Forgot the vcf or root password on SDDC Manager? This guide walks through using GRUB single-user mode in Photon OS to unlock accounts, reset passwords, and quickly restore SSH access so your VMware Cloud Foundation environment stays operational and secure.
Not sure whether your network card is supported by ESXi? This step-by-step guide shows how to check the official compatibility list, filter NIC models, and confirm required drivers and firmware so you can avoid installation issues and keep your virtualization environment stable.
After deploying ESXi 8.0 on a Dell R760, you may see a TPM 2.0 connection warning even though the hardware is healthy. This guide explains the real cause — an unsupported SHA1 hashing algorithm — and walks through checking logs, updating TPM to SHA256, and clearing the alert safely in Maintenance Mode.
Logs are essential for diagnosing and troubleshooting issues in VMware ESXi environments. Whether you’re facing host performance problems, VM crashes, or storage connection failures, collecting a complete log bundle is the first step. This guide walks you through three reliable methods—via vSphere Client, ESXi Host Client, and command line—to quickly gather the necessary logs for analysis.
In virtualization management, VMware Workstation and ESXi are commonly used platforms. Many IT operations teams need to migrate VMs between these two environments—for example, for
Configure vSwitch link aggregation and failover quickly using esxcli commands for flexible, scriptable network management.
Assign Active, Standby, and Unused uplinks and add NICs to vSwitches without the GUI.
Ensure high availability and optimized performance across your ESXi hosts.
Discover whether you can vMotion VMs between ESXi 6.7, 7.0, and 8.0 hosts without interruption.
Explore the key hardware and CPU requirements, EVC mode setup, and vCenter version guidelines.
Get practical tips for seamless, cross‑version migrations.
Sometimes, a VM becomes unreachable due to network issues, leaving the ESXi host as the only point of access. In such cases, knowing how to retrieve files via SSH from ESXi can be a crucial skill for VMware administrators.
Encountering a situation where all virtual machine disks in vCenter show 0GB and options are greyed out? This issue often stems from an SSL certificate mismatch. In this guide, we walk you through diagnosing the problem and fixing it using VMware’s lsdocter script.
Sometimes, a virtual machine in ESXi may become unresponsive due to snapshot operations, high disk usage, or other issues. When traditional shutdown methods in vCenter or the ESXi web interface fail, using command-line tools like esxcli and vim-cmd can help forcefully shut down the VM.
