First

I have been trying to add an instance that can boot from iso the first time to install OS, but I have been having a lots of challenges. I am working with Ubuntu 14.04 LTS

root@host:~# gnt-instance add -t plain -o default+CentOS-6.5 -s 50g -n host.x.x.x  --no-start --no-install -H kvm:boot_order=cdrom,cdrom_image_path=/ios/CentOS-6.5-x86_64-minimal.iso test.x.x.x

Failure: command execution error:

OS Parameters validation failed on node host.x.x.x : Directory for OS default not found in search path

the correct directory is actually stated as indicated above, yet I got the above error which indicates that I have left somethings out.

Output of gnt-os list is below:

root@host:~# gnt-os list

Name

debootstrap+default

 

The output of Tail /var/log/ganeti/commands.log is below:

File "/usr/share/ganeti/2.12/ganeti/cli.py", line 2464, in SubmitOpCode

    reporter=reporter)

  File "/usr/share/ganeti/2.12/ganeti/cli.py", line 2443, in PollJob

    return GenericPollJob(job_id, _LuxiJobPollCb(cl), reporter)

  File "/usr/share/ganeti/2.12/ganeti/cli.py", line 2265, in GenericPollJob

    errors.MaybeRaise(msg)

  File "/usr/share/ganeti/2.12/ganeti/errors.py", line 519, in MaybeRaise

    raise errcls(*args)

OpExecError: OS Parameters validation failed on node host.x.x.x : Directory for OS default not found in search path

 

Really I know something is missing, but I couldn’t fix it. Aside specifying the part to which the iso OS is saved while issuing gnt-instance add command , do I need to do anything or do I need to copy the iso to the debootstrap directory. As it is, the correct part of the directory to the iso is specified, but yet I still get the above error I am a newB, kindly assist.

 

Secondly,

I have already created an instance specifying  debootstrap+default , but  I can’t console into it.

Running gnt-instance console instance.x.x.x just hang, I have been reading up, but I couldn’t solve the problem

Below is the command I used to create the instance, output of gnt-instance info and gnt-instance list

 

gnt-instance add -t plain -o debootstrap+default -s 50g -n host.x.x.x  instance1.x.x.x   

  I started the instance using

gnt-instance start instance1.x.x.x

default+CentOS+6.5 is not in your os list. You should reread the
documentation on the -o parameter here:
http://docs.ganeti.org/ganeti/current/man/gnt-instance.html

you might want to read how to have -o ganeti-os-noop and it explains the
whole process of booting from iso very well:
https://nsrc.org/workshops/2014/btnog/raw-attachment/wiki/Track2Agenda/ex-ganeti-instance-iso.htm

I found the nsrc.org resources all very helpful (troubleshooting serial
console, missing bootloader in wheezy instances, ...)

Benjamin

I have successfully created the instance, but I  still cant connect to the console, I have installed a remote desktop viewer, and a vnc viewer, but yet I still cant connect to the console using either of them. Below is the gnt instance and gnt-cluster verify command output to provide more information.
Your help will really be appreciated.

1. Define "can't connect to the console"? Do you mean you get connection refused, or you get a connection but see a blank screen, or something else?
2. What are the exact commands you used to create and start the instance?
3. Which vnc viewer are you using? I have good experience with TigerVNC Viewer on all platforms.


Note that for windows only the vncviewer[64].exe file is required, you don't need the full TigerVNC installation with the Windows server components.

You definitely want VNC, not RDP (although some viewers will do both - e.g. Remmina for Linux)

4. If you do "ps auxwww | grep kvm", do you see a process for your running instance? Can you show the line here?

Note: your log files show attempts to use "gnt-instance console". That is for the serial console, *not* the VNC console.  But as far as I can see, everything should be set up OK for VNC console (you have vnc_bind_address=0.0.0.0)

Regards,

Brian.

Hello Brian,

Thank you for your assistance.

  

1. Define "can't connect to the console"? Do you mean you get connection refused, or you get a connection but see a blank screen, or something else?

            
          I have downloaded tigervnc as suggested, but I couldn't install it. I had to install xtightvncviewer. below is the error message I got.
              root@host1:~# xtightvncviewer mail.x.x.x :11002
                               Error: Can't open display:

As you explained, using gnt-instance console  mail.x.x.x just hang, as the serial console is not configured.

I tried vncviewer mail.x.x.x :11002 still got the same error.

I have been reading up on this, but I am still not lucky to lay my hands on the appropriate documentation. on how to connect to an instance using a vnc

2. What are the exact commands you used to create and start the instance?

     
      gnt-instance add -n host1.x.x.x:host2.x.x.x  -o noop -t drbd  -s 100G -B minmem=1024m \
               --no-start  --no-name-check --no-ip-check mail.x.x.x
      
     gnt-instance modify --net 0:link=br0,ip=192.168.1.110 mail.x.x.x


      gnt-instance modify --force -B memory=1G  mail.x.x.x
    
     gnt-instance start \
    -H boot_order=cdrom,cdrom_image_path=/home/sysadmin/Desktop/CentOS-6.5-x86_64-minimal.iso \
    mail.x.x.x
 

3. Which vnc viewer are you using? I have good experience with TigerVNC Viewer on all platforms.

Downloads: https://bintray.com/tigervnc/stable/tigervnc/1.6.0

Note that for windows only the vncviewer[64].exe file is required, you don't need the full TigerVNC installation with the Windows server components.

You definitely want VNC, not RDP (although some viewers will do both - e.g. Remmina for Linux)

   I am presently using   xtightvncviewer and unfortunately I could'nt find any guide to install vnc client on ubuntu 14.04 LTS. if you have one, please help
   I am a new to linux, as such I find it difficult to find my way around such challenges.
   Kindly bear with me, I have tried to find a solution to this, this is the 4th day but yet, I couldn't come up with anything.
   I have reinstalled the entire servers, formed a new cluster just to be sure there is no issue with the installation. 

 

 

4. If you do "ps auxwww | grep kvm", do you see a process for your running instance? Can you show the line here?

Note: your log files show attempts to use "gnt-instance console". That is for the serial console, *not* the VNC console.  But as far as I can see, everything should be set up OK for VNC console (you have vnc_bind_address=0.0.0.0)

 

   Your assistance is really appreciated. I feel like I am very close, every other seems ok, but i still feel I am not using the right vnc or command to connect to the instance.

Regards,

You still haven't answered the question about what happened with your original attempt to connect using VNC. Did you get connection refused, or get a connection but see a blank screen, or something else?


 

          I have downloaded tigervnc as suggested, but I couldn't install it. I had to install xtightvncviewer. below is the error message I got.

That is wrong use of X11. You can only run X applications on a 'desktop' version of Linux (with the X environment present). And if you logged into your system as a normal user then changed to root with sudo, it won't work; change back to your normal user.

So, if you want to run VNC under Linux, first get to the point where you understand how to run X applications. See if you can get "xeyes" to work first.

If your normal workstation is Windows or OSX, then I suggest you download and run tigervnc on that. It will be much easier.

Perhaps it's too obvious to mention, but the machine where you run vnc viewer does *not* have to be the ganeti node itself (indeed it normally would *not* be)

I usually get connection timed out. The connection is initiated from Realvnc client  from a Windows 10 system Attached is the screenshot.

I have tried to connect using Realvnc installed on my windows 10, but when I couldn't connect, I decided to connect by installing xtightvncviewer on the master node that is ubuntu 14.04 LTS following a guide online.
apologies please, I am totally new to this, I am just leveraging on the information available to me. Kindly bear with me.

Your assistance and guide is really appreciated.
Thank you.

Hallo Bukar,

I see the Problem for getting refused is, that you want to connect to the wrong Server.
You want to connect to mail.xxx but this server do not have any VNC Server running.
You have to connect to the node-Server this VM is running.

So the right Host would be: host1.x.x.x:11002

Thanks a lot, the error message I get if I try to connect to host1.x.x.x is (getaddrifo: No such host is known. (11001)

I am really in need of help, this is driving me crazy plus hours of studies and no results.

Thank  you, I really appreciate

Typo?
According to your last "gnt-instance info mail.x.x.x"
the port was 11002

its not a typo actually, that is what i get as the error message.
The correct port is specified, but the error message returns port 11001 see the screenshot attached.

I could actually connect as it is, bear with me, the problem was that the widows 10 PC could not resolve the name. on using IP, I could connect.
Although, as soon as it connects it goes off immediately. The screen just flashes. I  will continue troubleshooting.
Thnaks to you all for your contribution I really appreciate.

I have seen compatibility problems with realVNC viewer in the past.

Please download vncviewer64.exe (or vncviewer.exe if you have 32-bit windows) from TigerVNC. There is no installation required - just double-click on it and it starts.

It looks like you are getting very close now. As has already been said, connect to 
<IP address of ganeti node>:<port number of running instance>

By the way, from googling around, I see that 11001 also happens to be the Windows error code for "no such host is known". This is just a confusing coincidence :-)

Sorry I forgot to state that TigerVNC was what I used.
