PVE 4.0 beta - Ubuntu 14.04 container not 64-bit

[mlanner]

Hi,

I've installed PVE 4.0 beta and I ran 'pveam update' to get the latest LXC templates. I then proceeded to download the 'Ubuntu Trusty (standard) template, which downloaded just fine, showing up as 'ubuntu-14.04-standard_14.04-1_amd64.tar.gz'. However, when I launch an image based on this template, if I run 'uname -a' in the container, it shows up as i686, a 32-bit machine.

While I do understand that it is many times desirable to run 32-bit machines in containers, for the application I'm containerizing, it needs a 64-bit OS. Is this simply a mis-labeling of the image or is it pointed to the wrong file? In either case, is there a 64-bit Ubuntu Trusty LXC container in the Proxmox repos that I can download?

Thanks in advance!

Look at this thread from a few days, http://forum.proxmox.com/threads/22757-proxmox-4-0?p=114561#post114561

Your installation is in fact 64bit, but it seems lxc has some small bug so that uname doesn't recognized it correct.

dpkg --print-architecture

Should get you the expected correct result.

Thanks. I'll give that a try.

Well, it was worth a try. Unfortunately using 'setarch x86_64' doesn't work in my case, as the application I'm trying to install is specifically looking at 'uname -a'. I'll keep on digging and will report back here if I find a solution.

Use a bash script to relink uname, as a dirty workaround?

backup your old uname from /bin/uname then save this as the new /bin/uname

#!/bin/bash

setarch x86_64 uname "$@"

should work for your purpose.
