Comment 2 for bug 1649040

It's the same in 2.8.0 but I will test it again when I get some time for vmware.

I used vmware because it offers better resolution.

After posting this issue I have learned a little about virtio and for a few times I was able to boot it with -vag virtio and this was really nice. I was able to resize and qemu will fill the screen to fit.

But now when I boot with -vga virtio it just sits there and won't start Ubuntu.

These are the options I'm using;

qemu-system-x86_64 -drive if=none,id=drive0,cache=none,aio=threads,format=raw,file=ubuntu.img,index=0 \
-object iothread,id=iothread0 \
-machine type=q35,accel=kvm,kernel_irqchip=on \
-device virtio-blk-pci,drive=drive0,scsi=off,config-wce=off,iothread=iothread0 \
-cpu host \
--enable-kvm \
-smp 2 \
-m 4096 \
-vga virtio \
-soundhw ac97 \
-usbdevice tablet \
-rtc base=localtime

I do not understand how QEMU boots options just fine for a few times, then another time you go back and try and nothing works...
