Hyper-V, Citrix 7.5, session lock-ups, video card

I have a hyper-v host, the hyper-v host is running a server 2012 R2 server, RDS remote app and citric 7.5 XenApp.  The users are having their sessions lock up and the only fix is to reboot the server.  Of course, we have worked this to death.  The Hyper-V host has massive resources.  The VM has more than ample resources and the resource monitor is showing that the VM has plenty of resources.  

What I am wondering is if the graphics card on the host could be an issue?

The host only has a 256 meg video card and we are supporting 25 users on the terminal server.  I'm thinking the video card is not enough and we need to install a better video card.

I was just looking mostly for some feedback on how important the video card of the host is in this environment.

any thoughts on the possibility of the host video card locking up the Citrix sessions would be appreciated.

Thanks

Cliff

Normally in a basic setup of a VDI/Xenapp environment there is no need for a VGA card. The only reason you would like to use this is when you like to transform the card onto a virtual machine.
VGA memory is also taken from the normal memory and even video rendering is done by the CPU.

The only way you would be able to use the VGA card is if you actually redirect the VGA card to a virtual machine and not use the "default" video card for a virtual machine. When using VMWare e.g. you could use vSGA (Virtual Shared Graphics Acceleration), this functionality shares the GPU memory between different machines or Virtual Direct Graphics Acceleration (vDGA), this attaches a fysical card directly to the virtual machine (passthrough).

So no, i don;t see why your VGA card would have anything to do with this issue as it is not being used at all in "normal" circumstances..

How many guests on your host?  I've seen Virtual environments before where the numbers for utilization look great from the host, the Guest and the SAN and the only thing done was to reduce the number of guests on the host and suddenly performance picked up.

Why I have seen this happening is the simple fact that most SAN's can't cope with the tremendous amount of IOPS. Starting up a Windows 7 machine alone takes up to 2000 IOPS. So boot storms could cause heavy IO and that would cause the server to not be able to accept incoming IO request.

Have you checked the IO or disk queue length on the Hyuper-v host itself? (not the VM's).

It was the video card.  We disabled the onboard, added an nVidia that was RDS approved and the problem went away.
