Hi:
If Intel 7th Generation Core will support this feature?

Hello Is is the opergion virtualization issue with special platform. You can use the gvt-staging code for instead now, it is working.

Thanks for your help
now i can create vgpu in my device(i5 7500). kernel is 4.15.0-rc4+.
But I don't found skl_dmc_ver1_27.bin and kbl_dmc_ver1_04.bin on https://01.org/linuxgraphics/downloads/firmware

• sudo dpkg -i linux-image-4.15.0-rc4+_4.15.0-rc4+-7_amd64.deb
  ...
  W: Possible missing firmware /lib/firmware/i915/skl_dmc_ver1_27.bin for module i915
  W: Possible missing firmware /lib/firmware/i915/kbl_dmc_ver1_04.bin for module i915
  I am not sure if this warns influence the final result?

• i had created vgpu and new.img before I used comment line:

  I don't know how to solve this error.

After that
vncviewer :1
I use lspci on guest's terminal, I can see my VGA:
00:02:0 VGA ....
00:04:0 VGA compatible controller: Intel Corporation Device 5912
I changed xrog.conf
cat /etc/X11/xorg.conf

EndSection

Section "Screen"

EndSection
then I reboot ,I can't enter the graphic

Miss the related dmc bin file is make sense, not a problem. Can you add “-vga qxl” into Qemu boot up VM command and try again?

I have added "-vga qxl"
sudo qemu-system-x86_64 -m 2048 -smp 2 -M pc -name gvt-g-guest -hda new.img -bios /usr/bin/bios.bin -enable-kvm -vga qxl -k en-us -serial stdio -vnc :1 -machine kernel_irqchip=on -global PIIX4_PM.disable_s3=1 -global PIIX4_PM.disable_s4=1 -cpu host -usb -usbdevice tablet -device vfio-pci,sysfsdev=/sys/bus/pci/devices/0000:00:02.0/56f07026-e611-11e7-81b4-f36d1cecf706,rombar=0

But I just want to use intel's video card rather than virtual video card to play 3D video game or deep learning. I have to modify /etc/X11/xorg.conf
Section "Device"
Identifier "intel"
Driver "intel"
BusID "PCI:0:4:0" # Sample: "PCI:0:2:0"
EndSection

Section "Screen"
Identifier "intel"
Device "intel"
EndSection

use the same command line
unfortunately, I can't see my Desktop.

Thanks

After you enable the Intel Graphics driver in Linux VM You should connect VM by X11vnc, follow the guide as below: https://github.com/intel/gvt-linux/wiki/GVTg_Setup_Guide#413-linux-remote-protocol-support You must connect vm by vm IP address, it will show the desktop.

when I reboot my host I found I could not find vgpu's uuid in that path(/sys/bus/pci/devices/0000:00:02.0/)
How could I save vgpu device after I create them?

when I create them again I discover an error
echo "4b22bf63-cd51-4b91-9573-b95812783b54" > "/sys/bus/pci/devices/0000:00:02.0/mdev_supported_types/i915-GVTg_V5_4/create"
bash: echo: write error: No space left on device

Thanks
Chuandong

Yes the vgpu uuid path will not be saved after reboot machine. Looks due to your host desktop occupied too much aperture size resource, you can try to restart the lightdm and try to create the vgpu again.

Hello TerrenceXu
Thanks for your help. I think I can connect to guest by vncviewer 192.168.31.5(vm's ip)
I can not use vncviewer :1 to connect the guest. is it true?

But I have two question

1. when i enter the guest I found two VGA card (02.00 and 04.00). can you give me command which one is working in my guest? I just use glxgears to show value.
   

2. In my host. I create two or more vgpu. I want to know if I can set dynamic gpu memory?if ture How to set ?

Thanks
Chuandong
