I don't see any similar issues running a stock 6.14.4 kernel, qemu 9.2, Lin= ux guest (6.14.3) running nvidia 570.144, youtube playback in chromium. Please provide full VM XML or libvirt log, host 'sudo dmesg', host 'sudo ls= pci -vvv', guest nvidia driver version. --=20 You may reply to this email to add a comment.
