Thanks for the bug Gauthier.
This issue is due to older 4.4 FIPS kernel not exposing a master
attribute in /sys/class/net/<devname> for SRIOV advanced networking
devices. Cloud-init is able to ignore this device file on Xenial's newer
4.15.0-1114-azure kernel on Azure, but I'm afraid we won't be able to
either manipulate the 4.4 certified FIPS kernel to expose this 'master'
sysfs device file
on FIPS kernel 4.4.0-1017-fips Xenial no "master" sysfs attribute
allowing cloud-init to determine SRIOV device.
