Does Horion for Linux supports 3D acceleration like those in Windows? In Win7 pool setting, I can find at least a "3D Renderer" option. However there is no such option in Linux pool setting. If yes, can advise any documentation on it? Thanks.
Yes it does, you can use vSGA, vDGA, vGPU on RHEL. For vDGA (pass-through) you'll need a compatible NVIDIA card and you will need to configure it as a shared PCI device on the vSphere host. For vSGA or vGPU you will also need to prepare the vSphere host and install the NVIDIA driver. The following links should help:
