CentOS - Jan 2017 - Centos 7 as a Hyper-V guest and Integration Services

Dear all

I'm running a Centos 7.3 as a Hyper-V guest on Windows Server 2012R2.
Actually everything works fine but I'm still wondering if I do everything
right regarding Linux Integration Services.

When I installed Centos 7 I didn't installed any LIS package or so as I
understood it's built-in.
How are you handling this?
Is it recommended to install/update to the latest LIS from Microsoft provided as
ISO or do I need to install the hyperv-daemons?


Currently my system reports:
[root at share ~]# lsmod | grep hv
hv_utils               24418  2
hv_storvsc             18032  6
hv_netvsc              40261  0
hv_vmbus              397185  6
hyperv_keyboard,hv_netvsc,hid_hyperv,hv_utils,hyperv_fb,hv_storvsc

and I think this time shifts on rebbots are related to missing LIS (?):

Do you also get this Warnings in Hyper-V Event Viewer?:

Device 'Microsoft Synthetic Display Controller' in 'SHARE' is
loaded but has a different version from the server.  Server version 3.3 Client
version 3.2 (Virtual machine ID C2D0C208-BC00-4E73-8AF1-DA595FE6ECE7). The
device will work, but this is an unsupported configuration. This means that
technical support will not be provided until this problem is resolved. To fix
this problem, upgrade the integration services. To upgrade, connect to the
virtual machine and select Insert Integration Services Setup Disk from the
Action menu.


Thanks
