I was bored, Here is a little example of what VirtualBox can do in Ubuntu Running Windows And Linux Mint Side by side.
I only have a 3.0 ghz with 1 Gig of ram running XP/Mint on Ubuntu Gutsy and I can switch through Os's without any slow down at all, I dont have any reason to run XP or Linux Mint, to me Ubuntu is far better than both.

1-Click Install Innotek VirtualBox:
Add this apt repository to your Software Sources:

deb http://www.virtualbox.org/debian gutsy non-free
The innotek public key for apt-secure can be downloaded here. You can add this key with
apt-key add innotek.asc
Then update repo's:

Click Here to install

Have a CD or DVD lying around that you are sick of putting in the drive every time you need something on the disc?

How about just making an .iso file that you can mount as you need? Or maybe you just want a “master” copy of the media so you can create another copy at a future date.

At any rate it is rather easy to accomplish in Ubuntu:

sudo umount /dev/cdrom
dd if=/dev/cdrom of=file.iso bs=1024

You can also do the same with folders:

mkisofs -r -o file.iso /location_of_folder/

Don’t forget to make a checksum:

md5sum file.iso > file.iso.md5

So you want to create a VMware Server on Ubuntu Gutsy Gibbon 7.10? And you want to run it without the graphical user interface (GUI)?

Well today you are in luck. VMware Server (free), allows you to connect graphically to administer a VMware Server so there is no need to install a GUI on your VMware Server and waste precious RAM.

Let’s get started.

First off, I assume that you already have an install of Gutsy Gibbon server version installed and set to a static IP address. From here on out it is pretty easy.

All we have to do is run the following command to install a few prerequisites before we get started.

First jump to the root account:

sudo su

then:

apt-get install build-essential linux-headers-`uname -r` xinetd xorg-dev

After that is installed we grab the install tar file from VMware.com:

wget http://vmware.com/whatever-the-current-release-url-is

extract the tar:

tar xfz VMware-server-1.*

then move into the newly created directory:

cd vmware-server-distrib

Then run the install script:

./vmware-install.pl

Accept all the default options (unless you have reason not to) and you will return back to the command prompt after installation is complete.

At this point you can connect to the server via the VMware console by entering the IP address of your new VMware Server and the login credentials.

What is Xephyr ?

Xephyr is a X server that runs as a small window within your current X session.

What is it good for ?

There are multiple potential uses for Xephyr:

• Development. You can ssh into a chroot and forward X sessions.
• Forward X over ssh without VNC.

Example: Normally if you ssh -X you can forward x applications. This is not a problem if you are forwarding a single application from a single server. But if you forward multiple applications from multiple servers or a whole desktop, it gets messy (to say the least). You can start a new X session ( Virtual X ), but then you have to Ctl-Al-F7 and Ctrl-Alt-F8 between them.

1. Install Xephyr

Code:

---

sudo apt-get install xserver-xephyr

---

2. Start Xephyr

Code:

---

Xephyr -ac -screen 1280x1024 -br -reset -terminate 2> /dev/null :1 &

---

• The ":1" = your display (displays are numbered starting with 0)
• -ac = disable access control restrictions= allow you to forward X
• -screen 1280x1024 = screen size
• -br = black background
• -reset -terminate= Xephyr should automatically close when the last X client is killed, does not always work.
• 2> /dev/null redirects error messages.

3. Set your display (for X)

Code:

---

DISPLAY=:1.0

---

• Don't forget to set it back after you establish a ssh connection ( DISPLAY=0.0 )

=========================


4. Forward single apps / separate window for each server.

Start Xephyr

Code:

---

Xephyr -ac -screen 1280x1024 -br -reset -terminate 2> /dev/null :1 &

---

Change your $Display

Code:

---

DISPLAY=:1.0

---

Forward a xterm:

Code:

---

ssh -XfC -c blowfish user@server xterm

---

• -X = forward X
• -f = puts your ssh session into the background
• -C = use compression -c blowfish = use blowfish (I am told this is the fastest)

• run "xfwm4" in the terminal for window decorations(substitute your window manager if you are not using xfce).
• xterm config file : http://www.xfce.org/various/Xresources.txt

Any X apps for that server will start in that window.


=========================


5. Desktop:

Start Xephyr

Code:

---

Xephyr -ac -screen 1280x1024 -br -reset -terminate 2> /dev/null :2 &

---

2. ssh into the chroot/server

Code:

---

ssh -XfC -c blowfish user@server xfce4-session

---

• Substitute your window manager for "xfce4-session"

=========================
