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@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
best
Adrian
