Title:
QEMU video freezes with "Guest disabled display" (virtio driver)
Status in QEMU:
New
Bug description:
I am using Arch Linux as my Guest and Host OS, after starting qemu
with the following command:
$ qemu-system-x86_64 -enable-kvm -hda arch-zoom.qcow2 -m 4G -vga
virtio
and waiting for a screen blank, I get this message:
Guest disabled display
And nothing happens after that, I can move the mouse or hit any key,
and the message is still there.
I can still reboot the VM but that's not optimal.
I can reproduce this with the latest QEMU release (5.0.0) or git master,
I also tried this with older releases (4.0.0, 3.0.0) and the issue is still
there.
I can't reproduce this with other video drivers (std, qxl).
With std/qxl the screen will blank a bit and then continue as normal.
