I have seen several people asking about default vNIC speed on Nutanix AHV. When you create vNIC via Prism, default vNIC speed is 10Gbps. However you can create vNIC with lower speed too, if you want. This task is available only via acli command line.
Log in to CVM over ssh and get into acli. From acli run,
vm.nic_create <VM_NAME> model=e1000 network=<portgroup_name>
<acropolis> vm.nic_create TestVM01-0 model=e1000 network=VLAN92 NicCreate: complete
Check, if vNIC is showing up on VM config;
vm.nic_get <VM_Name>
<acropolis> vm.nic_get TestVM01-0 } 50:6b:8d:18:99:49 { mac_addr: "50:6b:8d:18:99:49" model: "e1000" network_name: "VLAN92" network_uuid: "8e06c992-7543-48f7-9380-51493b09317b" type: "kNormalNic" } <acropolis>
One more verification, this time on guest OS.
