Hyper-V - CentOS: Console Keyboard / Video Issues

Hey Experts,

I am seeing an odd issue when accessing a CentOS VM from the console of a Hyper-V host.  If I start the VM then I can connect via the console and everything works fine.  As soon as I take the focus off of the Hyper-V console and do something else and then go back to the console, I can no longer see the keyboard strokes on the instance.  

I am RDP'ing into the host machine.

Others can RDP into the same machine and take over the console and see what I was typing and it works fine for them.

I cannot see what is happening in that console until I restart the machine and stay in the console window.

Any ideas?

Are you able to log on to the CentOS console from within Hyper-V Manager (R.Click VM --> Connect)?

Are the Integration Services up to date in the guest OS?
IT AdminAuthor Commented:
Hey Philip,

Yes I can connect to the console the first time after the server is rebooted.  Once I click the focus to anything else and then go back to the console, I can no longer view what is typed.  The VM still accepts the keyboard input it just doesn't display in the console for me.

I'm running CentOS 6.5 and according to what I have read, Microsoft stopped supporting integration services for CentOS with version 6.3.

Philip ElderTechnical Architect - HA/Compute/StorageCommented:
As I recall anything beyond 6.3 had IS installed within the distro.

Is the Hyper-V host part of a domain? If yes, try RSAT Hyper-V Management on another system with admin access to the host and open a console session there. Does it work?

You are right, Hyper-V integration services are no more available for CentOS distro.

better to use other hypervisor else might have many more other issues like network connectivity issues etc...

Hey Sandy,

Thanks for your comment.  Unfortunately I don't have the option of using another Hypervisor.  We are running Hyper-V in multiple clusters with about 30 VMs so Hyper-V is what we will be using going forward.

Philip ElderTechnical Architect - HA/Compute/StorageCommented:
We have CentOS running on our 2012 R2 Hyper-V clusters without issue. Please refer to the following grid for an explanation of Linux on Hyper-V.

As mentioned, IS is _built-in_ to the distro.

Based on your description
others can RDP in without issue
the problem may be with your client machine versus the remote one.

There are some issues with Win7 and newer RDS clients/protocols. What OS is your client?
IT AdminAuthor Commented:
Hey Philip,

Agreed that it may be my client.  I am running Win 8.1...

Philip ElderTechnical Architect - HA/Compute/StorageCommented:
We have Hyper-V running on pretty much all physical Win8/8.1 systems. I suggest installing Win7Pro in a VM and see if it connects okay.

Make sure your machine is up to date.
IT AdminAuthor Commented:
Sorry I misread your question.  Of our VMs, most are Server 2012R2.  We have about 5 CentOS VMs.  The Windows VMs work fine.  It's only the CentOS VMs that I have any problems with.

Philip ElderTechnical Architect - HA/Compute/StorageCommented:
My interpretation of the line in the quote in my post above was that only your machine/PC has issues connecting to the CentOS VM while others connecting from their machine/PC did not. Is that an incorrect interpretation?
IT AdminAuthor Commented:
Yes Philip, that's a correct interpretation. When I log in as myself on other machines it works fine. However when logging into that system as myself or a different account I experience the issue.

Philip ElderTechnical Architect - HA/Compute/StorageCommented:
Oh, _any_ account on that system has the issue?

Okay, A/V on the system set up differently than the others?
Firewall setup on that system different than the others?
Event Logs on that system give any clues as to what may be going on?
Network Drivers for the NIC out of date?
Network setup for the NIC are mucked up or changed?
IT AdminAuthor Commented:
I've upgraded to Windows 10 an no longer see the issue
