I had posted last week about trying to get VNC working. I was never successful nor were multiple admins. But we realized that all the hosts we tried on were VMs. We followed the same procedure ( http://wiki.centos.org/HowTos/VNC-Server) on a machine with physical HW and it worked with no problem. But on the VM I can connect, but I don't get any window displayed. Here is what is in the log:

Anyone have any clues as to what could be wrong and why it works on a physical host and not on a VM?

I believe that I just find the answer for this question. I have been beating up myself for the last few hours and I was getting the same error that you posted.
****************Test Environment************** 2 Laptops 1 of the two laptop has several linux KVMs

The reason why you are not able to connect with the KVM Guest is because by default KVM Guest uses VNC, which will conflict with tiger-vncserver.
What is your current VM environment, to resolved the issue I switch from VNC to spice for the choice of display for the KVM Guest and I was finally able to establish communication with the KVM guest.
Let me know if this works for you.

From the KVM Guest, under "Show Virtual Hardware Detail", I change the type from VNC to Spice from the Display option, which was "Display VNC" prior to the change.
You don't have to make the change if you don't want to as I was able to connect to the KVM Guest after it was started with the following command and the Display was configured for VNC: $ sudo virsh start KVM_Guest
Once there is no sessions for the KVM that you are connecting to, you will be fine.

From the KVM Guest, under "Show Virtual Hardware Detail", I change the

My only access to the host is via ssh so I don't think I can do that.

Once there is no sessions for the KVM that you are connecting to, you will be fine.
I'll try that tomorrow.
Sorry for top posting, this is the only option that the phone allow.
If the host is running a X server you can use -X option with ssh.
$ ssh -X user@host And start virt-manager to manage the VMs. On Oct 20, 2013 11:40 AM, "Larry Martell" larry.martell@gmail.com wrote:

the

My only access to the host is via ssh so I don't think I can do that.
You don't have to make the change if you don't want to as I was able to connect to the KVM Guest after it was started with the following command and the Display was configured for VNC: $ sudo virsh start KVM_Guest
Once there is no sessions for the KVM that you are connecting to, you will be fine.
I'll try that tomorrow. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I am running putty from Windows. I do have X11 forwarding enabled. But I still get 'could not open display' I though perhaps I needed to install Xming, but I don't have admin rights on the Windows box, so I couldn't do that.

yes, you need an X server, like xming, to use X11.
I believe you can run xming without installing it, get the zip version, or the 'portable' version.

I will be able to replicate your environment within a few days are you willing to give it another shot? SilverTip257 had an interesting question with regards to how the network is setup.
I'm assuming that the host has a bridge nic compared to the bridge that is created by libvirtd "virbr0", which has the default network of 192.168.122.0/24.
Can you confirm my assumption and let me know if you are willing to continue to work on a resolution.

I don't know how to answer your question - I am a developer not an admin - but if you give me the commands needed I can execute them. I don't have access to the physical host - it's 2,000 miles away from where I am. I could try and ask an admin there, but they are super busy too and they've moved on to other things (We are really short staffed.)
Thanks!

Good Day Larry,
I finally got the time to build the test environment
KVM Host Network Configuration:
eth4==|
|==bond0==br0
eth5==|
KVM Guest Network Configuration:
Host device bond0 (Bridge 'br0')
I have installed tiger VNC server and made the following changes in /etc/sysconfig/vncserver
VNCSERVERS="2:guest1"
VNCSERVERARGS[2]="-geometry 800x600"
The vncserver was stopped
/etc/init.d/vncserver stop
Configure authentication
vncserver :2 (I was prompt to create and verify the password)
From the remote computer I was able to connect to the CentOS 6.4 KVM Guest using tiger VNC vncviewer.
Vncviewer 192.168.1.31:2
netstat -atulp | grep vnc
tcp 0 0 *:5902 *:* LISTEN 28326/Xvnc
tcp 0 0 *:6002 *:* LISTEN 28326/Xvnc
tcp 0 0 192.168.1.31:5902 192.168.1.157:41034 ESTABLISHED 28326/Xvnc
tcp 0 0 *:6002 *:* LISTEN 28326/Xvnc
Seeing that you are able to connect to the server using SSH, I believe that it's save to assume that the setup is similar to what I created, if you are using a Bridge connection you will not have to close the KVM Guest neither will you have to change the display from VNC to spice.
Let me know if this helps.

I haven't followed this thread that closely, so hopefully, I'm not suggesting something that has already been discarded.
Say the host is called kvmserver and your guest is called kvmguest. While on there, with ssh session
virsh vncdisplay kvmguest
It will tell you if its on display 0, 1, 2, or whatever.
Let's say it's on 0.
On your local machine
ssh -L 5900:localhost:5900 kvmhost
Now, if you do vncviewer localhost, it will open up a console on the remote kvm machine.
If running virsh vncdisplay kvmguest shows 5901 or 5902, then change the 5900 to that number, and change vncviewer localhost to vncviewer localhost:1 localhost:2 or whatever.

Anyone have any clues as to what could be wrong and why it works
on a
physical host and not onI believe that I just find the answer for
this
question. I have been beating up myself for the last few hours and I was getting the same error that you posted.
****************Test Environment************** 2 Laptops 1 of the two laptop has several linux KVMs
The reason why you are not able to connect with the KVM Guest is
because
by default KVM Guest uses VNC, which will conflict with
tiger-vncserver.
What is your current VM environment, to resolved the issue I switch
from
VNC to spice for the choice of display for the KVM Guest and I was finally able to establish communication with the KVM guest.
What exactly did you do to effect this change?
From the KVM Guest, under "Show Virtual Hardware Detail", I change the type from VNC to Spice from the Display option, which was "Display VNC" prior to the change.
You don't have to make the change if you don't want to as I was able to connect to the KVM Guest after it was started with the following command and the Display was configured for VNC: $ sudo virsh start KVM_Guest
That gives me:
error: Failed to reconnect to the hypervisor error: no valid connection error: internal error Unable to locate libvirtd daemon in /usr/sbin (to override, set $LIBVIRTD_PATH to the name of the libvirtd binary)

Anyone have any clues as to what could be wrong and why it works on a
physical host and not on a VM?
I believe that I just find the answer for this question. I have been beating up myself for the last few hours and I was getting the same error that you posted.
****************Test Environment************** 2 Laptops 1 of the two laptop has several linux KVMs
The reason why you are not able to connect with the KVM Guest is because by default KVM Guest uses VNC, which will conflict with tiger-vncserver.
If the VNC consoles are listening on the KVM host's IP address, how could both VNC servers conflict?
I suppose it depends how the VM networking is configured. If your set up is bridged, the VM's VNC server would listen on an IP address different than that of the host.
Just looking for a rational explanation as to why your solution works. Thanks!
What is your current VM environment, to resolved the issue I switch from VNC to spice for the choice of display for the KVM Guest and I was finally able to establish communication with the KVM guest.
Let me know if this works for you.

I had posted last week about trying to get VNC working. I was never successful nor were multiple admins. But we realized that all the hosts we tried on were VMs.

Don't know if this is what you had in mind, but I always set up VNC on my CentOS/OEL VMs running under VMWare as well as under Oracle VM server according to a HowTo I found some time ago on a Citrix blog:

bullets 4) - 12).
In short, this runs VNC as an on-request service via xinetd. Multiple simultanoues connections are possible. Perhaps you might want to give it a try.
