Package: qemu-system-x86
Version: 1:9.2.0+ds-5
Severity: normal
I recently upgraded qemu to this version (9.2.0+ds-5) and the console no longer
shows anything. I normally run qemu with libvirt and virt-manager.
To rule out upgraded libvirt, I tried launching qemu with similar options as
libvirt did and -display gtk. I still get the same blackscreen. Appears that
keyboard input works, when pressing enter, the vm starts booting and once the
video driver loads, I'm able to see text and graphics. This works for both
libvirt and standalone.
I tried to change from qxl-vga to VGA and cirrus-vga with the same results.
If I downgrade to 9.0.2+ds-7 it works as expected with both
libvirt/virt-manager and launching qemu directly.
The first version to cause this issue is 9.1.0+ds-2 (I could not find -1)
The system has been fully updated to latest sid as of 20250211 except for a
few python libraries and virt-manager.
This is an example of the command used to launch qemu standalone:
