3.1. Host networking

On the data link layer (layer 2), RHV enables the configuration of Linux bonds to connect to VLANs and define the MTU for network interfaces. These networks can be shared via Linux bridges to virtual machines.

For SR-IOV, you can configure the number of virtual functions and their mapping to logical networks.

FCoE manages its own VLANs. These FCoE managed VLANs are used exclusively for storage access. They are invisible to the Manager and any virtual machines.

iSCSI manages iSCSI bonds. They are not part of RHV’s visible host network configuration. You can use iSCSI without iSCSI bonds, which are useful only to improve the reliability of iSCSI storage.

Important

All hosts in a cluster must use either IPv4 or IPv6 as the IP stack for their management network. Dual stack is not supported.

You can configure the DNS resolver that the host uses.

It is also possible to manage network roles and QoS.
