As far I have found there is no such option. -- = 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. However just patching ui/console.c: if (flags & GRAPHIC_FLAGS_DMABUF && !displaychangelistener_has_dmabuf(dcl)) { error_setg(errp, "The console requires display DMABUF support."); return false; } to always return true for dmabuf part works just fine: if (flags & GRAPHIC_FLAGS_DMABUF && !displaychangelistener_has_dmabuf(dcl)) { error_setg(errp, "The console requires display DMABUF support."); return true; } This behavior wasn't in qemu 5.x version.
