Hi folks,

Does Virtualbox run on Jeos 8.04 Hardy Heron. If YES please advise where can I find documentation for its installation. TIA

Did you try to run the .deb file from the site? If you are missing any dependencies, it's shown in the installer window. Ubuntu JeOS is just like a full Ubuntu, just skimmed down by removing unneeded packages for the OS to run properly.

Yup. I do. You just load the ISO, answer the Qs and stand back. The build takes about 10 mins. You need to apt-get install load linux-headers-$(uname -r) build-essential to build GA, and you can trash them afterwards. and do an apt-get autoremove etc. If you move /var and /home to a second VDI then you can make the first immutable. that way you have almost nothing to backup.

Hi Sasquatch,


Thanks for your advice. I haven't started yet.


I have both Ubuntu 8.04 Server amd 64 installer and Jeos 8.04 Hardy heron installer in hand. I don't know which of them will be more suitable for building VB. I have some documentation in hand on building VB on Ubuntu 8.04 but I can't find doc for Jeos. Besides I expect running 64bit OS on my 64bit AMD PC.

Check with 'uname -r' for what kernel you are using, it will say x86_64 if you run the 64 bit version of the OS. And you should know what you downloaded and installed right? You will get an error about the infrastructure anyway if it's the wrong one .
There is also only two installers for Ubuntu 8.04, the 32 bit version and the 64 bit version. What do you mean with the Server AMD 64 and JeOS Hardy Heron? Do you mean the install ISO files you can install the OS with? Please be a bit more specific in what you have and what you want.

It is a 32bit OS.

Just checked the installer. There is no 64bit version available yet.

Yes, there is another version;

Ubuntu Server Edition JeOS

specific for virtual appliance.

There is little point in having a 64-bit version of JeOS or any VM really at the moment, so even if there was a JeOS 64-bit build, I would still recommend using 32-bit especially for something like JeOS.

The whole raison d'être for JeOS is to act as a base OS for a VM appliance and a VM appliance is design to be a single or integrated application underpinned by the minimal OS needed to support it. The main advantage of a 64-bit architecture arises from the 64-bit data path which can give a 2-4x performance boost for certain types of numeric application, but for general work such as a LAMP application it gives no material benefit. Likewise, 64-bit addressing relaxes the 4Gb application boundary (though the apps that need this like VLDB already tend to be PAE aware). However the main disadvantage in using 64-bit is the code growth and effective halving of the cache size.

Overall, I think that we will gain little from supporting 64-bit VM OSs for the next 2-3 years (eventually Moore's Law will tip the balance and we will get to the point where key apps are only available in 64-bit format).

Noted and thanks

Out of interest I use a dynamic VDI of size 1920Mb as my standard building block for my appliances (see my tutorial All about VDIs for the reasons why). My immutable system VDI actually takes up 684Mb and that is for a full LAMP configuration. The var/home VDI takes up nearly a Gb but that is all nearly all php and database. I have a copy of this forum on one for test purposes.

Keep us posted on how you get on.

PS. I deleted the quote block in yr last post. There's no point in using quote to reply to a full point. Just using postreply makes the thread more readable for others
