Unable to login to the vSphere Web Client after VCSA 6.0U1 upgrade to 6.0U2

After an upgrade of a VCSA 6.0U1 to 6.0U2, I was unable to login to the vSphere web client. Also the login screen was a little bit messed-up like you can see on the screenshot below. When I entered a login name and a password it directly showed User name and password are required, like […]

Configure a HTTPS proxy for vCenter VAMI updates

I just needed to update a customer’s vCenter server from 6.0U1 to 6.0U2. As I didn´t have access to the vSphere cluster where the vCenter VM itself was running, I tried the update option via the VAMI interface. The vCenter was unable to directly connect to the internet but I got a proxy URL from […]

VMware vSphere 6: Hidden C# client enhancement

I have seen multiple vSphere environments in the last couple of months, which had a lower EVC baseline as necessary configured with vSphere 5.5. The reason in these cases always was that the customer used the vSphere C #client for all kind of configurations. If you have an Intel Ivy Bridge CPU in your ESXi […]

VMware vCenter Orchestrator (vCO) installation ‘gotchas’

I needed a portable vCO lab environment, so I quickly installed the vCenter Server appliance, a ESXi host and the vCO appliance (5.5.2) on top of my notebook with VMware workstation.

Trendmicro Deep Security: Filterdriver for vSphere 5.5 Update Manager

It seems that Trendmicro has no updated package of the filterdrivers for Deep Security with vShield Endpoint for vSphere 5.5. At least the zip package you can download from the official site is for vSphere 5.0. The VIB file which is contained within this package works fine with 5.5 and is also supported according to […]

vCNS: Empty Summary Page

I recently performed an vSphere Upgrade to 5.5 including vShield Manager / vCNS. Before I started with the vShield Manager Upgrade I wanted to check the status of the Endpoint service on the ESXi Hosts. If you select a host within vShield Manager and navigate to the summary tab you normally see the status of […]

Storage vMotion: Invailid configuration for device ’12’

During one of my latest vSphere projects I came across a strange error message. In a brand new vSphere 5.5 environment I added a existing VM from a datastore, which was also connected to the old vSphere 4.1 environment. Previously the VM for sure got shutdown from the old environment. When I tried to storage […]

How to fake a VMs guest OS CPUID

For the most software products the license verification is done with license keys. During my time in the IT I have also seen some products, where the license is tied to the underlying hardware of your server. Mostly this is realized with license files, which include the ID of your CPU. The application checks if […]

Nested ESXi – VALIDATE_HOST_HW ERROR: vendor VIB for HP found, but host is VMware, Inc

During the last couple of months I noticed more and more people got to my blog by searching for a term like „vendor vib for hp found but host is vmware”. This error message during the installation of a nested ESXi host was discussed in the comment section of my article vSphere 5.1: Quick Start […]

Disk consolidation: Unable to access file

Last week a customer called me with a strange behavior of some VMs. He noticed that his backup software (HP Data Protector) left snapshots on some VMs. After he manually removed it, he got the message “Virtual machine disk consolidation is needed”. Starting the consolidation process always ended up with the pop-up you can see […]
