Networking

A network in Kyvernon is a host-bridge network: a bridge on each host, with an optional VLAN. With OVN logical networks switched on, a distributed port group is a segment that spans hosts. An IP pool holds the public addresses of one such network. Servers and virtual machines receive their public addresses from the pool, and the pool decides how long a released address stays in quarantine.

Networking concepts explains networks, VLANs, port security and how a public address reaches a virtual machine. Host-bridge networks creates and changes the networks. Then IP pools creates the pools. Public addresses describes how an address is assigned to a server, Reverse DNS how its name is set, and Traffic how the monthly traffic of a server is counted and limited. Networking troubleshooting lists symptoms and remedies. The distributed firewall filters the traffic of each network adapter; its tasks are in Distributed firewall.

• Networking conceptsHost-bridge networks, VLANs, port security, quarantine networks, OVN segments and how a public address reaches a virtual machine.
• Host-bridge networksCreate, edit and delete a host-bridge network in the console: VLAN, hosts, DHCP, MTU, lease time, domain, uplink mode, port security and policy.
• Distributed switches and port groupsCreate distributed switches with host uplinks and port groups with a VLAN or overlay, addresses, DHCP and fixed addresses, realised as OVN segments.
• IP poolsCreate, change and delete IP pools of public addresses in the console and see free addresses, allocations, quarantine and reverse DNS requests.
• Public addressesAssign and release the public addresses of a server in the console, add a public network card when you create it, and allow outgoing mail.
• Reverse DNSSet the reverse DNS name of a public address in the console, automatically through PowerDNS or by request to the provider.
• TrafficRead the monthly traffic of a server in the console and set its limit, the action at the limit and traffic packages.
• Distributed firewallThe firewall of virtual machines, enforced at each network adapter on the host: concepts, tasks for administrators and tenants, and reference.
