Stuck at booting 'Ubuntu Minimal 18.04 - KVM' after upgrade os

Hi , I’m using the default image from opennebula market place (Ubuntu Minimal 18.04 - KVM)

the default system and image storage is ceph and the hypervisors is ubuntu 18.04 .

After the upgrade vm ( apt update && apt dist-upgrade -y ) the os was stuck at booting from hard disk.
It’s so amazing that I haven’t any issue with Ubuntu 18.04 image at market place.
I don’t see any error log when the system is booting.

Versions of the related components and OS (frontend, hypervisors, VMs):
I’m using ubuntu18.04 as hypervisors
root@kvm2:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.4 LTS
Release: 18.04
Codename: bionic

opennebula version is : 5.10.4

and I’m using ubuntu 18.04 (kvm ) at market place

Steps to reproduce:

login to vm.
apt update && apt dist-upgrade -y
and then reboot the vm

I’m just getting this result when the os is booting

I realized that the only difference between the two versions (ubuntu 18.04 kvm and ubuntu 18.04 at market place ) are in their kernel.

Does anyone have any advice on which version is best to use in a production environment?
