Public bug reported:

Create VM on Microsoft Azure with size Standard_A8_v2 with 1 NIC.
After VM is running, shutdown VM.
Attach 7 NICs.
Start VM.

In some rate, some nics not get the IP,  /sys/class/net/eth7/operstate is down.
I saw the log in cloud-init, when it reads file /sys/class/net/eth7/operstate. If this file is written by kernel, then it is not a cloud-init issue, but kernel issue?
