Hello,
I tried to install eucalyptus 1.5.1 in ubuntu 10.04. I wanted to install both nc and cc in a single node. When I gave the command 'sudo apt-get install eucalyptus-nc' I get this message 'Virtualization acceleration is not possible'. So I've stopped installation at this step. I was able to install eucalyptus on a single node in centos 5.3 by using 'yum groupinstall Virtualization' command. Is there any equivalent package to be downloaded for ubuntu? Can I install nc in the same node where cc is in ubuntu?
Hello,
eucalyptus 1.5.1 is fairly old: is there any particular reason you want to install such an ancient release?
The message you got, seems to imply that your hardware doesn't support hardware virtualization: if this is the case, KVM (used by default by Ubuntu) will not work. Xen uses paravirtualization by default so it is not affected.

I am using UEC to develop private cloud but at the time of node installation it triggers an error that your system does not support virtualization accelration which in turn would create problem
please suggest do i use xen and if yes how can i use it?
i read some where that for UEC vt-x is highly recommeded
pc cofiguration:
intel core 2 duo
please mail me ur answer if it is possible!
thank you

Hello, the problem in your case is that when you install the node, the hardware of the node does not support virtualization and hence you get the message, hardware virtualization is not supported so the processing of the node will be deaccelerated. This is a limitation of your hardware that it does not support virtualization. The best solution in this case is that if possible switch to a hardware that does support virtualization, otherwise you can use xen which supports para-virtualization. KVM is given as default in ubuntu enterprise cloud.
In order to use xen you can take help from the tutorials that describe how to shift from kvm to xen in uec.
This link may be of some help to you https://help.ubuntu.com/community/Xen
Xen has to be installed on the frontend and change the Hypervisor in /etc/eucalyptus/eucalyptus.conf (The line HYPERVISOR = "kvm" ).
please remember that any changes that are made to /etc/eucalyptus/eucalyptus.conf the eucalyptus must be CLEAN started.
Thank you, Asif
Hello, yes it is possible to use xen in Ubuntu Enterprise Cloud. You need to install xen at the frontend.
then it is important you modify the /etc/eucalyptus/eucalyptus.conf file in the frontend. there you must change the Hypervisor="kvm" to xen.
After that do not forget to CLEAN start eucalyptus.
Thanks, Asif
but when i installed xen on node controller after the installation was finished it crashed the ubuntu server kernel(xen also provide its kernel) so what should i do now should i try it again
i have a doubt whether xen will fulfill my requirment(prevoisly by KVM).
please give me detailed explanation for innstallaton and also configuration if any for xen
thanx

I have clearly stated that xen must be installed on the frontend [i.e, the cloud controller, cluster controller, storage controller and walrus].
Why did you try to install it on the node controller?
The link I provided in my previous message should guide you through the installation process.
But first please specify you cloud topology. Is your clc,cc,sc,walrus and nc on the same physical machine or different. It is
always a good option to install clc, cc, sc and warus on one machine and nc on a separate one. Hope this helps.
Thank you, Asif
You can install xen in the frontend machine. That should work. Its better you download the source code from command line and compile it. Good luck. If you successfully install it, please give us a notification and we can carry out some further research works on using xen and enabling para vitualization to run multiple instances in machines that do not support virtualizations.
Thank you, Asif
