VM到AHV中的VM网络故障排除

\u00a0The goal of this workflow is to walk-through troubleshooting VM to VM communication issues in a Nutanix Cluster. Most customers are very vague when they state they have a networking issue. We will go through painting a complete picture of the network topology by asking the right questions and running commands on the Hypervisors.<\/span><\/p>

Initial Triage:<\/u><\/strong><\/p>

Questions to Ask:\u00a0<\/strong><\/p>

• \t

  What hypervisor is running on the cluster?\u00a0<\/strong><\/p>\t<\/li>\t

• \t

  What guestOS is running on the VMs?<\/strong><\/p>\t<\/li>\t

• \t

  Are the VMs on the same node or different nodes?\u00a0<\/strong><\/p>\t<\/li>\t

• \t

  Are the VMs configured to use the same VLAN?\u00a0<\/strong><\/p>\t<\/li>\t

• \t

  What method is the customer using to test connectivity?\u00a0<\/strong><\/p>\t<\/li>\t

• \t

  Is there any Firewalls or ACLs that would stop this VM traffic?\u00a0<\/strong><\/p>\t<\/li><\/ul>
