CentOS 7 using old version of Linux Integration Services
-
Here is Microsoft's official grid for LIS support.

So because It seems the native is supposed to support Server 2016 core, then how come I cannot make a snapshot.
-
If I shut down the VM, I can make checkpoints and backups with no errors.
This is also happening on a fully updated Server 2012 R2 DataCenter + Hyper-V system.

I'm running some CentOS 7 proxy servers. One of them is running on Server 2012 R2 DataCenter + Hyper-V as well.
Backups via Windows Server Backup and checkpoints work just fine while the machine is running.Here's what mine shows... not exactly the same as yours, but may be some help? I don't mind taking a checkpoint and updating if it may help get some info if needed.

@Tim_G oh, yours is 7.2. I never had a problem until recently. maybe it is 7.3 that is the problem.
-
@JaredBusch I'll restore a backup of that VM and turn it on, on my test network... update it and update LIS if needed. I'll let you know if I run in to the same issue as you.

Nope, I just logged onto a machine at another client. They are Hyper-V Server 2012 R2.
This client everything works normally

@JaredBusch Yeah that says v 7.3 too. I'll try that update plan I mentioned and let you know.

So WTF, I have one that works fine using 7.3 native LIS on Hyper-V Server 2012 R2, and one that fails on Hyper-V Server 2016 or Server 2012 R2 DataCenter.

Just looked at another system at another client.
