Failed to view RedHat 6.4 64bit VM from VNC

Publication Date:  2016-11-28 Views:  287 Downloads:  0
Issue Description

After creating a VM from FusionCompute 5.1 and installing the RHEL 6.4 64bit OS, the user is unable to login to the VM desktop using the built in tightVNC or noVNC options.

Handling Process

this is how the VNC display's the RHEL 6.4 64bit VM:

The solution requires a DHCP server running to provission an automatic IP address on the VM NIC. Restart the VM and make sure that the IP address is set by DHCP and is reachable from the maintenance terminal. Follow the below steps: this part is visible from the VNC, when this window comes press "e"

When this window is displayed, select the option displayed in the window and press "e" again

The next window is like the following one. Over here press "3" and restart the machine

When the machine is restarted, login to the OS using an SSH client like PUTTY, the IP of the machine is provided by the DHCP server mentioned earlier. Use an FTP client like the WinSCP to transfer the attached file to /tmp directory of the OS. The file name is "xorg-x11-drv-cirrus-1.5.2-1.el6_4.x86_64.rpm". The file has been attached with this article as well.

Use the command to install the patch:

rpm -U --nodeps --force xorg-x11-drv-cirrus-1.5.2-2.el6.x86_64.rpm
restart the machine, the Desktop should be viewd normally from the VNC now.

Root Cause

The root cause was identified as a missing display driver from RHEL 6.4 compatible with the FusionSphere VNC


install the display drivers to solve the issue.
