Whether the Virtual desktop dont need network connection with HCI and VDC ?

Since I see below
8866 → Agent VM communication

I believe the virtual desktop itself doesn't need to talk directly to the HCI or the VDC for most of its work. The VDI Agent VM is the one that keeps the communication link with the VDC, usually over port 8866. The end-user virtual desktops connect through the agent and broker services, not directly to the HCI or VDC management layer. The desktop's network is mainly for user traffic (apps, internet, file shares, etc.), while the agent handles the management/control plane with VDC. So yes, the virtual desktops don't directly connect to HCI/VDC, the agent VM is the middle layer that handles this part.

Is this answer helpful?

The virtual desktop itself, in my opinion, is capable of handling most tasks without direct interaction with the VDC or the HCI.  The VDI Agent VM maintains the communication connection with the VDC, usually over port 8866.  The end-user virtual desktops use the agent and broker services rather than establishing a direct connection to the HCI or VDC management layer.  The desktop network is mostly utilized for user traffic (file shares, apps, the internet, etc.), while the agent uses VDC to operate the management/control plane.  Since virtual desktops don't connect directly to HCI/VDC, the agent virtual machine (VM) is the intermediary layer that controls this feature.

Even though port 8866 is used for Agent-to-VM communication between the VDC and virtual desktops, the virtual desktops still require network connectivity with both the HCI and the VDC because based on my understanding though I'm not that expert in terms of VDI Deployment, Port 8866 enables management communication (commands, monitoring) between the VDC and the desktop agents, but this communication happens over the network. Virtual desktops run on the HCI hosts, so they still need network access to storage, compute resources, and other infrastructure services. The VDC manages desktop provisioning, user authentication, and session control, all of which require network connectivity. In short, port 8866 is part of the network communication—but the underlying network connection itself between virtual desktops, HCI, and VDC is still necessary for the VDI environment to work correctly.

Please feel free to correct me if any part of my understanding is inaccurate.

I think the majority of the work done by the virtual desktop itself can be done without direct communication with the HCI or the VDC.  The communication relationship with the VDC is maintained by the VDI Agent VM, often over port 8866.  Instead of connecting directly to the HCI or VDC administration layer, the end-user virtual desktops employ the agent and broker services.  The agent manages the management/control plane using VDC, whereas the desktop network is mostly used for user traffic (apps, internet, file shares, etc.).  Therefore, the agent virtual machine (VM) is the intermediary layer that manages this aspect; the virtual desktops do not connect directly to HCI/VDC.
