When you try to install ESXi 7.0 or 8.0 on a system with a 12th Gen Intel CPU, the installation fails with a purple diagnostics screen: HW feature incompatibility detected; cannot start Fatal CPU mismatch on feature “Hyperthreads per core” Fatal CPU mismatch on feature “Cores per package” Fatal CPU mismatch on feature “Cores per […]
Having our vCenter servers in an enhanced link mode configuration is great, since everything is in one console, but there are situations where one of the vCenter servers or External Platform Service Controllers (PSC) just die, it’s improperly removed from the infrastructure during decommission, or you just want to break the Enhanced Link Mode configuration (ELM) between one or […]

Introduction In the previous article, I have shared a working algorithm on replacing the ESXi SSL certificate with a self-signed one, but, as you know well, there’s always room for perfection. So, I have been practicing with a more universal scenario that could also work with a domain infrastructure and domain certificate services. That’s what I […]
This is a template outline I have used several times and am very happy with it. It should work great for you and if not then let me know. I did this with vSphere 6.0 U2a and Windows 2016. I also used the vSphere Web Client as you will see in the screenshots. I will […]
In this article we will show you how to enable SNMP on your VMware ESXi host, configure SNMP Community string and configure your ESXi firewall to allow or block access to the SNMP service from specific host(s) or network(s). Enabling SNMP service on a VMware ESXi host is considered mandatory in any production environment as it allows a Network Monitoring System (NMS) access and monitor the ESXi host(s) and obtain valuable information such as CPU, RAM and Storage usage, vmnic (network) utilization and much more. Furthermore, […]
Occasionally there is a need to patch an ESXi host without using Update Manager. It may be that Update Manager isn’t installed, or that there are network restrictions in place or that the host is standalone and not connected to vCenter. I recently had to patch such a host, so thought I’d run through the […]
