    v1 v2  
    743743Imagine you want to build the same RPMs for the just issued Fedora 8, instead of your native distribution. First download the ISO image of your distribution and put it where you have space on your disk. Then call pb to help you create a new virtual machine for that distribution:
    744744{{{
    745 $ pb -p pb -r `pwd` -m fedora_8 -i ~/Download/Fedora-8-i386-DVD.iso newvm
    746 Project: pb
     745$ pb -p netperf -r `pwd` -m fedora_8 -i ~/Download/Fedora-8-i386-DVD.iso newvm
     746Project: nerperf
    747747Action: newvm
    748748Creating the QEMU VM... Formating '/users/qemu/fedora_8.qemu', fmt=qcow2, size=5242880 kB
    … …  
    752752}}}
    753753Then the Virtual Machine is launched booting on your CD, and the rest is just a classical installation of a Linux distribution.
    754 
    755 
     754Once your distribution is installed, stop the VM and relaunch it to finish the setup with:
     755{{{
     756$ pb -p netperf -r `pwd` -m fedora_8 launchvm
     757Project: netperf
     758Action: launchvm
     759Launching the VM /users/qemu/fedora_8.qemu... OK
     760Waiting for VM fedora_8 to come up...           
     761}}}
     762I especially disable firewall and SElinux on the VM. At the end of this initial setup phase log as root on your new VM installation. Check that your update mechanism for yum is correct. Allow your local account (the one running the pb commands) to have access through ssh to the VM, and activate ssh if it's not already done:
     763{{{
     764# mkdir .ssh
     765# scp bruno@victoria2.home.musique-ancienne.org:.ssh/id_dsa.pub .ssh//authorized_keys
     766The authenticity of host 'victoria2.home.musique-ancienne.org (192.168.8.28)' can't be established.
     767RSA key fingerprint is 8c:48:e7:a0:23:fe:81:c6:27:a2:d7:e1:7f:00:02:09.
     768Are you sure you want to continue connecting (yes/no)? yes
     769Warning: Permanently added 'victoria2.home.musique-ancienne.org,192.168.8.28' (RSA) to the list of known hosts.
     770bruno@victoria2.home.musique-ancienne.org's password:

     772# chmod 700 .ssh
     773# chmod 600 .ssh//authorized_keys
     774}}}
     775And check that it's working by connecting to your VM (fr that use the port you  put in your netperf.pb configuration file as vmport):
     776{{{
     777ssh root@localhost -p 2225

     795So now you can finish to set up the VM by installing and configuring all what is necessary for pb to work flawlessly. There is a contributed script in Project-Builder that may help you greatly realizing that (Cf: http://trac.project-builder.org/browser/devel/pb/contrib/pbsetupqemu and its launcher http://trac.project-builder.org/browser/devel/pb/contrib/updateqemu). Try launching:
     796{{{
