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

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

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?
