After the appointment as VMware vExpert by VMware itself, I continue my series of successes. Yep, now I am officially a certified VMware vSAN Specialist.
I got 3 Dell R730 servers on which VMware ESXi 7.0 U3 should be installed normally. During the installation I encountered the following error message: Well, we all know how it feels when we see PSOD so a Purple Screen of Death – pretty much panic. But since we are experienced VMware administrators, we look at any PSODs soberly and go into troubleshooting. 😉 As […]
Yes, Ladies and Gentleman today I got the announcement by VMware that I am officially a VMware vExpert: I am proud to be part of this Expertise Association and I want to thank to all VMware Brothers in Arms in my Team, especially Marc Huppert as my biggest supporter. 😎
If you want to make VM creation easier, you may have VM templates in your VMware vCenter, in addition to automation tools. Accordingly, I wanted to use a Windows Server 2019 template and build a VM from it. In the process, I ran into an error that had not happened to me before: The error message says: Module CPUID power on failed. Failed to start […]
In this post we will see on how you can create VM Customization Specifications policy in VMware vCenter for a Windows Server 2019 VM Template. VM Customization Specifications allows you to configure few options for your Guest OS which is running inside your VM. You can configure things like Timezone, Admin Password, Licesing, Network etc. The most important requirement to apply this policies is, that […]
In VMware ESXi 7.0 the Host Client Web Interface session timeouts automatically every 15 minutes and then you have to log back in to the ESXi Host Client Web Interface again. To avoid this tedious situation you can increase the session timeout changing an advanced configuration parameter in the ESXi Host Client Web Interface. !!! WARNING !!! For security reasons, timouts should be kept low and not removed. Using your […]
This article provides steps to back up and restore the ESXi host configuration. There are two conditions that need to be satisfied: 1 – The destination build number of the host matches the build from which the backup was taken.2 – The UUID of the host remains the same. You can backup and restore the host configuration using one of these methods: ESXi Command line […]
TPM stands for Trusted Platform Module. It is a chip that provides basic security functions on a hardware basis. It can be used to ensure the integrity of a system and platforms such as computers and servers or other electronic devices like smartphones. The chip is protected against manipulation by security mechanisms and, for example, generates, provides, stores or controls the use of cryptographic keys. […]
No matter what the situation, there may be a requirement to change the vNIC of a VM from E1000 to VMXNET3. In my case I have changed my whole network infrastructure to 10 Gbit, Linux VMs are easy to migrate but Windows VMs are a little bit problematic, so I want to show you with this example how it works. Using the VMXNET Generation 3 (VMXNET3) […]
In this project we had a stack consisting of 3 individual VMware ESXi 5.5 servers. These are the Cisco UCS C240M4S2 model with Intel XEON v3 CPUs. As mentioned earlier, 09/18/2020 was considered End of Support for ESXi 5.5 and so most are now forced to update their environments to the latest version. First we check via VMware Compatibility Guide if the hardware component, BIOS […]
