VGA and KVM VPS

[ggsmarket]

Hi eveyone,

I setup my Proxmox with pve-kernel-3.10.0-8 kernel as well.

My system :

E5-1650v3 - 64GB RAM - 240GB SSD - GTX 750

And my first VPS worked with my GPU card as well without error. But when i tried to turn on my 2nd vps (cloned from 1st).
It said :

kvm: -device vfio-pci,host=03:00.0,id=hostpci0.0,bus=ich9-pcie-port-1,addr=0x0.0,multifunction=on: vfio: error opening /dev/vfio/29: Device or resource busy

Is there any solutions to run multiple VPSes with 1 GPU Card?

No. Passing through a device to a VPS is exclusive.

Oh my god! If i work with 1 VPS, why we dont use on direct OS.....
Waste time, resource, and money ,....

Your usecase is not valid for virtualization. Even a fully VDI installation does not provide the features your are expecting.

Thank you for your reply, because i want to use big server to seperate VPSes to run Bluestack with 1 VGA card to save our fee.
I think VMWARE will help me.

I think not *). No virtualizer will at the same time give you full exclusive and shared access to the same hardware.

*) I know this for a fact since at work we run a 25 node VmWare and VmWare VDI setup.

Did you try and get failure ????

No. I do not ever try stop breathing to see if I can survive without because I know that in accordance with the laws of nature this is not possible.
