After migrating physical to virtual, server will not show GUI/XWin

This document (7015637) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise Server 11
VMware vCenter
VMware vCenter Converter

Situation

After SLES physical server was migrated, it would boot fine to runlevel 3 but would not display a gui after running startx or init 5.

Resolution

Install VMware tools (for the given version of vCenter and linux architecture); and restart the guest.

Cause


Additional Information

The driver for the video card on the virtual machine is not included in the kernel.  Installing VMware tools adds the proper driver for video to the machine's config that all works properly afterwards.
