HiHi,

Without vmTools, many advanced features and optimizations become unavailable or limited. These include CPU and memory hot add, hot expansion of IDE disks, power-on expansion, accurate performance monitoring, virtio driver support, and better IP address management. The maximum supported single disk size is also limited to 2TB without vmTools.

In summary, while VMs can run without vmTools in HCI, it is strongly recommended to install vmTools to enable full functionality, better performance, and advanced management features.
