[SOLVED]Installation unusuable (Xenserver)
« on: November 08, 2011, 10:33:29 am »
I downloaded the Zentyal iso a few weeks back and installed it onto my Xenserver by setting the folder it was in as an ISO repository.

I'm running it with a single core and 2GB of ram allocated, 25GB disk space.

Once it loads the screen alternated between a zentyal desktop screen, and a browser based login screen, but they swap back and forth at high speed and are unusuable.

I did read this forum post: http://forum.zentyal.org/index.php?topic=5248.0
However it doesn't seem to be particularly relevant.

Does anyone have any suggestions? I have some casual experience with Linux, but I'm a long way from being an expert so any ideas gratefully received.

I have a similar problem:
http://www.youtube.com/watch?v=GaMJuB3WqUk

Software runs on virtual machine (XenServer 6.0).
Configuration assigned to virtual machine: 1xprocessor x64 multicore, 2048 MB RAM, 8GB disk space.
Graphic drivers are installed.

Maybe resolution is to low (800x600), how can i change it under console ?

Any other suggestions?

I had the same problem with Xen.  If you must have desktop access,  I suggest installing X2go or similar and remoting into the server.  I found that I didn't need the local desktop but instead use ssh and the web control panel.   BTW the problem disappears if you use some other form of hypervisor (KVM here).

For what it's worth, ESXi 4.1 works perfectly. I haven't tried ESXi5 yet. And as long you only have 1 or 2 hosts, ESXi doesn't need the expensive options. (ok no live migration, but we are still talking small business right?)

Hi, i had the same problem here, but i resolved this by simply installing ubuntu 10.04 with the built in template and then installing zentyal with the instructions from the installation page:

http://trac.zentyal.org/wiki/Documentation/Community/Installation/InstallationGuide?redirectedfrom=Document%2FDocumentation%2FInstallationGuide#Zentyal2.2packages

With this method, you can also install Xenserver tools so you can manage the vm better. When installing with the iso this package can't be installed. This has something to do with virtualization mode.

You don't have a GUI this way, but you configure zentyal with an webinterface anyway.

quick howto:

Create a new vm using the ubuntu 10.04 Lucid Lynx LTS 32 or 64bit template (i have it running with 64bit but 32 bit should work fine too)

Give the machine a proper name

Unfortunatly you can't install ubuntu from an iso in xenserver, so you have to use an installation repository.

The official ubuntu repository i used is: http://archive.ubuntu.net/ubuntu

from here on, you can select the home server, set the ram etc etc.

When you have installed the base installation, you install the xenserver tools by mounting the cdrom:
Code: [Select]
sudo mount /dev/cdrom /media
cd /media/Linux
sudo ./install.sh

Now you have xenserver tools installed, so xenserver can give shutdown and reboot commands and you can view the ram usage.

After this you can add the zentyal repositories:
Code: [Select]
sudo apt-get install -y python-software-properties && sudo add-apt-repository ppa:zentyal/2.2 && sudo apt-get update

If you also want to install zarafa, don't forget to add the deb line in /etc/apt/sources.list!
Code: [Select]
deb http://archive.zentyal.com/zentyal 2.2 extra
Install zentyal with
Code: [Select]
sudo apt-get install zentyal
When done, you can connect to the webinterface like a normal installation where the zentyal installation wizard awaits you!

Ubuntu 10.04 with installed Zentyal manually works fine.
Thanks for your feedback.

The solution is a working one.
Have no 5 systems with Zentyal made exect same way.

You do not need to use pre-build ISO, just use this HOW-TO.

It's normal, that first, I'm trying to install zentyal in this way, in simplest way.

Your post does not give aid.

An update:  I may have found a solution to this problem.  I was converting a VBox image over to KVM when I ran into this flickering screen problem again.  Same sort of setup ie LXDE minimal setup.   Installing the Gnome desktop cures the problem.  No more flickering desktop.
