Introduction Logs play a pivotal role in the management and troubleshooting of IT environments. Aria for Logs (formerly known as vRealize Log Insight) provides powerful log management capabilities, enabling deep analytical insights and real-time monitoring of data from various sources, including vSphere. To ensure Aria for Logs effectively collects and analyzes log data, it requires specific permissions within your vCenter Server. This blog post will guide you through creating a custom role in vCenter tailored for the Aria for Logs service account. ...

In the evolving landscape of VMware ESXi environments, maintaining compatibility and ensuring that systems adhere to specific boot requirements is essential. As more environments transition towards UEFI, there might still be a need to check or enforce legacy BIOS boot methods on certain ESXi servers, especially for compatibility with older hardware or specific operational requirements. This blog post will guide VMware administrators on how to automate the process of checking the boot option (UEFI or Legacy BIOS) on multiple ESXi hosts using PowerShell and Plink. ...

In today’s dynamic IT environments, maintaining a secure and efficient infrastructure is paramount. For VMware vSphere administrators, managing the firewall settings on vCenter servers is a critical task that ensures the security of the entire virtualized infrastructure. Ansible, an open-source automation tool, offers a streamlined approach to managing firewall settings across multiple vCenter servers. This blog post will guide you through automating vCenter server firewall configurations using Ansible, showcasing how to apply these changes across multiple servers seamlessly. ...

In the realm of VMware vSphere management, securing your vCenter Server is critical to maintaining a robust and secure infrastructure. SaltStack Config, integrated into VMware’s vRealize Automation suite, offers a powerful way to automate and manage configurations across your VMware environment, including firewall settings. This blog explores how to leverage SaltStack Config to automate firewall adjustments on your vCenter servers, ensuring consistent security policies and simplifying the process across multiple instances. ...

VMware PowerCLI can manage the firewall exceptions on ESXi hosts through vCenter Server. The commands in this guide change the SSH Server firewall exception on ESXi; they do not configure the firewall of the vCenter Server Appliance (VCSA). Enabling this exception permits inbound SSH traffic through an ESXi host’s firewall. It does not start the SSH service. Opening SSH on many hosts also increases the management-plane attack surface, so target only the hosts that require access and disable the exception as soon as the work is complete. ...

As I was installing\upgrading my lab environment to ESXi 7.0 I received an error that the CPU was unsupported. As per the release notes vSphere 8.0 release notes my CPU is no longer on the compatibility list. Since this is a lab environment I wanted to continue using my current hardware. It goes without saying that this method should not be used in a production environment. To allow the legacy CPU all I had to do is boot up from the ISO, on the boot Menu I pressed TAB or Shift + O and added allowLegacyCPU=True option as seen in the screenshot below ...

Migrating virtual machines (VMs) from a cloud environment to an on-premises VMware vSphere infrastructure can be a daunting task. However, with the right tools and processes in place, it can be a seamless and efficient process. One such tool is the VMware Converter, which enables users to convert native cloud VMs\physical servers to vSphere machines. In this blog post, we will discuss the benefits and challenges of converting cloud VMs and provide a step-by-step guide for using VMware Converter to achieve this goal. ...

Important safety update (August 25, 2026): Do not manually remove NSX VIBs with esxcli software vib remove. Broadcom documents that this method is unsupported and can cause loss of management or workload networking. The executable removal guidance previously shown on this page has been removed. Use the current follow-up instead: Safely Removing Stale NSX VIBs from an ESXi Host. It starts with the NSX Manager removal workflow and covers the narrower stale-package condition where Broadcom directs administrators to use nsxcli -c del nsx while the host is in maintenance mode. ...

VMware vRealize Operations (vROps) is a comprehensive solution for managing the performance and capacity of virtual environments. It offers several workload optimizations to help administrators balance resource utilization, meet SLAs, and ensure optimal performance. These optimizations go beyond what is possible with traditional Distributed Resource Scheduler (DRS) and can provide numerous benefits to organizations. In this blog, we will explore some of the advantages of using vROps workload optimizations over regular DRS. ...

VMware vRealize Automation (vRA) and Puppet address different parts of infrastructure management. This comparison looks at VMware integration, cloud management, automation, self-service, and cost before outlining where vRA fits. Where vRA Outshines Puppet Integrated Management: vRA integrates with VMware’s vSphere virtualization platform, allowing for a seamless management of virtual machines (VMs). With Puppet, you would need to use additional tools to manage your virtual environment. Cloud Management: vRA is capable of managing both on-premise and cloud infrastructure, making it an ideal solution for hybrid cloud environments. Puppet, on the other hand, is primarily focused on on-premise deployments. Automation: Automation is at the core of both vRA and Puppet. However, vRA provides a more comprehensive automation solution with its built-in workflows and drag-and-drop design. This makes it easier for users to automate their infrastructure without having to write complex code. Self-Service: vRA provides a self-service portal for users to request and manage their own resources, reducing the burden on IT. Puppet does not have this capability, making it a less attractive option for organizations looking to implement a self-service model. Cost: vRA is a commercial product and is typically more expensive than Puppet. However, the added features and integration with other VMware products make it a more cost-effective solution in the long run. The Verdict vRealize Automation fits teams that need VMware-aware provisioning, hybrid-cloud management, and a self-service catalog. Puppet may be the better fit when configuration management is the main requirement or licensing cost is the deciding factor. ...
