Server virtualization, two ways

Run full KVM virtual machines and lightweight LXC containers side by side on the same host, managed from one interface.

  • ✓
    KVM — full virtualizationIndustry-standard Linux virtualization with near-native performance on Intel VT-x / AMD-V hardware. Run Windows and Linux VMs with fully isolated virtual hardware.
  • ✓
    LXC — container virtualizationOS-level containers that share the host kernel for a lightweight, fast-booting alternative to full VMs — ideal for app and service isolation.
  • ✓
    Debian GNU/Linux foundationBuilt on a custom Linux kernel with the source released under GNU AGPLv3 — fully inspectable, no black-box components.
  • ✓
    Mixed workloads on one hostConsolidate VMs and containers together to cut hardware costs while keeping the flexibility to choose the right virtualization type per workload.

Manage everything from one screen

A central web-based interface handles every task — no separate management server, no per-node juggling.

GUI

Web-based interface

An ExtJS-powered console gives you task history, system logs, backups, migrations, and HA activity across every node, from any browser.

📱

Mobile access

Manage VMs, containers, and clusters on the go via the Android app or the HTML5 mobile web client, with SPICE/HTML5 console access.

CLI

Command line interface

Full shell access with intelligent tab completion and man-page documentation for advanced administrators.

API

REST API

A fully documented JSON-Schema REST API lets KHCOLO automate provisioning and integrate Proxmox VE with your other tools.

⚑

Multi-master design

Manage your whole cluster from any node — there's no dedicated manager node required and no single point of failure for administration.

☰

Unified overview

See VMs, containers, storage, and cluster health at a glance, with drill-down into every task and log entry.

EXT.03

Clustering & high availability

Scale from a single node to a large clustered environment, with automatic failover built in from day one.

  • ✓
    Proxmox Cluster File System (pmxcfs)Real-time database-driven config sync across the cluster via Corosync — unique to Proxmox VE.
  • ✓
    Live / online migrationMove running VMs between cluster nodes with zero downtime, so maintenance never interrupts your users.
  • ✓
    HA Manager, zero configurationMonitors every VM and container and automatically restarts them elsewhere on node failure, using watchdog-based fencing.
  • ✓
    HA Simulator includedTest a 3-node, 6-VM failover scenario safely before relying on HA in production — KHCOLO runs this as part of every deployment.
EXT.04

Networking & storage that scales with you

From a simple bridged setup to VXLAN overlays and Ceph clusters — Proxmox VE's storage and network layer grows with your infrastructure.

  • ✓
    Software-Defined Networking (SDN)Isolated per-node networks up to complex overlays: VLANs, QinQ, VXLAN tunneling, and BGP-based EVPN across clusters and sites.
  • ✓
    Flexible storage modelMix local and shared storage with no artificial limits — configure as many storage targets as your workload needs.
  • ✓
    Ceph fully integratedRun and manage hyper-converged Ceph storage — RBD and CephFS — directly from the same GUI and CLI, scalable to the exabyte level.
  • ✓
    Distributed firewallCluster-wide or per-VM iptables-based rules, with macros, security groups, and full IPv4/IPv6 support.

EXT.05

Backup, restore, and Proxmox Backup Server integration

Full backups are built in, and Proxmox Backup Server plugs in natively for incremental, deduplicated, encrypted backups. KHCOLO deploys and manages both together.

↺

Scheduled backups

The integrated vzdump tool creates consistent snapshots of running VMs and containers on a schedule you set.

⚡

Live-restore

When paired with Proxmox Backup Server, a VM can start almost immediately while the rest of the data restores in the background.

📄

Single-file restore

Pull an individual file or folder out of a VM or container backup without restoring the whole guest.
