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...

I've started Ubuntu around 6-8 times, and I have only see the Grub
Boot Splash appear twice, so pretty much without fail it typically
boots past the grub splash and automatically boots...
These are the /etc/default/grub settings; (I only changed these
options GRUB_TIMEOUT=15 and GRUB_GFXMODE=1440x900)
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=15
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
