internal error: process exited while connecting to monitor: egl support is disabled

Sun Nov 11 15:32:41 UTC 2018

Hi Acewind, it depends on the aperture size in your host.

Most of desktop machine cannot modify the aperture size, it with only 256MB aperture size.

The Intel NUC machine can modify the aperture size, you can set 1024MB aperture size with 4 mdev_supported_types all supported. ☺

Thanks
Terrence

The libvirt xml is generated by virt-install command so I didn't notice that. I'll try again tomorrow.
In my host, there's two mdev_supported_types:

  *   i915-GVTg_V5_4
  *   i915-GVTg_V5_8
What does it mean? The physical gpu can only be parted to 4 or 8 vgpus?
Can I part it to only two or even one vgpu?

Hi Acewind,

I am Terrence who just got in touch with you by WeChat, I am glad to see you are using our ISO and found some issues for us, we will make improvements according to all the problems you met. ☺

For this issue, I have double confirmed that the 2.12 qemu in our ISO works well on “dma-buf” feature, the qemu located at “/usr/bin/qemu-system-x86_64”.

I saw you didn’t use our qemu as the emulator but use “kvm-spice”   ```<emulator>/usr/bin/kvm-spice</emulator>```

Can you switch to our qemu and try again?

Thanks
Terrence

I install GVT-g-2018q3.iso on i3-7100U host, with IOMMU enabled.
After apt install virt-manager， I create an win10 instance with vgpu to spice.
Accoring to doc: https://github.com/intel/gvt-linux/wiki/Dma_Buf_User_Guide.
Then it shows an error:

root at home:/home# virsh create win10.xml
error: Failed to create domain from win10.xml
error: internal error: process exited while connecting to monitor: egl support is disabled

The libvirt xml file:
