same results with catalyst and also kernel 3.14 built with vfio and vfio-vga....
Only one thing to try:
Install windows vm
Disabling(not uninstall) gpu adapter so windows recognize gpu
Install catalyst
Hope this works...
Got these info from archlinux thread...
Nevertheless, today will get my gtx 750 TI Twin Frzr and I'll give it a try despite I'm a loyal AMD guy

Update: as per evilsephiroth's suggestion, the easiest way to achieve all this is to simply change the VM's OS type to 'other'. Thanks evilsephiroth!
I need to run a custom KVM start command to remove the following two options (I believe there is some performance impact to doing so), which broke the later NVIDIA drivers:
hv_spinlocks=0xffff,hv_relaxed
To do this, I ran the VM from the Proxmox web interface, and ran:
ps aux|grep <vmid>
Copy the KVM command and paste it into a shell script, and remove the two options above. chmod +x the script, then run from command line. Mine looks like this:
/usr/bin/kvm -id 175 -chardev socket,id=qmp,path=/var/run/qemu-server/175.qmp,server,nowait -mon chardev=qmp,mode=control -vnc unix:/var/run/qemu-server/175.vnc,x509,password -pidfile /var/run/qemu-server/175.pid -daemonize -smbios type=1,uuid=f1638e3b-a992-4455-9269-d378445383f6 -name gputest -smp sockets=1,cores=4 -nodefaults -boot menu=on -vga none -no-hpet -cpu host,kvm=off,+x2apic -k en-us -m 16384 -readconfig /usr/share/qemu-server/pve-q35.cfg -device usb-tablet,id=tablet,bus=ehci.0,port=1 -device vfio-pci,host=05:00.0,id=hostpci0.0,bus=ich9-pcie-port-1,addr=0x0.0,x-vga=on,multifunction=on -device vfio-pci,host=05:00.1,id=hostpci0.1,bus=ich9-pcie-port-1,addr=0x0.1 -device usb-host,vendorid=0x0624,productid=0x0307 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3 -iscsi initiator-name=iqn.1993-08.org.debian:01:c0f2af6cce1 -drive if=none,id=drive-ide2,media=cdrom,aio=native -device ide-cd,bus=ide.1,unit=0,drive=drive-ide2,id=ide2,bootindex=200 -drive file=/var/lib/vz/images/175/vm-175-disk-1.qcow2,if=none,id=drive-virtio0,format=qcow2,aio=native,cache=none,detect-zeroes=on -device virtio-blk-pci,drive=drive-virtio0,id=virtio0,bus=pci.0,addr=0xa,bootindex=100 -netdev type=tap,id=net0,ifname=tap175i0,script=/var/lib/qemu-server/pve-bridge,downscript=/var/lib/qemu-server/pve-bridgedown,vhost=on -device virtio-net-pci,mac=36:E5:2E:84:34:9D,netdev=net0,bus=pci.0,addr=0x12,id=net0,bootindex=300 -rtc driftfix=slew,base=localtime -machine type=q35 -global kvm-pit.lost_tick_policy=discard
Update: this is no longer needed!
Does anyone know if it's possible to remove those two KVM options through the vmid.conf? It would be more convenient to load the VM through the web interface. Nevertheless, very happy to have this running! I hope this is helpful for others trying to get this working.
I've been able to get this working with an NVIDIA GTX 750 Ti card using the latest 347.52 drivers by using the following setup:
Install pve-kernel-3.10.0-5-pve
Add to /etc/modules:
Add the following options to /etc/default/grub on the GRUB_CMDLINE_LINUX_DEFAULT line:
Run: update-grub
Add the following to /etc/initramfs-tools/modules (find the PCI stub IDs for your card by running lspci -nn | grep NVIDIA):
Run: update-initramfs -u and then reboot into the new kernel.
Boot into the VM using the Proxmox web interface, and install the OS (I had better luck with Windows 8.1 - can't remember specifics though).
Add the following options to /etc/pve/host/qemu-server/vmid.conf (get the PCI address from lspci command, and I added the USB device address for my Avocent KVM DSRIQ USB module, you can do the same for a physical keyboard and mouse):

You can now attach a monitor to the graphics card, boot up the machine, and install the NVIDIA drivers. I also installed VB-Audio Virtual Cable http://vb-audio.pagesperso-orange.fr/Cable/ which provided virtual speakers. I mainly intend to use this machine for Steam in home streaming, so there is only a KVM device attached to the VGA port.

Thanks for the report !
Can I take your infos and put them in the wiki ?
I'll make a patch to remove hyperv enlightments (spinlock,relaxed) with x-vga=on
Absolutely! The patch would be great! Let me know if I can help to test.
Well,I did solve changing os type to other, thus removing hyper-v enlightments...

Wouldn't have even thought of that... worked perfectly! Thanks.
I also wanted to mention I had to revert to 344.75 NVIDIA drivers - newer drivers seem to be inconsistent.
