Comment 5 for bug 1766300

According to this MS Documentation:
https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/integration-services

The hv_fcopy_daemon have a low impact on VM.
The role of this daemon isn't necessary to a Azure VM, as you will not use it to copy files from/to VM (This could be necessary if you are directly on Hyper-V Console )

Looking into debian sources:
https://sources.debian.org/src/linux/5.0.2-1~exp1/debian/hyperv-daemons.hv-fcopy-daemon.service/

You will see that a different condition exist to run this service daemon:
ConditionPathExists=/dev/vmbus/hv_fcopy

So just add this extra condition to ubuntu service description on
/lib/systemd/system/hv-fcopy-daemon.service

Restart your VM and you will see it is no more degraded.
