I re-deployed one of my systems to Xenial. For the complexity of going back I took what kernel is currently active which was 4.4.0-224 With that I spun up the Xubuntu 32 bit iso you referred.
For the sake of completeness I also did the same on 4.15.0-20-generic (also with newer qemu of bionic). $ qemu-system-i386 -name xubuntu-18.04-desktop-i386 -m 2047M -cpu host -smp 1 -enable-kvm -machine type=ubuntu,accel=kvm -boot d -cdrom /tmp/xubuntu-18.04-desktop-i386.iso And while the initial loading from the ISO takes quite some time I was easily able to go from the installer into "try Xubuntu" and once the desktop loaded up it was actually quite responsive and just fine. This is true for both kernels/releases that I had tried. Now since we have this yet-unknown relation to the host kernel version, I wanted to ask if you could try the even newer 4.4.0-224 kernel? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1767857 Title: Kernel 4.4.0-122 Breaks qemu-system-x86 Status in linux package in Ubuntu: Confirmed Status in qemu package in Ubuntu: Incomplete Bug description: Fully updated xubuntu 16.04 running kernel 4.4.0-122 breaks qemu- system-x86: black screen displays and qemu-system-x86 runs at 100% cpu indefinitely.
