1. Native virtualization

tbd once we figure out how to use VirtualBox on the mac.

2. Virtualization through libvirt.

This will allow a Mac OS client machine to control machines running on linux with KVM or Xen hypervisor.
Note that it is doubtful that we will ever support such a solution but I provide the steps as a convenience
for users who which to continue using their Macs for development.

2.1 Build it yourself.

2.1.1 Dependencies

*libgpgerror, 1.7: ftp://ftp.gnupg.org/gcrypt/libgpg-error/libgpg-error-1.7.tar.gz
*libgcrypt, 1.4.5: ftp://ftp.gnupg.org/gcrypt/libgcrypt/libgcrypt-1.4.5.tar.gz
*gnutls, 2.8.5: ftp://ftp.gnu.org/pub/gnu/gnutls/gnutls-2.8.5.tar.bz2
*libvirt, 0.7.5: ftp://libvirt.org/libvirt/libvirt-0.7.5.tar.gz

Compile libgpgerror:

tar -xzvf libgpg-error-1.7.tar.gz
cd libgpg-error-1.7
make
sudo make install

Compile libgcrypt:

tar -xzvf libgcrypt-1.4.5.tar.gz
cd libgcrypt-1.4.5
./configure --disable-asm
make
sudo make install

Compile gnutls:

tar -xzvf gnutls-2.8.5.tar.bz2
cd gnutls-2.8.5
./configure
make
sudo make install

2.1.2 Compiling libvirt

Download the sources from http://libvirt.org/sources
I used 0.8.8

configure --prefix=/
make 
sudo make install

2.2 Install it from Homebrew/macports

2.2.1 Homebrew

I have not tried these procedures, if it works, please update wiki.

It is already officially in OSX Homebrew.

http://mxcl.github.com/homebrew/

So, you can install it and "things work" just by doing:

$ brew install

Though, you need Homebrew set up on your system.

2.2.2 MacPorts

Still under review :

https://trac.macports.org/ticket/28161

2.3 Install Mac/fuse

You need to install Mac Fuse to be able to create/mount ext2 disks (which are linux disks).

*Download mac fuse from there
*Download the mac fuse ext2 module from here

2.4 Add your user name to the sudoers.

Change /etc/sudoers and uncomment the tow lines below :

# Uncomment to allow people in group wheel to run all commands
%wheel	ALL=(ALL) ALL

# Same thing without a password
%wheel	ALL=(ALL) NOPASSWD: ALL}}

Add yourself to the wheel group

sudo dscl . -append /Groups/wheel GroupMembership yourusername

Verify, it should not ask for your password.

sudo ls
