I am trying to get VNC working on a Centos 6.4 virtual machine. I followed the directions at http://wiki.centos.org/HowTos/VNC-Server. When I connect from the client, I don't get any errors, but I do not get any window displayed. The log on the server has nothing interesting:

19/10/2013 07:14:27 PM [IPv6] Got connection from client ::ffff:10.250.151.75
19/10/2013 07:14:27 PM   other clients:
19/10/2013 07:14:27 PM Client Protocol Version 3.7
19/10/2013 07:14:27 PM Advertising security type 2
19/10/2013 07:14:28 PM Client returned security type 2

On a physical host (i.e. not a VM) following the instructions from the above site works perfectly. But I've had the same problem on 3 different VMs. My xstartup file is identical on the VM and the physical host.

Is there some trick to getting VNC to work on a VM?

  • The guest OS most likely needs the vncserver attached. What is the output from virsh vncdisplay (guest instance/domain name) – MattSizzle Oct 20 '13 at 02:30

This my step to setup vnc on centOS 6.4:

yum install tigervnc-server
yum groupinstall Desktop

vim /etc/sysconfig/vncservers

Add content:

VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 1024x768"

Set vnc passwor:

vncpasswd

Set boot start:

/sbin/service   vncserver start
/sbin/service   vncserver stop
/sbin/chkconfig vncserver on
/sbin/service   vncserver start
