So if I do = 1. enable GPU 2. connect the cord 3. enable the host 4. run qemu (I'm not sure, if it's mandatory) 5. disable cord 6. disable GPU 7. enable GPU 8. enable cord 9. run qemu again qemu doesn't crash. but the windows guest doesn't load too - it just hangs with a single core 100% load. Not sure, if it's related, but trying to provide as much info as possible -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1897481 Title: qemu crashes with VGA pass-through, e-GPU, nvidia 1060 Status in QEMU: New Bug description: I try to pass-through nvidia 1060 6gb card, which is connected via ExpressCard (EXP-GDC converter).
