You use a predefined checkup to verify network connectivity and measure latency between two virtual machines (VMs) that are attached to a secondary network interface. The latency checkup uses the ping utility.
Verifies if the cluster storage is optimally configured for {VirtProductName}.

Before you run a latency checkup, you must first xref:../../virt/vm_networking/virt-connecting-vm-to-linux-bridge.adoc#virt-connecting-vm-to-linux-bridge[create a bridge interface] on the cluster nodes to connect the VM's secondary interface to any interface on the node. If you do not create a bridge interface, the VMs do not start and the job fails.
