General :: Installation - Create An Image File Of A Running System?
Dec 9, 2010
As I understand it creating an image of a Linux system makes an exact copy of the OS and any user files/configurations/programs etc. What i would love to do is create an image of my work PC and install it at home on my desktop. Can someone briefly explain the process of creating and installing images of Linux systems?
Home OS - windows Want - An image file that can be executed in a virtual machine(VMPlayer or VirtualBox) or booted directly on my home PC.
i have Ubuntu 10.04 installed on a virtual machine. i have made a modification and would like to create a CD of this running system.I guess i need to first make and ISO of the system and the copy to a CD. can anyone give guidance on the process to do this?
All of my PCs are set up to either run Ubuntu directly, or are dual boot Ubuntu and some variant of Windows. One of the things I like about this is that in the rare instances that I get a virus I can simply boot into Ubuntu and run ClamAV to remove the virus from there.
I have a friend who recently picked up a nasty virus and we are having a hard time getting his machine to boot at all without all sort of strange behaviors. Under that scenario I can't trust Wubi to work correctly. Soo....
Is it possible for me to create a bootable CD, DVD or USB drive from my machine? I'd like to use my machine because I can update the virus definitions before I create the image and then use that to clean his machine.
Everything in Linux is a file, right? And everything can be represented by a file? Is there some way I could create a block device file that represents (i.e., provides an interface to) this image file? If so, then I could use fdisk on the device file to split it into partitions, format the partitions, and then mount them as directories. I could create a file system within a file system, which would be fun.
Before installing Centos, I downloaded an image file and burned it to CD using InfraRecorder. It starts to run but does not complete. My machine is a new Intel Q6600 Core 2 Quad CPU with 4G of RAM. It is a 64-bit machine, and I used the 64-bit image. After Centos (which I tried first) failed, I then tried (using the same burning software):
o Slackware o UBuntu o gNewSense o Knoppix o Debian o Fedora o Suse o BSD o Solaris 0 puppy Linux
Most failed similarly to Centos. Knoppix worked fully several times, but I was not enthusiastic about installing it, and eventually (on the 5th iteration), it started to fail in a way similar to Centos, and continues so. Solaris and PuppyLinux worked. Those that failed, failed while attempting to start the 4 CPUs. Solaris and Knoppix (when it worked) succeeded in starting all 4 cpus and I could see the messages.
How to communicate what's happening during a failed boot? Finally, I hit upon the idea of photographing the screen during the failing part of the boot; the file is attached. The photo shows the screen just before it blanks, and the BIOS resets for another try. Please let me know if I can collect any other information. I would like to use Centos as a dual boot on my shiny new machine.
I have a system built and running in exactly the basic configuration I want, with my recompiled kernel, extra packages, special drivers, everything works, life is good. What I want to do is take this exact setup and create an image I can copy onto a bootable USB stick. Is there a way to essentially take the contents of my hard drive and copy that onto a USB stick and then boot directly from that? The use case behind this is that I am building an embedded system of which I may have hundreds of boxes with identical hardware and software configurations. Instead of hard drives, I am going to use USB sticks for cost efficiency and maintenance. My idea is that when it's time to upgrade, I could just image a hundred new sticks and go out and swap them.
My issue is that a standard LiveCD install gets me maybe 25% of the way to a finished system. I need to recompile the kernel for realtime support with my CPU, add some fidgety drivers for some specific hardware, and install a whole bunch of additional packages. I suppose I could create a makefile(s) to replicate all the manual steps of the buildout but that seems like a lot of unnecessary complexity IF I can just image that running system as it is.
I wish to use my laptop to create a system for my Soekris 4801. I don't want to take the server down for the lengthy install ( took 6 hours last time, Fedora 5 ). I want to create the image on a USB drive for the 586 Soekris server on my 686 HP laptop. Then scp the image to the Soekris and reboot and configure the server.
Firstly im a linux newbie so try and bear with me, and make any advice clear anywho Ive been running ubuntu for a while on a single partition. Ive recently been looking into other distros and came across arch linux. As i installed arch it was recommended that you create partitions for various directories, such as boot, tmp etc.
Ive read the advantages of this and would now like to set ubuntu up in a similar fashion, alongside arch. Whats the 'best' way to do this. Can ubuntu use the partitions set up by arch? Will i have to reinstall ubuntu? eh i dont know if my question makes sense since its late here and its a topic i know little about. To put it simply: how do you create a multi-partitioned system running both ubuntu and arch
Well I've decided to move all my data from one VPS to another, and Iwanted to know if there was a way from within Ubuntu to make a full system image backup,ch I can then just transfer to the new Ubuntu VPS, and restore it there ..Unfortunately my VPS control does not have any working backup option right now, so I can only make the backup manually from within Ubuntu, if there is a way to do it
I am unable to create either a file or a directory in a specified path in Linux. I am getting the error "No space left on device". I have checked with df -k and df -i. Free disk space is 28 % and free inodes are 28 %. What else could be the reason?
I need a webserver (LAMP) running inside a virtual machine (#1) running as a service (#2) in headless mode (#3) with part or the whole file system encrypted (#4).The virtual machine will be started with no user intervention and provide access to a web application for users in the host machine. Points #1,#2 and #3 are checked and proved to be working fine with Sun VirtualBox, so my question is for #4:Can I encrypt all of the file system and still access the webserver (using a browser) or will GRUB ask me for a password?If encrypting all of the file system is not an option, can I encrypt only /home and /var/www? Will Apache/PHP be able to use files in /home or /var/www without asking for a password or mounting these partitions manually?
I would like to build a bootable system image on an attached hard disk on a running CentOS machine.The hard disk would be moved to a headless server, where only SSH access would be available. It seems that all the documented install methods assume that the installation runs on the taget machine. In this case, I would like to create a bootable system image of CentOS on a running host system. The new install mage would generally have a newer version of CentOS than the running host system where the image is created. Also, I would prefer to do a text-based install.
The reason for all this is that I have network access to several remote machines. I can ask disks to be moved between machines, but I have no physical access. In order to do software testing, I would like to have several system disks with different installed CentOS versions. It would be easer if I could build the system disks on one single machine. The hardware an all machines is very nearly identical.
I am trying to upload some pics on my Facebook account using Firefox. When I click on Facebook's file upload icon, Firefox bring up a 'File Upload' window. I noticed that smaller image file is previewed on the lower right hand corner, while bigger image file is not. Is there anyway I can change this behavior or maybe change what Firefox is using to browse my files?
I installed ubuntu 10.10 on my laptop and configured a lot(mainly setup git, heroku, rails etc), installed and setup lot of things on it to suit my needs. Now I want to move this setup to another machine and want to avoid all the setup again. Is there a way I can create an installer out of my existing ubuntu installation/partition which I can reuse for other machines?
is it possible to make an image of my current installed os and settings ,and burn it to a dvd so that i can just install it on other machines without installing all my programs again?this can be done with windows xp discs. you can intregate drivers and software onto the installation cd. is it possible with ubuntu? and how do you do it?
I have a CentOS server that has all of the applications and security settings that I want. I would like to create a bootable ISO image of that server that can be installed across a wide variety of hardware platforms. What are the recommended tools for doing this with CentOS?
I have a fedora 11 installation on my machine , with a customized partitioning of the 500GB sata HDD , I wanted to create a exact replica image on a USB stick , for future installations on other 500GB sata HDDs .. while only need to create a copy of the 5 GB (/boot + / ) while the remaining 400 GB + is a Data Logger partition which can be created by a script. I tried doing a rsync .. but have got stuck up with the bootable drive configs et all ..
I just downloaded the FEDORA iso image file. Naturally, the next step is to create a DVD. The problem is I'm using a mininetbook hith no DVD unit and I have not an external one, so I think I can use the USB as an alternative, but I just don't find how to in the documentation, and the applications to burn DVD's dont have the option... how can I do this?
All my torrents go to my home/username/Download/ folder, I could read/write yesterday but now I cant even copy the files to a flash drive.The error i get is "Cannot create regular file '/home/username/Download/file' : Read only file system.
I have a problem with the system backup. I need to create a system image using the command "tar", but my server has physical disks with LVM and I am executing "linux rescue" for recovering the linux image. After restoring the image on the new server reports "kernel panic", this is caused because the new server where I restored the image doesn't have LVM disks.
(I tried to post this earlier and it got lost.) I have a Ubuntu ISO image that I downloaded with Slackware, the only system I have. Ubuntu does not tell how to make a bootstick using anything but Windows,Mac, and Ubuntu. I tried "dd if=...ubuntu... of=/dev/sdb bs=512" and it did not put anything on the stick. Is there a procedure for making such a thing?
