<p>Got a little issue when compiling Windows QT using Gitian. BTW Im using a Ubuntu 12.04 64bit VPS. </p>

<p>So I am using the instructions here : <a href="https://cryptocointalk.com/topic/2966-bitcoin-scrypt-v120-source-code-and-compile-instructions-for-linux-windows-and-mac/?p=25594" rel="nofollow">https://cryptocointalk.com/topic/2966-bitcoin-scrypt-v120-source-code-and-compile-instructions-for-linux-windows-and-mac/?p=25594</a></p>

<p>Everything works pretty much fine until step 20 (sudo bin/gbuild ../bitcoin/contrib/gitian-descriptors/qt-win32.yml)</p>

<p>When I get this error : </p>

<p>What am I doing wrong ? </p>

<p>BTW step two did not go so well either : ls -l /dev/kvm did not return anything but I suspect it wasn't anything too important and other steps worked fine until this. </p>

The first line of your error states that kvm is not loaded. The command `ls -l /dev/kvm` checks the dev/kvm device and shows nothing. There is your problem. Do you meet the requirements?

# Gitian Build Issue - Windows

(Asked by: username_0 on 2014-07-24)

Got a little issue when compiling Windows QT using Gitian. BTW Im using a Ubuntu 12.04 64bit VPS.

So I am using the instructions here : <https://cryptocointalk.com/topic/2966-bitcoin-scrypt-v120-source-code-and-compile-instructions-for-linux-windows-and-mac/?p=25594>

Everything works pretty much fine until step 20 (sudo bin/gbuild ../bitcoin/contrib/gitian-descriptors/qt-win32.yml)

When I get this error :

**\*\*\*\*\*\*\*\*\*** WARNING: kvm not loaded, this will probably not work out

--- Building for lucid i386 ---
Stopping target if it is up
Making a new image copy
qemu-img: Could not open 'base-lucid-i386.qcow2'

from bin/gbuild:230:in `each'
from bin/gbuild:230

from bin/gbuild:228

What am I doing wrong ?

BTW step two did not go so well either : ls -l /dev/kvm did not return anything but I suspect it wasn't anything too important and other steps worked fine until this.
