How the Platform Updates Boot Order
|
||
</p>
|
||
<div class="bg-background-secondary/60 p-3 rounded text-xs text-base/80 space-y-2">
|
||
<p>The control panel translates your boot order selections into the same parameters Proxmox expects (for example, <code>scsi0</code> for the primary disk, <code>ide2</code> for a virtual CD/DVD, and <code>net0</code> for PXE). When you save, the backend updates the VM configuration on the node so the hypervisor knows which device to start from first.</p>
|
||
<p>Legacy BIOS-style flags such as <code>order=dc</code> are mapped automatically, and storage mappings are inferred from the datastore you chose—local-LVM disks become SCSI devices, ISO images are attached as virtual IDE drives, and network boot entries map to the network adapters listed in the UI.</p>

|

<div class="bg-background-secondary/60 p-3 rounded text-xs text-base/80 space-y-2">
|
||
<p>Use the “Console” tab or the node’s shell tools to inspect QEMU devices. Commands like <code>qm monitor <vmid> info block</code> or <code>qm config <vmid></code> show which disks are attached and the current boot priorities.</p>
|
||
<p>For UEFI guests, enabling OVMF debugging or attaching a serial console can capture early boot logs. The platform exposes toggles for these options so you don’t have to edit config files manually.</p>
|
||
<p>Whenever you open the web console, the panel requests a one-time VNC/WebSocket tunnel from the hypervisor. This lets you troubleshoot boot issues immediately without handling node credentials yourself.</p>

How Network Settings Are Applied
|
||
</p>
|
||
<div class="bg-background-secondary/60 p-3 rounded text-xs text-base/80 space-y-2">
|
||
<p>The Network tab mirrors the bridge definitions on each Proxmox node (for example, <code>vmbr0</code> for the public network). When you attach a NIC in the UI, the backend writes the same <code>net0=...</code> syntax that Proxmox uses, including MAC address, bridge, firewall flag, VLAN tag, and rate limits.</p>
|
||
<p>This means any change you make—adding a VirtIO adapter, toggling the firewall, or tagging a VLAN—is propagated down to the node in the exact format it expects, ensuring the guest receives the configuration you see on screen.</p>

|
||
<div class="bg-background-secondary/60 p-3 rounded text-xs text-base/80 space-y-2">
|
||
<p>Use standard Linux networking tools on the node, such as <code>ip link show type tap</code> to inspect TAP interfaces, <code>tcpdump -i vmbr0</code> to watch bridge traffic, and <code>bridge fdb show</code> to view MAC tables.</p>
|
||
<p>Inside the hypervisor shell, <code>qm config <vmid></code> lists the virtual NICs (net0, net1, etc.) exactly as the platform created them. You can also open a QEMU monitor session (<code>qm monitor <vmid></code>) and run <code>info network</code> for deeper diagnostics.</p>
|
||
<p>If you suspect bridge or firewall issues, <code>brctl show vmbr0</code>, <code>bridge vlan show</code>, and filtering <code>iptables -L</code> output by bridge name are quick ways to confirm whether packets are being forwarded.</p>

Platform Firewall Integration

</h3>
|

<div class="bg-background border border-neutral rounded-md p-4 mb-4">

<p class="text-sm text-base/70 mb-2">
|

The management platform includes an integrated firewall system that can apply rules at the VM level, bridge level, or cluster level.
|
||
</p>
|
||
<div class="bg-background-secondary/60 p-3 rounded text-xs text-base/80 space-y-2">
|
||
<p>Toggling the firewall slider on a NIC tells the backend to recreate that interface definition with the firewall flag enabled. Any rules you define in the UI (direction, action, CIDRs, ports, comments) are stored centrally and rendered to iptables on the node, so you don’t have to craft rule syntax yourself.</p>
|
||
<p>The platform automatically maps rules to the correct chains—INPUT for traffic hitting the node, FORWARD for VM-to-VM flows, and OUTPUT for traffic originating from the VM—keeping your policy consistent across the cluster.</p>

<p>Changing the display adapter in the UI instructs the backend to update the VM’s <code>vga</code> parameter to VirtIO, Standard VGA, VMware SVGA, QXL, or “none” for headless guests. Selecting “Serial console” rewires the console tab to a text-only TTY.</p>
|
||
<p>When you adjust video memory, the platform recalculates the amount of VRAM allocated from system RAM (16–256 MB for VirtIO-GPU) and pushes that value to the node. Disabling the memory balloon when large VRAM is requested prevents the guest from losing addressable space.</p>

Network and Disk I/O Values
|
||
</h4>
|
||
<p class="text-sm text-base/70">
|
||
Network In/Out and Disk I/O values displayed in the statistics table represent the <strong>difference</strong> between the current statistic and the previous one. This shows the amount of data transferred or disk operations performed during the time period between statistics. The rate (bytes/s) is calculated based on the time difference between statistics.

Automatic statistics are maintained at a maximum of 24 entries per server. When this limit is reached, the oldest automatic statistic is automatically removed when a new one is created. Manual statistics are separate and can be individually deleted. This ensures you always have the most recent 24 hours of automatic performance data while allowing flexibility for manual snapshots.

Statistics Collection for All VPS
|

</h4>
|

<p class="text-sm text-base/70">

Statistics are collected for all virtual machines regardless of their power state (running, stopped, suspended) or service status. This ensures you have a complete historical record of your server's state and can track performance even when the VM is not actively running. Some metrics (like CPU usage) will be zero or minimal when the VM is stopped, but the data point is still valuable for historical tracking.

Border Gateway Protocol (BGP) is the routing protocol that makes the internet work. This guide explains how BGP works and how to get started with BIRD2, a popular open-source BGP implementation.

<div class="bg-background border border-neutral rounded-md p-4 mb-4">

<p class="text-sm text-base/70 mb-2">
|
||
BGP (Border Gateway Protocol) is an exterior gateway routing protocol (RFC 4271) used to exchange routing information between autonomous systems (AS) on the internet. Unlike interior gateway protocols like OSPF or RIP, BGP is designed for routing between different organizations and networks.
|
||
</p>
|
||
<ul class="text-sm text-base/70 list-disc list-inside space-y-1 mb-2">
|
||
<li><strong>Autonomous System (AS):</strong> A collection of IP networks under a single administrative control, identified by a unique AS number (ASN)</li>
|
||
<li><strong>Path Vector Protocol:</strong> BGP maintains not just routes, but the entire path (AS path) to reach destinations</li>
|
||
<li><strong>TCP-based:</strong> Uses TCP port 179 for reliable communication between BGP peers</li>
|
||
<li><strong>Policy-based:</strong> Routes are selected and filtered based on configurable policies</li>
|
||

BGP Session Establishment
|
||
</p>
|
||
<p class="text-sm text-base/70 mb-2">
|
||
BGP operates through sessions between routers (BGP speakers). The process involves:
|
||
</p>
|
||
<ol class="text-sm text-base/70 list-decimal list-inside space-y-1 mb-2">
|
||
<li><strong>TCP Connection:</strong> BGP peers establish a TCP connection on port 179</li>
|
||
<li><strong>OPEN Message:</strong> Exchange BGP capabilities, AS numbers, and hold timers</li>
|
||
<li><strong>UPDATE Messages:</strong> Exchange routing information (prefixes, attributes)</li>
|
||
<li><strong>KEEPALIVE Messages:</strong> Maintain session (sent every 30 seconds by default)</li>
|
||
<li><strong>NOTIFICATION Messages:</strong> Error handling and session termination</li>
|
||
</ol>
|
||
<pre class="bg-background-secondary p-3 rounded text-xs overflow-x-auto"><code># BGP Message Types (RFC 4271)
|
||
# 1. OPEN - Initial session negotiation
|

# 2. UPDATE - Route advertisements/withdrawals

|
||
# 4. KEEPALIVE - Session maintenance
|

# BGP Finite State Machine:

# Session States:
|

# - Idle: Initial state, no connection
|
||
# - Connect: TCP connection attempt
|
||
# - Active: TCP connection failed, retrying

BGP Route Selection Process
|
||
</p>
|
||
<p class="text-sm text-base/70 mb-2">
|

When multiple paths exist to a destination, BGP uses a decision process to select the best route:
|
||
</p>
|
||
<ol class="text-sm text-base/70 list-decimal list-inside space-y-1 mb-2">
|
||
<li><strong>Valid Next-Hop:</strong> Next-hop must be reachable</li>
|
||
<li><strong>Highest Local Preference:</strong> Administrative preference (default: 100)</li>
|
||
<li><strong>Shortest AS Path:</strong> Fewer AS hops preferred</li>
|
||
<li><strong>Lowest Origin Type:</strong> IGP < EGP < Incomplete</li>
|
||
<li><strong>Lowest MED (Multi-Exit Discriminator):</strong> Prefer lower MED values</li>
|
||
<li><strong>eBGP over iBGP:</strong> External routes preferred over internal</li>
|
||
<li><strong>Lowest IGP Metric:</strong> Shortest path to BGP next-hop</li>
|
||
<li><strong>Oldest Route:</strong> Prefer route received first</li>
|
||
<li><strong>Lowest Router ID:</strong> Tie-breaker using BGP router ID</li>
|
||
<li><strong>Shortest Cluster List:</strong> For route reflectors</li>
|
||
<li><strong>Lowest Neighbor Address:</strong> Final tie-breaker</li>

BGP is the protocol that makes the internet work by routing traffic between ISPs and large networks. Operates on TCP port 179. BGP uses path vector routing, maintaining a table of network reachability information along with the path (AS path) to reach those networks. Key features include: AS path attributes for loop prevention, route selection based on multiple criteria (local preference, AS path length, origin, MED), support for IPv4 (BGP-4) and IPv6 (MP-BGP), route reflectors and confederations for scaling, and communities for policy control. BGP sessions can be internal (iBGP) within an AS or external (eBGP) between ASes. Used extensively in data centers, cloud providers, and internet backbone routing. Supports route filtering, prefix limits, and graceful restart for high availability.</dd>

Major IXPs include AMS-IX (Amsterdam), DE-CIX (Frankfurt), LINX (London), and Equinix. IXPs typically use Ethernet switches (Layer 2) with participants connecting via 1G, 10G, 100G, or higher speed ports. They facilitate both public peering (via shared switch fabric) and private peering (direct cross-connects). IXPs use BGP for route exchange and often provide route servers to simplify peering. Benefits include: reduced latency (local traffic stays local), cost savings (avoiding transit fees), improved redundancy (multiple paths), and better performance (direct interconnections). IXPs are critical infrastructure for internet routing efficiency and are often non-profit organizations managed by their participants.</dd>
