I am having problem trying to get CentOS 7 Graphical installer to work on XenServer 6.5 (Service pack 1).

I have used CentOS 7 template.

Graphical installer does not work, getting blank screen with cursor only.

I have tried increasing RAM to 2GB and still no luck.

Does anyone know how to fix this issue?

  • As an aside to anyone else searching around: I was using TightVNC on a Windows client (usually plays nice with Xen) and experienced this issue. Using RealVNC worked fine. – s.co.tt Dec 28 '16 at 20:48

You need to start the installer with inst.vnc option. Select option "Install CentOS 7" and then press [tab]. Remove 'quiet' and add 'inst.vnc' to kernel command line. Press [enter].

Selecting VNC installation mode.

After that, wait till the kernel spins up, and you'll end up with the following message:

All you need to do now is use vnc client to connect to IP shown in the message. Port is the standard one, 5901.


When you getting blank screen with blinking cursor, just restart XenCenter and navigate to the tab "Console" of the new VM and you will see correctly presented GUI.
