If not, then it is not a bug, it's a bug fix :) But I might be missing something.. I don't see how this could happen without egl-headless though. -- = Marc-Andr=C3=A9 Lureau -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1926952 Title: SPICE support broken with 6.0 Status in QEMU: New Bug description: Using latest relase 6.0.0 while using Intel GVT-G DMA-BUF and SPICE for usb redirection Qemu won't start: qemu-system-x86_64: The console requires display DMABUF support.
