General :: Cutting Ubuntu To Bone For Virtualbox VM
Mar 31, 2010
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.

I'm developing an embedded Linux (it is almost over now). What I'm struggling with is the system goes unstable by cutting power source frequently and it does not boot anymore. It even does not perform fsck. The system just has a XFCE with a fixed Qt App autoloaded to display some charts. My question is that how commercial embedded Linux distros (like Wifi AP's management Linux, ...) avoid this problem?

I recently moved into a place where I have no control over (or access to) the modem or router, and I've encountered quite an annoying problem. My Internet connection keeps cutting out, not for long periods of time, but just enough time to stop videos from buffering and web pages from loading, and it happens often enough to become a regular thing.
I know there are ways to fix this problem, but unfortunately I'm in a position where I can't. So my question is; are there any external "fixes" I can do to keep the Internet connection alive or to retry connecting every time it fails? Like perhaps a Firefox addon or something I can install?

I'm just looking for a good mpeg cutter for my Ubuntu laptop. I currently use video redo on my Windows PC but that is also my HTPC and is hooked up to the TV. I would prefer not to do it on the TV because of possible burn in issues and would love to be able to take the mpeg files recorded on the HTPC and cut them on the laptop but haven't found a really great application to do that.

Judging by the number of responses (close to zero) to other threads about powertop on this forum, I have little hope in getting any answers. However, I do not know where else could I ask. PowerTop tell me that even after applying almost all the tips and tricks from lesswatts.org, my laptop still consumes over 72 Watts while idling.
Code:
< Detailed C-state information is not P-states (frequencies)
1.60 Ghz 0.0%
800 Mhz 100.0%
Wakeups-from-idle per second : 451.1 interval: 10.0s
Power usage (5 minute ACPI estimate) : 72.5 W (0.3 hours left)
Top causes for wakeups:
[Code]...
Suggestion: Enable USB autosuspend by pressing the U key or adding usbcore.autosuspend=1 to the kernel command line in the grub config This is when I am not touching the laptop. When I am surfing the web or listen to music, it goes up to 2000+ wakeups! How do I cut it further? I am getting like 20-30 minutes max on battery and this is unacceptable cause in Windows I get at least 3 times that.

I've had this problem for a while and wondering if anyone has an idea what is going on.
I'm running 9.10 on a computer at home, and when I VNC into it from my Mac at work.
When I do a right-click copy or ctrl-c, the vnc will crash and won't connect again. I can reach the computer with SSH and reboot, but it's kind of annoying when it does this. Has anyone seen this before and is there a fix?

I'm having video issues with my graphic card while using Ubuntu 10.04 LTS 32 bits. When I'm watching video (Either on ....., or a dvd or whatever) There are horizontal lines cutting the video, like when there's very fast movement it doesn't render the video smoothly and so I get to see like vertical divisions, I don't know how to explain it exactly. I have a driver installed, one that installed automatically when I turned normal effects on, but I don't even know which one it is, I'm very new to this.

I have an html file like this
HTML Code:
Some more HTML code... I would like to cut the above text so i get this: Sometext on multiple lines like this.Sometext on multiple lines like this.Sometext on multiple lines like this. Sometext on multiple lines like this.Sometext on multiple lines like this.
There are other HTML files with similar cuts I need to do, but once I have the method for doing one, I am sure I can do the others.
I think the two logical strings to cut between would be:
I am not sure if these strings are always the start and end of the line respectively, is this makes a lot of difference! Then the HTML tags would need to be stripped to get the text on its own.
I know the commands for removing tags, but searching for a string like class="IOSSectionTitle", and cutting everything before it etc is something I am finding challenging.
Just thought I would add that the HTML does not nec. appear on logical new lines throughout the file and there may be unexpected new lines, but as far as i know the class="IOSSectionTitle" and <img always appears as a string without any new lines between those characters.

Since upgrading to 11.04 I have come across an issue when syncing my music to my Motorola Defy mobile phone. I have a large collection of music, the vast majority of which is ripped from CD and stored in FLAC format. I use Banshee to sync some music onto my phone by dragging and dropping. Banshee converts FLAC on-the-fly to OGG prior to copying the file to my phone.
Since installing Ubuntu 11.04 any songs that i have since synced appear to be cut short. The files seem to be of about the correct size, when the music player starts playing the track it shows the correct total length of the song in the timeline bar but the songs get cut short, usually at 5 seconds into the song but a few seem to last about a minute before skipping to the next.
This morning I tried converting files using Sound Converter and setting the Music folder on my Defy's SD Card as the destination folder. The files all appear to be of the right size, show the correct track length but only play the first 4 or five seconds. I used my other computer, also running Ubuntu 11.04, to transfer a few files and these work just fine.

I have had some issues since installing Fedora 11 on my desktop (well not after I installed it, once I installed the updates). Anyway sound was cutting out, videos were jumping, speeding up with no sound etc online such as ....., when playing local songs and videos etc. Anyway I followed this guide [URL] and that fixed my playing of online videos, music and when I play local music in totem etc. IN fact there is no issues with sound in those.
However; when I try to play a local video in any medial player it jumps sound, crashes, if it starts playing sound it will cut out and if I move the video forward it cuts out and sometimes crashes the video player. Any ideas why that guide fixed all online video and local MP3 but is till messed up playing local videos?

I've been messing around with debian A LOT, getting to know it, seeing what makes it run. I recently screwed up big time and nearly rendered it unusable, but I managed to slowly repair it. However, I was unable to do any kind of auto-DHCP connections. Now when I put eth0 up, the connection will cut out after about 5 seconds, and I can't connect any more until I either restart the networking service or do ifdown then ifup.So can anyone suggest to me any logs I should look for, or any packages I should make absolutelyure I have installed and configured properly? Any config logs that need posting

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 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.)

My question mark key in my keyboard isn't working. ("?"). I've tried to use xev and showkey -k to try to identify at least a keycode and manually use xmodmap to map it. Unfortunately, the keys aren't being detected in neither utilities. I'm using Ubuntu 10.04 in a Virtual Machine (VirtualBox 3.2.4 r62467), and my Kernel is 2.6.32-22-generic. My Host is an Ubuntu 8.04.
When I run xev in my host, I get:
KeyRelease event, serial 30, synthetic
NO, window 0x3600001,
root 0x5d, subw 0x0, time 19346721, (726,722), root:(730,746),
state 0x2010, keycode 211 (keysym 0x2f, slash), same_screen YES,
XKeysymToKeycode returns keycode: 61
XLookupString gives 1 bytes: (2f) "/"
XFilterEvent returns: False
[Code]...
What can this be? It's not a special multimedia key, it's a simple one. I would like to understand what exactly is happening so at least I can try to better debug this issue. If it's detected in my host, why it isn't in my guest?

I have an Ubuntu guest installed on Virtualbox 4.0.4 running on Windows 7 Home Premium. I have two firewall rules for Vbox which allow any, any inbound for both TCP and UDP and those rules have edge traversal enabled. I have host ports 9080 and 9022 forwarded to 80 and 22 on the guest. The Win7 box is on an Ethernet connection
After some testing, I have a netbook with a Wifi connection and Ubuntu netbook remix which cannot make an ssh connection to the Ubuntu guest.
But, the same netbook can telnet to port 9080 on the Win7 machine's address and successfully connect to a web server running on port 80 of the Ubuntu guest.
In order to check this out, I ran initctl stop ssh on the Ubuntu guest, verified thagt port 22 had no listeners, and ran ssh with /usr/sbin/sshd -d -e. This shows various bits of debug info from the console. Then I ran Putty on the win7 machine to connect to port 9022 on it's own IP address (that it got from DHCP) and made a successful connection to the guest Ubuntu.
The variable that I don't know much about is the landlord's cable router setup, but I can't figure out why that would block packets to 9022 but not packets to 9080.

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 am trying to install X on my Arch system, but as you know there is a problem with running X as a guest in Vb.
According to the Wiki, X will work on VB 3.2.9, but every time I try to follow the link the URL is not available. Does anybody know how to get this download?
According to the wiki, 3.2.10 will not work with X, but I am not certain if there is a problem with the version I am currently running (3.2.8).

I'm using VirtualBox 3.1.2 (r56127) on Linux (Ubuntu 9.10 64-bit). I'm trying to use Export Appliance utility to clone my virtual machines over local network using SMB protocol to NAS. I decided to do it because some machines are larger than free space on my local disk drive - lack of space for the clones. Simply, I specify GVFS path in the folder selection dialog box, for example:
/home/mloskot/.gvfs/mloskot on browarekhd/VirtualBox/clones
The process starts but after a minute or so the VirtualBox throws an error. Here is screenshot with the exact error:
Does it mean export over network is not supported? Does it mean there is a bug in VirtualBox? Or, simply I must not have used GVFS path as the one above as it consists of spaces in mloskot on browarekhd ?
UPDATE: Maciek suggested below to copy vmdk file to NAS manually. Generally, it would work, but as I specify in my question, I can't generate vmdk file (by exporting VM locally first) on my box where I keep all my VMs due to lack of disk space.

I am running Fedora on a VirtualBox. Sometimes to allow for performing some real hardware testing, I need to run my development environment on a physical machine. So I need the hard disk of the virtual machine (the .vdi file) to be interchangeably working on both the virtual machine itself and my physical PC by booting a bootable image, mounting the vdi file, and then chrooting to it.
