Managing Parallels Server Bare Metal Network Creating a Virtual Network Virtual networks serve as binding interfaces between the virtual network adapters in virtual machines and Containers and the physical, VLAN, and virtual network adapters on the Parallels server. Using virtual networks, you can connect virtual machines and Containers to different networks. By default, Parallels Server Bare Metal creates the following virtual networks on the server: • Bridged. This virtual network is connected to one of the physical adapters on the Parallels server (as a rule, eth0) and provides virtual machines and Containers included in this virtual network with access to the network behind this physical adapter. • Host-only. This virtual network is connected to a special virtual adapter on the server and allows the virtual machines and Containers joined to this virtual network to access only the server and the other virtual machines and Containers on this network. You can also create your own virtual networks using the prlsrvctl or vznetcfg utility. For example, to make a new virtual network with the name of vznetwork1, you can rung one of the following commands: # vznetcfg net new vznetwork1 or # prlsrvctl net add vznetwork1 By default, both commands create host-only virtual networks. However, you can change their types using the prlsrvctl utility; see Configuring Virtual Network Parameters (p. 177) for details. In the current version of Parallels Server Bare Metal, you can create • Up to 16 host-only virtual networks. • One or more bridged virtual networks. The number of virtual networks depends on the number of physical and VLAN adapters available on the Parallels server. One virtual network can be connected to only one physical or VLAN adapter. Viewing Bridges A virtual network is associated with a bridge that is automatically made on the Parallels server when you create the virtual network and serves as the basis for the virtual network operation. To find out what bridge is associated with what virtual network, you can run the following command: # vznetcfg if list Name Type Network ID Addresses eth0 nic Bridged 10.31.252.116/16,fe80::2a9:40ff:fe0f:b6f2/64,dhcp br1 bridge Bridged fe80::200:ff:fe00:0/64 br0 bridge Host-Only 10.37.130.2/24,fdb2:2c26:f4e4::1/64,fe80::200:ff:fe00:0/64 The bridges existing on the Parallels server are listed in the Name column and can be easily identified by the br prefix. 176
Managing Parallels Server Bare Metal Network Note: Detailed information on the vznetcfg and prlsrvctl utilities is provided in the Parallels Server 5 Bare Metal Command Line Reference Guide. Configuring Virtual Network Parameters Parallels Server Bare Metal allows you to configure the following parameters for a virtual network: • the name assigned to the virtual network • the networking mode in which the virtual network is operating • the description of the virtual network All these operations can be performed using the prlsrvctl utility. Let us assume that you want to configure the psbmnet1 virtual network. This virtual network is currently configured as a hostonly network and has the following description set: This is a host-only virtual network. To change these parameters, you can execute the following command: # prlsrvctl net set vznetwork1 -n psbm_network1 -t bridged --ifname eth1 -d "This is now a bridged virtual network" This command configured the psbmnet1 virtual network as follows: 1 Changes the virtual network name to psbm_network1. 2 Changes the virtual network type to bridged. 3 Changes the virtual network description to the following: This is a now bridged virtual network. For more information on the prlsrvctl utility, refer to the Parallels Server 5 Bare Metal Command Line Reference Guide. 177
