GTX 1050 on VM

[iomichiamolollo]

Hello, I wanted to know if it's possible to use my 1050 as a GPU on a VM

These are my specs:
CPU Intel Core i7 2600k
Motherboard ASUS P8Z68-V PRO/GEN3
GPU XFX Radeon RX 480 GTR 4GB

and I have the GTX 1050 that I want to use on the VM

No. The vm uses its own emulated video card. All peripherals are emulated. Only the CPU is not.

Enable 3D acceleration in the VM. That way the VM can benefit from the power of accelerated host graphics. But, as Bill mentions you cannot access host hardware directly. It wouldn't be a VM if you could.

Virtualbox and pcie passthrough is still not here. You'd need something like hyper-v or vmware.

Aha, i don't see pci passthrough in Hyper-V or vmware.

Only in ESXi, qemu and xen i see pci passthrough.

Hyper-V on windows server 2016+ can do pci passthrough: just google "deploying-graphics-devices-using-dda"
cant post links...

Aha, i don't see pci passthrough in (...) vmware.

VMware vsphere.

Only in ESXi, qemu and xen i see pci passthrough.

ESXi belongs to the VMWare ecosystem.
QEMU does not allow pci passthrough by itself, it requires kernel access such as KVM. If that was the case then you could just use QEMU on windows for pci passthrough.

Not only "not there", the experimental feature which was there has been deleted. It won't be back, because it was never useful. The only people asking about it were gamers hoping it was possible to share a graphics card with the host (it isn't).

ESX-i is a type 1 hypervisor, so is Hyper-v. Even there they still mediate access to the hardware (like I said, if the guest had direct access it wouldn't be a VM). However the mediation layer is thin. In any case the Type-1 server style VM platform is not the focus of these forums.

Per damineps request for a clear answer to the OP's question:

One has already been given:

No.

you cannot access host hardware directly.

Some versions of Virtualbox up to 6.0.x had PCI passthrough. And you'd need a Linux host, not a Windows host.

Starting in 6.1.x Virtualbox does not have PCI passthrough anymore. PCIe passthrough never existed in any version of Virtualbox, so a GTX 1050, a PCIe card, could never have been inserted into a Virtualbox guest.

So in Virtualbox you cannot insert a PCIe card into a guest.

I do not know what other hypervisors can do PCIe passthrough. That question is good for Google.

I decided to prune this topic of all off-topic discussion, as it did not serve the OP. Hopefully this now gives damineps a clearer idea of the tone of discussion we expect. All further off topic posts will be deleted (at least).

Hello

Reading this topic https://docs.oracle.com/en/virtualizati ... rough.html
show that PCIExpress was supported (the attached card of the example is a PCIExpress card, not an oldstyle PCI card)

But this feature had been removed from Virtualbox 6.1

It would be nice if it will be re add in a future release.

Kind regards

[scottgus1]

Both, regular PCI and some PCI Express cards, are supported.

nbanba's link and the 6.0.0 Virtualbox manual do in fact say that some PCIe was partially supported.

6.0 is still available for download.

If one wants to try to get PCIe passthrough going one can still try it. Keep in mind it's "passthrough" not "sharing", so your host also needs a spare device besides the one it is using now. In other words, you can't share the GTX 1050 video card. You'd need an extra video card. And a Linux host, BTW, this is the wrong forum for the wrong host OS for this feature.

It would be nice if it will be re add in a future release.

You'd have to convince the devs of this on the Bugtracker.
