere 6.5 and the new VCSA 6.5 was possible to use also a native backup solution integrated with the vCenter Server Appliance Management Interface (VAMI). But it was a manual operation (some scripts are available to automate and schedule it).

Reading Time: 2 minutesVMware vSphere 6.5 it’s quite popolar now, considering the deadline for the version 5.5 in this year and the direct upgrade path from v5.5 to v6.5. But maybe not everybody want to update vSphere 6.5 to Update 2, considering that there will be no upgrade path (yet) to version 6.7 and maybe other minor issues due to the backport of some features.

Reading Time: 3 minutesVMware has released (on Feb, 15th) a new vCSA version: vCenter Server 6.5 U1f, with build number 7801515. This release patches the vCSA operating system (Photon OS) mainly against two vulnerabilities: bounds-check bypass (Spectre-1, CVE-2017-5753) and rogue data cache load issues (Meltdown, CVE-2017-5754). As of now, there is still no patch for branch target injection vulnerability (Spectre-2, CVE-2017-5715). VMware has also updated the security advisory dealing with all of its virtual appliances updates for Spectre and Meltdown vulnerabilities, VMSA-2018-0007. But note that VMSA-2018-0004.2 has not been updated yet, and it still report that the suggested version for […]

Reading Time: 1 minuteThis is an article realized for StarWind blog and focused on the pro and cons of an upgrade to vSphere 6.5. See also the original post. VMware vSphere 6.5 is the latest version of the enterprise server virtual platform from VMware, but the new beta it’s already there for testers. Actually the next version it’s (in the beta) and you can register at https://secure.vmware.com/43478_vSphere_Beta_Reg.

Reading Time: 8 minutesNote that this post has an updated version: Is the HTML5-based vSphere Client finally mature? VMware vSphere, during its history and the different versions, has got several types of GUI clients. One of the most used (not the first, but the standard one since Virtual Infrastructure 3.0) was the vSphere Client for Windows. But on May 2016 VMware has announced that the Legacy C# Client (aka thick client, desktop client, or vSphere Client) will no longer be available with the vSphere 6.5 release, replaced by web-based clients. With VMware vSphere 6.5 there are mainly two […]

Reading Time: 2 minutesVMware vSphere 6.0 has got some issues, like the several related to CBT and data protection, during the first years of its life. Mostly is finally resolved, but you may still have strange issuesespecially during the upgrade procedure (most when you start from a vSphere 5.1 version). I notice, after an upgrade, also a strange behavior with vMotion where live VM migration fails with this error: A general system error occurred: PBM error occurred during PreMigrateCheckCallback: No connection could be made because the target machine actively refused it.

Reading Time: 3 minutesVMware vCenter Server is a critical component in a vSphere environment, because is needed to provide some cluster functionality. A good design and deployment (that are different from version 5.x and 6.0) are important to avoid possible issues. And, of couse, a good availability of this kind of service. Troubleshoot this component is not always simple and there are a lot of VMware KB articles, but not a good single resource from where start in this kind of tasks. The purpose of this book is really clear from the title itself (vCenter troubleshooting) and the […]

Reading Time: 7 minutesIf you plan to build a lab for vSphere 6.0 you can use all the approches for vSphere 5.x (see also Building a vSphere 5 lab): usually using a nested environment (or three physical systems, if you have) as a common platform. Of course, the other way to test new products it’s just use the VMware Hands on Labs that you can also “broke” or use in a different path compared to the one suggested by the guide. But having a local environment permit more flexibility and more time for testing or learning. The big […]

Reading Time: 13 minutesWith the new VMware vSphere 6.0 there are a lot of changes, and some of them are in the new vCenter architecture both for the Windows installable version and the virtual appliance (vCSA) version. For this reason the design aspects and the deployment scenarios are changed from the previous version (see VMware vCenter 5.5 design). Windows vCenter installation experience has been enhanced with additional capabilities including custom ports, custom paths, uninstall and error messaging improvements and vCenter Server Appliance (vCSA) now has a guided installer. Furthermore, all upgrade paths from Windows vCenter 5.0 and up […]

Reading Time: 8 minutesIn previous versions of vSphere, the vCenter Server was not suitable to provide directly cloud based functions: vCloud Director was the way to build a Software Defined DataCenter (SDDC) at the top of vSphere and provide more functions and concepts that were not available in vCenter. But, during the VMworld 2013, VMware introduced a new product strategy and direction for vCloud Director (vCD): VMware would like to move forward with a plan to converge vCD functionality into the vSphere and vCloud Automation Center (vCAC) product lines or (as another direction) in the virtualization platform (that […]

Reading Time: 10 minutesThe new VMware vSphere Suite 6.0 brings several changes and new features, but the installation phases remain still similar with the previous versions. The big changes are in the vCenter deployment type both for the installable and the appliance version and the new VUM client… all the other parts of the installation remain similar  with only few notes.
