Hi,
I have a headless server (without a window server running) and I’m trying to create a VM
with Intel GVT-g support, where the mediated GPU device is the only graphics device
presented to the guest.
When I try to launch the VM I get the following error:
qemu-system-x86_64: ../src/dispatch_common.c:872: epoxy_get_proc_address: Assertion `0
&& "Couldn't find current GLX or EGL context.\n"' failed.
Do you know why there is no EGL context? Am I missing some necessary parameter?
