About Horizon Agent running in native Microsoft Azure VMs
Running Horizon Agent in virtual machines on native Microsoft Azure has the following limitations:
- Horizon Agent installation in Desktop mode is not supported on Windows Server OS.
- Windows 10 and Windows 11 multi-session VMs cannot provide both a desktop pool and application pool from the same host. This means that for the use case where you want to provide both a desktop pool and application pool, you'll need two (2) multi-session VMs: one VM to use for the desktop pool and one VM for the application pool.
- For H264, HEVC, and AV1 decoding, Horizon supports the hardware encoding protocols that are available on the underlying GPU.
