5.1. Managing Network Adapters on the Hardware Node

Network adapters installed on the hardware node are used to provide virtual machines and containers with access to each other and to external networks. During the installation, Virtuozzo registers all physical network adapters available on the server. Once Virtuozzo has been successfully installed, you can manage network adapters on the hardware node using native RHEL7 utilities. You can also create bond and VLAN interfaces (for example, with the nmtui tool) and use them instead of physical ones.

Important

  1. Each network adapter must have only one configuration file in the /etc/sysconfig/network-scripts/ directory.
  2. When you need to apply changes to network settings, use systemctl restart NetworkManager.service instead of systemctl restart network. The latter command may result in issues with both bridged and routed networks.
