Intel GVT-g permissions issue

[elin13]

I'm trying to create a virtual GPU on top of my iGPU in my laptop to passthrough to a VM. I used this guide: 

And when I run 

sudo /bin/sh -c "echo [My-vGPU-UUID] > /sys/devices/pci0000:00/0000:[My-PCI-Device]/mdev_supported_types/[My-i915-GVTg-Type]/create"
(With proper values substituted), It returns: /bin/sh:line 1:/sys/devices/pci0000:00/0000:[My-PCI-Device]/mdev_supported_types/[My-i915-GVTg-Type]/create" permission denied. I already tried running as root. Any suggestions?

[My-i915-GVTg-Type] and [My-vGPU-UUID] aren't intended to be copied and pasted as they are, they're place holders for your specific UUID and GVTg type. How you find those is detailed in the post you linked under the "Setting Up the vGPU" section.

 

Don't just copy and paste cli commands on Linux without understanding what they do, it can be dangerous.

I replaced both of those with the generated uuid and specific version of i915 GVT-g. Otherwise,  the command would have returned with "no such file or directory"

Don't use sudo when running redirects, use "su" in the shell before issuing those commands

Tried that. Still returned with permission denied

Don't use sh is unnecessary, type

 

Just again, use su before

 

echo [My-vGPU-UUID] > /sys/devices/pci0000:00/0000:[My- PCI-Device]/mdev_supported_types/[My-i 915-GVTg-Type]/create

I personally use 

Quote

 

echo [My-vGPU-UUID] | sudo tee /sys/devices/pci0000:00/0000:[My- PCI-Device]/mdev_supported_types/[My-i 915-GVTg-Type]/create

 

Also note that it will respond with Permission Denied if there are no avaliable slots for the device. This can happen if your Desktop Manager takes too much VRAM at startup.
