Virtual Networks

Virtual Networks connect your Virtual Machines to the host's networking infrastructure.

Creating a Virtual Network

1. Navigate to Virtualization > Networks.
2. Click Create Network.
3. You will define how the virtual network bridges to the physical world:
   • Bridged: Connects directly to an existing Linux Bridge on the host. VMs on this network act as if they are physically plugged into that bridge.
   • OVS: Connects to an existing Open vSwitch bridge.
   • NAT / Isolated: (If configured) Creates an internal network solely for VMs, optionally routing traffic out through the host's IP via NAT.

Portgroups

For OVS networks, you can define Portgroups. Portgroups allow you to apply specific configurations (like VLAN tags or bandwidth limits) to a group of virtual interfaces. When creating a VM, you can assign its interface to a specific Portgroup rather than just the network itself.

DHCP Leases

If your virtual network is configured to provide DHCP (e.g., an isolated network with a built-in DHCP server), Vapor allows you to view the active DHCP leases.

• Navigate to the specific Virtual Network.
• Click the DHCP Leases tab to see which IP addresses have been assigned to which VM MAC addresses.
