Solution:

During graphical installation of rhel8 beta

Select Minimal Install

But do not select any add on’s on the right side panel.

Now register and attach for receiving updates

subscription-manager register
--username XXXXXX
--password XXXXXX

Registering to: subscription.rhsm.redhat.com:443/subscription
The system has been registered with ID: 77aeb163-a95a-49d0-b52e-cfca1d160474
The registered system name is: rhel8v.example.com

subscription-manager attach –auto

dnf grouplist

Available Environment Groups:
Workstation
Custom Operating System
Server
Installed Environment Groups:
Minimal Install

dnf groupinstall server
dnf grouplist
dnf groupinstall Workstation

Now change the default multi-user.target to graphical.target

[root@rhel8v ~]# systemctl get-default
multi-user.target

[root@rhel8v ~]# systemctl set-default graphical.target

Removed /etc/systemd/system/default.target.

Created symlink /etc/systemd/system/default.target → /usr/lib/systemd/system/graphical.target.

[root@rhel8v ~]# systemctl get-default
graphical.target
[root@rhel8v ~]#

reboot

Good Luck
