This is just a compat symlink for a very old history.
It should not be used directly anymore, but then also not matter.

I have not seen the same with Ubuntu Desktops, so I wonder what is
different in your setup.

@Sushant - have you tried the same with e.g. libvirt (maybe through 
virt-manager), does it behave the same on that backend?
Furthermore this might be when the UI kicks in, could you set up (on install) 
an ssh client and login to log in when it is black and check what is going on 
at the time?

  I am trying to install xubuntu 18.04 as a qemu guest. The installation
  process goes smoothly and I reboot. After reboot, the boot process
  hangs with black screen and a blinking pointer. I used the following
  steps to install and boot the machine:

  STEP 1:
  sudo qemu-img create /var/lib/libvirt/images/xubuntu18_04.qcow2 30G

  
  STEP 2:
  sudo qemu-system-x86_64-spice -enable-kvm -cpu host -boot d -cdrom 
/home/sushant/Downloads/xubuntu-18.04.2-desktop-amd64.iso 
/var/lib/libvirt/images/xubuntu18_04.qcow2   -m 8G

  
  STEP 3:
  sudo qemu-system-x86_64-spice -enable-kvm -cpu host  
/var/lib/libvirt/images/xubuntu18_04.qcow2   -m 8G

  I tried with ubuntu 18.04(deafult ubuntu) and it also hangs with error
  "removed slice user slice of gdm"

  Also, if I install ubuntu 16.04 as guest, it boots smoothly.

  What should be done?
