-===== Virtual Host Configuration ===== 
-This page covers how to design and configure the **virtualization host** that underpins the Trash Panda Plex ecosystem.\\  
- 
-The virtual host is the control plane of the entire environment. If it is underpowered, misconfigured, or overcomplicated, every VM on top of it will inherit those problems. Conversely, a properly sized and segmented host largely disappears into the background — exactly what we want.\\  
- 
-This guide assumes:\\  
-  * The host OS is **Windows 11** 
-  * **VMware Workstation Pro 17** is used for virtualization 
-  * Three Ubuntu Server VMs will be deployed (Reverse Proxy, ARR Suite, Overseerr) 
-  * The broader network already supports **LAN, NFS, and DMZ VLANs** 
- 
-==== Design Priorities ==== 
-Before touching hardware or software, establish the priorities:\\  
- 
-1. **Stability Over Density**\\  
-The goal is not to pack the most VMs into the smallest box. It’s to run a few critical VMs reliably.\\  
- 
-2. **Predictable Performance**\\  
-Media automation is bursty. The host must absorb spikes without cascading failures.\\  
- 
-3. **Hard Network Separation**\\  
-VLAN separation must be enforced at the physical NIC level wherever possible.\\  
- 
-4. **Operational Simplicity**\\  
-Troubleshooting should start with clear boundaries, not guesswork.\\  
- 
- 
-==== Resource Sizing ==== 
-=== VM Resource Requirements (Baseline) === 
-The ecosystem requires **three Ubuntu VMs** with a combined minimum of:\\  
-  * **8 GB RAM total** 
-  * **6 vCPUs total** 
- 
-This is the **floor**, not the **ceiling**.\\  
- 
-=== Host Resource Considerations === 
-In addition to VM resources, the host must account for:\\  
-  * Windows 11 base OS overhead 
-  * VMware Workstation Pro services 
-  * Background and general-purpose workloads 
- 
-As a rule of thumb:\\  
-  * **CPU:** Choose a CPU with at least **2–4 physical cores beyond VM allocation**. High single-core performance matters more than core count. 
- 
-  * **Memory:** Add **8–12 GB RAM above VM requirements** to keep Windows and VMware responsive under load. 
- 
-  * **Storage:** Use fast SSD or NVMe storage for:\\  
-        * VM disks 
-        * Snapshot files 
-        * Logs 
- 
-Avoid placing VM disks on spinning media.\\  
- 
-==== Overcommitment Guidance ==== 
-VMware Workstation allows CPU and memory overcommitment, but this ecosystem benefits from restraint:\\  
-  * Light CPU overcommitment is acceptable 
-  * Memory overcommitment should be avoided 
- 
-Starving the host leads to unpredictable latency, which ARR services do not tolerate well. 
- 
- 
-==== Physical NIC Requirements ==== 
-The virtual host **must have three physical NICs**.\\  
- 
-Each NIC enforces a trust boundary.\\  
- 
-=== NIC Roles === 
-1. **Primary NIC (LAN / Default VLAN)** 
-  * Used by the host OS 
-  * Used by VMs that require LAN access 
-  * Carries management and general traffic 
- 
-2. **NFS NIC (Layer 2 Only)** 
-  * Dedicated to storage traffic 
-  * No host IP address 
-  * Used exclusively by VMs that mount NFS shares 
- 
-3. **DMZ NIC (Layer 2 Only)** 
-  * Dedicated to internet-facing services 
-  * No host IP address 
-  * Used exclusively by VMs in the DMZ VLAN 
- 
-These NICs should **not** be teamed or bonded. 
- 
- 
-==== Windows 11 Host NIC Configuration ==== 
-The goal on the Windows host is simple:\\  
-  * One NIC behaves like a normal network interface 
-  * Two NICs behave like invisible wires 
- 
-=== Primary NIC Configuration === 
-  * Assign IP via DHCP or static configuration as appropriate 
-  * Configure default gateway 
-  * Normal DNS configuration 
-  * This NIC handles: 
-        * Windows updates 
-        * VMware licensing 
-        * Management access 
- 
-=== NFS VLAN NIC Configuration === 
-  * **No IP address assigned** 
-  * No default gateway 
-  * Disable: 
-        * Client for Microsoft Networks 
-        * File and Printer Sharing 
-  * Leave the adapter enabled 
- 
-Windows should see this NIC as connected but unusable — that is intentional. 
- 
-=== DMZ VLAN NIC Configuration === 
-Configure identically to the NFS NIC:\\  
-  * No IP address 
-  * No gateway 
-  * No Windows networking services bound 
- 
-These NICs exist solely to be passed through to VMware virtual networks. 
- 
- 
-=== VMware Workstation Pro Networking === 
-VMware Workstation uses **Virtual Network Editors** to map physical NICs to virtual switches. 
- 
-=== Virtual Network Layout === 
-Create the following virtual networks:\\  
-  * **VMnet0 (Bridged – LAN)** 
-        * Bridged to Primary NIC 
- 
-  * **VMnet2 (Custom – NFS VLAN)** 
-        * Bridged to NFS NIC 
-        * No host connection 
- 
-  * **VMnet3 (Custom – DMZ VLAN)** 
-        * Bridged to DMZ NIC 
-        * No host connection 
- 
-Disable DHCP on VMnet2 and VMnet3. 
- 
-== Why This Matters == 
-  * VLAN tagging is handled by the physical network 
-  * VMware provides clean L2 handoff 
-  * The Windows host remains blind to NFS and DMZ traffic 
- 
-This significantly reduces accidental exposure and simplifies troubleshooting. 
- 
- 
-==== Storage Placement ==== 
-  * VM disks stored on fast local SSD/NVMe 
-  * Avoid snapshots as a long-term safety net 
-  * Snapshots are for: 
-        * Short-term changes 
-        * Known rollback points 
- 
-Snapshots are not backups. 
- 
- 
-==== Final Thoughts ==== 
-The virtual host is where **discipline pays off**.\\  
- 
-Clear resource headroom, hard NIC separation, and boring configurations produce:\\  
-  * Predictable VM behavior 
-  * Easier security reasoning 
-  * Faster recovery when something breaks 
- 
-If you’ve built the host correctly, the VMs on top of it become straightforward — and that’s exactly the outcome this ecosystem is designed to achieve.
