Scenario description
How many network interfaces can be connected to a VM?
Solution
Maximum number of network interfaces depends on the platform and vCPU on your VM. Here are the values for the platforms:
-
Broadwell (
standard-v1):- 2 to 16 vCPUs: 8 interfaces
- 20 to 32 vCPUs: 16 interfaces
-
Cascade Lake (
standard-v2):- 2 to 16 vCPUs: 8 interfaces
- 20 to 80 vCPUs: 16 interfaces
-
Ice Lake (
standard-v3):- 2 to 32 vCPUs: 8 interfaces
- 36 to 96 vCPUs: 16 interfaces
Note
When a VM starts, a maximum of 14 devices, including the boot disk and a NIC, can be connected to it. A VM will not start if it has more than 14 connected devices. Keep this in mind when creating the VM.
