When deploying systems in a VMware ESXi virtualization environment, you may encounter several challenges. Here’s a quick guide to troubleshooting common issues to ensure a smoother installation process.
- Unable to Install 64-bit Operating System: Ensure that Intel Virtualization Technology is enabled in the BIOS settings, which is essential for running 64-bit operating systems.
- Setting Up Virtual Network Cards: Create virtual network cards based on the IP address range identified by ESXi. After adding a new network card, check its connection information to identify the corresponding switch. For both Windows and Linux systems, use either the reconnect method or match the MAC address (using
ifconfigfor Linux) to properly configure network interfaces. Typically, the naming order of network cards remains consistent between the guest OS and ESXi. - Disabling Hyperthreading: For DL380 series servers G8 and above that support hyperthreading, disable it by navigating to System Options => Processor Options => Intel® Hyperthreading Options => Disabled.
- RAID Configuration: Before installation, use disk array management tools to create a Logical Drive (RAID 1+0 recommended). Enable Write-Cache Battery Override in Cache Settings for performance optimization.
These tips can effectively resolve common issues encountered when installing virtual machines on VMware ESXi, making the setup of your virtual environment quicker and more efficient.
