Please see http://ubuntuforums.org/showthread.php?t=2325843&p=13499322#post13499322 for a similar discussion and for a workaround. But please note that to the best I can tell it is still a bug.

I have been using qemu - kvm for several years in different versions of ubuntu (lubuntu). I am trying to migrate from 15.04 to 16.04 and am having a problem. In particular, on my machine (a samsung series 9 with dual core i7 processor and 8gb ram) the following commands worked in 15.04 but do not work in 15.10 and 16.04. FYI, I tested them on a clean machine, where I have created a 60GB image file in its own partition.. In particular, I am using the command to start installing windows 7 and it works in a clean install of 15.04 (yesterday) but not in 15.10 (yesterday) or 16.04 (the day before). I do not get any error messages in my xterminal when running this and do not know how to check for windows error messages. By not working I mean that after loading files it gets to a windows screen and then stays there forever. The command lines used to invoke qemu is: echo "*** Installing windows 7 virtual machine - Step 2" echo "*** Try command for slow mouse" export SDL_VIDEO_X11_DGAMOUSE=0 sudo qemu-system-x86_64 \ -enable-kvm \ -machine pc,accel=kvm \ -cdrom /home/Archives/Software/OperatingSystems.Windows7HP.64/Windows7HP64_Install.iso \ -boot d \ -net nic,macaddr=56:44:45:30:31:34 \ -net user \ -cpu host \ -vga qxl \ -spice port=5900,disable-ticketing \ -uuid 8373c3d6-1e6c-f022-38e2-b94e6e14e170 \ -smp cpus=2,maxcpus=3 \ -m 6144 \ -name DrPhilSS9AWin7VM \ -hda /mnt/Windows7Image/Windows7Guest.img \ -localtime \ -k en-us \ -usb \ -usbdevice tablet& sleep 10 spicy --host 127.0.0.1 --port 5900 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1589153/+subscriptions
