Install failure with Centos 5.8 32bit host on Ubuntu 14.04 L

[doc_mike]

I am trying to install a Centos 5.8 32bit guest on Ubuntu 14.04 LTS 64bit host. I want to use an application that requires this particular OS. As near as I can tell from the documentation, this should be possible so the first question is: is it possible?

After the install from the DVD, I ejected the disk and rebooted per the instructions and the during that reboot a message started about a problem with an interrupt, "unknown interrupt or fault at EIP 00000060 c05011ed 000011ec". I'm on a Dell workstation, 16 core CPU E5-2630 v3 @ 2.4 GHz with 32 GB of memory, Gallium 0.4 on NVD9 graphics. The log is attached.

I have no clue where to look. Any suggestions will be appreciated.

Cheers

Mike

Greetings

After some Google searches with the error message I guessed the problem must be related to 32bit vs 64bit memory access via PAE, a term that is new to me. You learn something new everyday. After some related Google searches on how to kill a VM hung in Guru Meditation state, I went into the VirtualBox system system settings and set PAE/NX, being the only control I could find related to PAE. This actually fixed the problem and now the VM boots. I just have to figure out why.

PAE allows a 32bit CPU to address more than 4GBs. Some 32bit OSes may require it to be enabled.

To be a little more specific i686 will require PAE.

I was close.

Yup and now you know more. "Imagine what you will know tomorrow"?

Kudos if you know where that quote came from.

You know I have access to the internet and can do searches and stuff for things like quotes from "Men In Black"? lol

[Perryg]

Well the kudos would have happened if you knew without looking it up.

I'm lucky if I remember what I was told we're having for dinner.

Same problem installing Centos 7 Guest from i386 minimal ISO, on a Windows Server 2012 Virtual Box host. It just hangs.

I enabled PAE/NX, and now it's installing fine.

thank you thank you people,
