The Overview page is the main management screen displayed when a client opens their Proxmox KVM service. It provides real-time VM status information, quick action buttons, and a complete network configuration summary.
Action Buttons
At the top of the page, action buttons allow the client to perform common operations:

Start — Power on the virtual machine

Stop — Gracefully shut down the virtual machine

noVNC — Open a browser-based VNC console session (see noVNC)

Charts — View performance usage graphs (see Charts)

Below the real-time information panel, additional management buttons provide access to:

Reinstall — Reinstall the operating system

Snapshots — Manage VM snapshots

Backups — Manage backups and schedules

Reset password — Reset the root/admin password

revDNS — Configure reverse DNS records

ISO — Mount or unmount ISO images

Firewall — Manage firewall policies and rules

The visibility of each button depends on the Client Area Permissions configured by the administrator for the product.
Information on Real Time
The overview displays live VM metrics that auto-refresh every 7 seconds:

Field
Description

Status
Current VM state (running / stopped) with uptime counter

CPU
Current CPU utilization percentage and number of allocated cores

RAM
Current memory usage with used/total values and a progress bar

System disk
System disk size with R/W throughput (MB/s) and IOPS limits

Additional disk
Additional disk size with R/W throughput (MB/s) and IOPS limits (if configured)

Network adapter
Network adapter model, MAC address, and link speed

Network Configuration
Below the real-time information panel, the network configuration section displays the complete networking setup for the VM:

IPv4 — Primary IPv4 address with subnet mask, plus any additional IPv4 addresses

GW — IPv4 gateway address

DNS — Configured DNS servers (primary and secondary)

IPv6 — Primary IPv6 address with prefix length, plus any additional IPv6 addresses

GW — IPv6 gateway address

Domain — The assigned domain name for the VM

An informational note reminds the client that only the main IP address is automatically configured on the network interface. Additional IP addresses must be configured manually inside the VM.

Disabled actions
When a feature is not permitted by the product's client-area permissions (or is temporarily unavailable — for example, during a backup or snapshot operation), the corresponding button stays visible but dimmed and is not clickable. This is intentional: the client can see the full list of features the product offers, even if specific ones are not allowed in their plan, and clearly understands the state of their VM while operations are in progress.

Changed in v3.0. Feature permissions have moved from the legacy configoption12 checkboxes to the new Bootstrap-based Client permissions panel in the product settings. All permission flags are preserved during upgrade, so the end-user behavior is identical to v2.x.

Navigation menu
Every sub-page in the client service area (Snapshots, Backups, Firewall, Reset password, revDNS, ISO, Charts, Reinstall) has a sidebar navigation menu that allows the client to jump between settings without going back to the overview each time.

If the client navigates directly to a page for a feature that the product does not allow, they see an Access Denied error message instead of the feature's UI. The Overview and noVNC buttons cannot be hidden — they are always available.
Error messages
The client area displays two common error messages:

Something went wrong — returned when WHMCS cannot reach the Proxmox server (network issue, credentials invalid, API service down) or when the VM is no longer present on Proxmox. Check the Log Collection chapter for diagnostics.

Access Denied — returned when the client tries to open a page (via a direct URL or a bookmarked link) for a feature that is not enabled for their product.
