Virtualizor VPC architecture: subnets, gateway, security groups, VXLAN overlay, NAT and peering
In one picture

Subnets, overlay and optional controls

One VPC object: isolated CIDR, subnets with attached VMs, OVS/VXLAN across nodes that need it, and NAT, security groups or peering only when you turn them on.

  • VPC-A with Subnet A/B and guest private IPs
  • OVS bridge + VXLAN mesh across participating nodes
  • Optional NAT gateway for outbound internet
  • Optional peering to VPC-B in another server group
How it works

From VPC create to private VM traffic

One feature, one flow. Virtualizor creates the private network objects and the overlay so you do not hand-build tunnels for every host.

Create VPC + subnets

Set name, CIDR, gateway and DNS. Bind to a server group. Add subnets with IP windows. Virtualizor creates the OVS bridge on the primary node.

Attach VMs, any node

Attach a VPS to a subnet at create time or from manage VPS. Guests get a private IP. Any node in the server group can join the overlay automatically.

Add controls if needed

Enable a NAT gateway for outbound internet, security groups for in/out rules, or peering to another VPC in a different server group.

Core capabilities

What a Virtualizor VPC actually gives you

Three parts, one object. No separate products to license or wire together.

VPC with Subnet A and Subnet B, gateways and attached VMs

Subnets & attach

Subnets sit inside the VPC CIDR with their own gateway and IP window. Attach guests at create time or later from manage VPS - VLAN tags are assigned automatically.

  • Subnet must fit the parent CIDR, no overlaps
  • First / last IP window for allocation
  • Can't delete a subnet while VMs are attached
Multi-node OVS bridges meshed with VXLAN inside a server group VPC

Multi-node overlay

When a VM on another node needs the VPC, Virtualizor ensures that node has the bridge and builds VXLAN tunnels to peer nodes - on demand, not pre-provisioned everywhere.

  • Same OVS bridge on every participating host
  • VXLAN mesh keyed to the VPC's VNI
  • Overlay stays inside the VPC's server group
Optional VPC controls: NAT gateway, security group and peering to VPC-B

NAT, security groups & peering

Private by default. Turn on only what the workload needs - outbound internet, filtered traffic, or a link to a VPC in a different server group.

  • NAT gateway: outbound via a public IP, bandwidth tracked
  • Security groups: in/out rules by protocol, port, CIDR
  • Peering links different server groups only

Virtualizor VPC feature specifications

Technical details of Virtualizor's built-in private cloud SDN engine.

Status Feature / Component Capability & Technical Detail
Subnets & CIDR Isolated CIDR blocks (/16 to /28) with custom gateways, DNS, and allocation windows.
Multi-Node Overlay Automatic Open vSwitch (OVS) bridge creation and VXLAN encapsulation keyed by VNI.
NAT Gateway Outbound internet access via dedicated public IP with real-time bandwidth metering.
Security Groups Stateful firewall rules filtering TCP, UDP, ICMP traffic by port and IP range.
VPC Peering Encrypted private cross-server group interconnects without public routing.
Hot-Plug Attach Dynamically attach or detach VMs to subnets without rebooting host nodes.

Virtualization types with VPC support

Only stacks that implement VPC support are offered when you create a VPC.

Who does what

Admin power, Cloud self-service

What each role can do matches the shipped panel.

Administrators

  • Create, edit and delete any VPC; set owner and server group
  • Manage subnets, NAT gateways, security groups and peering
  • Assign security groups to VPC-attached VPS
  • Admin API for automation

Cloud users

  • VPC UI is for Cloud user type (not every VPS-only client)
  • Own VPCs only: create, edit, delete within quotas
  • Own subnets; attach and detach on their VPS
  • Peering for their VPCs; enduser API for the same scope

IP pools, VPS firewall plans and PowerDNS are separate networking tools - not part of the VPC object itself.
