General :: Ubuntu Server 10.04 - Minimize VirtualBox HDD
Jun 23, 2011
I have Ubuntu Server 10.04 TLS installed on a Virtual Machine in a VirtualBox. The size of the Hard Drive is dynamic growing hard drive and the maximum is 32GB. At the beginning I had 4GB on the Hard Drive and the size of the .vdi was 4GB. Lately the size of data on the disk is 15GB but the size of the .vdi is almost 32GB. Why is that? How can I pack / optimize / defrag the HD so it will be the same size of the data on the disk?

I have Ubuntu server with Apache 2, PHP, and various DBMSs running in VirtualBox on my Mac host for my web development work. To easily create/edit the files I'm working on, I mounted a directory from my Mac host via the VirtualBox shared directory feature to /var/www/. Every file I create on my Mac host has the following permissions on the on the Server: -rw-r--r-- 1 root root 6 2011-07-30 01:27 test.The problem is that most PHPscripts/frameworks/etc.need write access to some files.It is extremely annoying to have to chmod every new file/directory that needs write access.Is there a way to set the correct permissions for the files/directories automatically?

I am trying to start a VirtualBox VM on a separate X screen (in fullscreen) so I can switch between Linux and Windows XP by doing Ctrl + Alt + F<.
I am basically trying to do something like this:
startx "VBoxManage startvm XP" -- :4
startx "VBoxManage startvm "XP"" -- :4 (is this correct for quotes within quotes??)
I get a "bad command line option "VBoxManage" back from the startx script so obviously I am not understanding the rules for how to write "shell magic".
How can I do this correctly, or perhaps there is a better way of achieving a VirtualBox VM on a separate X screen?

I don't know if I saw this minimize effect in ubuntu but definitely have seen it on other nix systems. It's basically a little button in the menu bar that when clicked, "minimizes" the window so that only the menubar shows.how to get it working on ubuntu.

In Ubuntu some applications can be set to minimize instead of exit on close. For example, Empathy minimizes to the system tray (mail icon) when the close button is pressed in the application window. How do I make Evolution do this as well?
Essentially I would like to have Evolution hidden in the system tray instead of having to re-launch it every ten minutes to check for new messages (or leave it open and clutter the taskbar).

Currently the terminal prompt looks like this:[karlis@karlis-desktop current_folder]$How can I minimize the prompt, so that it only shows $ or # without extra info in square brackets?I checked the preferences for the default Gnome-Terminal and Terminator - there are no settings for this. It is pretty hard to use terminal when working in directories with long names.

What are some good Linux commands to make switching between different directories on the command line easier?
I often have to switch between different directories with long names, e.g.
Typically, I use tab completion, so it's something like this:
But it's annoying because all these names are so similar, so tab completion doesn't really save much work.
What tricks do you use to minimize typing in such situations?
I do use pushd and popd sometimes, but here it won't help much because I don't visit the directories in a given order.
For a nice solution, see the accepted answer to my other, related question. Basically, just create an alternative cd command:
function cd2 { select a in $1*; do cd $a; break; done }
It will list all possible completions at once:
And you can pick one by typing its number.

I am building a home server that will host a multitude of files; from mp3s to ebooks to FEA software and files. I don't know if RAID is the right thing for me. This server will have all the files that I have accumulated over the years and if the drive fails than I will be S.O.L. I have seen discussions where someone has RAID 1 setup but they don't have their drives internally (to the case), they bought 2 separate external hard drives with eSata to minimize an electrical failure to the drives. (I guess this is a good idea)I have also read about having one drive then using a second to rsync data every week. I planned on purchasing 2 enterprise hard drives of 500 MB to 1 GB but I don't have any experience with how I should handle my data

I wanted to setup an ssh server on my computer that I, along with some other people I know, could access from outside my home network. I didn't want to give others access to my computer (even if that access was limited), so I wanted to setup the server within a Virtualbox virtual machine.
STEP 1: Create the virtual machine.Create a vm with the distro of your choice. I won't explain how to do that here since there are TONS of guides online about how to do this.
STEP 2: Configure the host to send info to the vm.I found an article that explains why you have to do this and how to do it:URL...I can summarize the article by saying that the vm is hidden from other network computers by the host computer. Therefore, you have to configure the host to send information received on a particular port (any port you choose greater than or equal to 1024 as explained in the above link) to port 22 of the vm (port 22 is the default port for ssh).

I am trying to set up Ubuntu server edition 10.10 in virtualbox (windows host). All is going well, except that I can't figure out how to install the guest additions. I know how to do it in the normal edition of Ubuntu, but when I navigate to media/cdrom, it's empty.

I am running virtualbox on a Mac Mini Server. I would like to install Debian on it and give it an internal static IP address. E.g. 192.168.1.xxx
I am looking at all the downloads. The Mac Mini Server Snow Leopard has no CD/DVD but plenty of disk space.
It will be used as a LAMP webserver, Java, Ghostscript and pdftk but also install ISPConfig on it.
I was looking at this ISO: [URL] Is this ok?
The Mac is a 64 bit Intel based machine. If I wanted 64 bit on the VirtualBox, which 64 bit ISO should I get?

I broke down and spent some $$ on a new server for home use. I mostly do technical research and testing, plus store movies and music. My interests are mainly in the IET iscsitarget performance.
Server system consists of an AMD Phenom II 550, 8GB RAM, 1x 80GB system partition, and a LVM-vg0 software raid5, running Ubuntu 10.04 server x64.
The vg0 consists of 3 x 500GB 7200RPM SATA drives (mdadm) sliced up with 100GB for VBox VMs, one slice is an iscsitarget for a Windows 2k3 server, and another slice iscsitarget for a desktop.
With this setup, the win2k3 server is booted from a .vdi image stored on the ext4 lvm raid5 vg0. Here are the DiskTT stats.
Code:
However, with the Win2k3 server and the MS iscsi initiator I get using DiskTT:
Code:
The speeds are incredibly slow considering a non iscsi connection is screaming fast in comparison. Any ideas?
All nics are 1GB.
Here is my ietd.conf
Code:

I have installed a recent version of CentOS 5 (kernel is 2.6.18-128.el5) as VM in VirtualBox on a Windows 2008 server. When CentOS is totally idle, the CPU on the host (windows) machine is totally pegged from the VirtualBox process. I have read on some other forums that this is a problem with the clock running at 1000Hz and that recompiling the kernel configured with the clock at 100Hz will fix, or at least minimize the problem.
Has anyone else seen this problem? Can someone point me to a good set of instructions on rebuilding the kernel? I followed one set of instructions, but it wasn't for CentOS. After I building everything I was supposed to and copying files over the System.map* and vmlinuz* in the /boot directory (I think I screwed up that one), I went to modify the lilo.conf per the instructions, but I couldn't find it.

I used to be able to access the web server I had running on my guest OS in Virtual Box from my host OS. I also had it set to the network settings of "Host Only Adapter". Then I needed to access the internet directly on the gues OS, so I changed my settings on the guest OS to "NAT" (in virtual box), and in /etc/network/interfaces, I removed the loopback stuff and the static IP I'd put in. Now no matter what I do, I cannot get it back to being accessible from the host os! I even did a completely NEW install of Ubuntu guest OS in Virtual box Guest OS: Ubuntu 10.04 Desktop Host OS: OpenSUSE 11.3 VirtualBox: 3.2.6

Observed on two host systems both with openSUSE 11.3 32 bit using ext4: When a big files, in this case a 1.2 GB and a 1.7 GB is copied from DVD, usb harddrive or shared folder into a Windows 7 32 bit guest system, the copied file is corrupted. The md5sum has changed and until the guest system has been rebooted successive md5sum tests on the same file comes up with various results... After a reboot md5sum tests show consistent results, but a sum different from the original file.

I am having trouble for routing port 80 from a Billion adsl modem to a guest server in VirtualBox. There are quite few different changes from my last setup so I kind of confuse which one is wrong.
I used to use have the setup belowusing modem Linksys WAG354G use static ip 192.168.1.100 for my machine use static ip 192.168.1.102 for my guest VirtualBox server guest OS is serving http listening on port 80 i use bridge from my host OS for VirtualBox set my modem to direct all traffic on port 80 to 192.168.1.102 host OS was Fedora 11
now I useusing modem Billion 7404VNPX use same static address and configuration host OS is Fedora 13
main issue is I cannot reach the guest OS if I navigate to my modem ip address. (e.g. http://192.168.1.1) if I change the modem to direct all traffic to my host OS ip address (192.168.1.100) it works nicely.
I have tried to disable and enable the firewall without any luck.

The only things i need out of it are: mars_nwe (Netware server under Linux) and a reverse telnet server (the dos machine is a bbs) I need the virtual server to support a very old dos machine, and while i COULD use samba for drive mapping, the VNC server I'm useing on the dos machine is a progrm called TINY which pretty much means i'm stuck useing the novell dos network stack.
how best to configure opensuse for this? I'm running the install off of the live-dvd which has quite a bit selected by default. I'm not in need of an x-server or a desktop manager, as this will be a set it up and forget about it once it works VM

I am trying to set up samba in my CentOS virtual machine that is running on a Windows 7 host. I have found a tutorial in the How-Tos on this site but I'm not sure if they are exact and I'm paranoid about messing something up. The link to the tutorial is below. Is there anything that I should do different or anything that I should be aware of? Also, once this is set up, how do I transfer files between the two machines?

This is just re phrasing a question I asked before.I cannot minimize. There's no dash, no little square, no x.There's no "back" arrow..I can go to "quit" which brings me back to the opening screen..."don't ask me what the name of the screen is...as far as I know, there is no name for it.

I am working on the newest version of Ubuntu Linux on VirtualBox under a 64-bit Windows 7 host. When I was working, VirtualBox froze, and I hadn't saved my work in Ubuntu. What should I do?
(This happened after I installed the extension pack for USB 2.0 and I went ahead and tried to access a USB port. I suspect that this led to my current situation.)

I've been looking around for a Linux variant which will install only the software I need rather than everything Ubuntu (for example) puts in by default. This is to create a virtual machine in Virtualbox which has bash, apache, python, perl, SQLite, openssh and a few other programs but nothing else. I'd prefer to go with Ubuntu if possible but another modern distro would do as well (I like using apt-get and yum rather than downloading/compiling etc).
SuseStudio.com, which is probably the best so far.Ubuntu 9.10, by pressing F4 to get the boot options on the install disc, but there is no minimal installation (oops! had the alternate disc instead of the server disc).Arch Linux, slightly confusing install procedure but I might go back and try again.Gentoo, started well but fairly soon the HD on the virtual machine went to 2Gb, even before the installation had started in earnest (I'd partitioned the disks is all).I realise there are various "small" Linuxes around like Puppy, Feather, DSL, etc, but they seem to be aimed at desktop users or as a techie's toolkit, and I want a small-as-possible server distro which can be managed with tools like apt or yum or similar.
