I'm not able to reproduce this on a physical host. Works just fine for all the 32-bit kernels that I tested. When you say 'black screen', do you not get anything at all? Not even some BIOS flickering in the beginning?
What do you get when you run the following: $ qemu-system-i386 -cdrom xubuntu-18.04-desktop-i386.iso -enable-kvm -m 2047 $ qemu-system-i386 -enable-kvm -nographic -kernel /boot/vmlinuz-4.4.0-122-generic -append "console=ttyS0 earlyprintk" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767857 Title: Kernel 4.4.0-122 Breaks qemu-system-x86 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1767857/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
