Black screen after install on xenserver


I installed univention on xenserver using debian template and everything installed fine including dhcp, dns, and other few selected modules.
Now it boots and does show ‘reloading bind9 dns server etc’ but then screen goes black .

Any help?



Just a wild guess: How much RAM does the virtual graphics card have? In the past, increasing this value helped in most cases.

Best regards,

It doesn’t provide option to increase graphics RAM but I can increase main memory.
