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? You can find the domain XML below: <?xml version='1.0' encoding='UTF-8'?> <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>MacOS Monterey</name>
