qemu convert error..

RobinVossen — Wed, 18 Nov 2009 13:10:20 GMT

Hello I am working on a little CGI App.
And this part converts. Well should convert a Vmware image to a qemu cow hard drive file.

I used the following snipper for example:

Code:

$ for i in `ls *[0-9].vmdk`; do qemu-img convert -f vmdk $i -O qcow ${i/vmdk/qcow} ; done && cat *.qcow >> debian.img

That I stole from kj's blog From Vmware to QEMU

That turned into:

Code:

...

open IMAGE_FILE, "+>IMAGE.qcow" || $sys->p_log("Unable to open als file: $!");

  foreach(@files)

  {

    my $file = $loc ."/". $_;

    $sys->p_log("Processing: $file\n");

    if ($file =~ m/([0-9]*)\.vmdk$/)

    { #

      $sys->p_log("Converting $file..\n");

      my $ret = qx!qemu-img convert -f vmdk $file -O qcow $1!;

      $sys->p_log("Converting Done, returned: $ret\n");

      $sys->p_log("Opening $1 with read-only support.\n");

      sub log_die { $sys->p_log("Unable to open file: $1"); die; } 

      open QCOW, "<$1" || log_die($!);

        $sys->p_log("File Opened: $1\n");

        while (){ print IMAGE_FILE $file; }

        $sys->p_log("Write done, next\n");

      close QCOW;

    }

  }

close IMAGE_FILE;

...

That snipper...
It looks like it works fine... When you look at the logs:

Code:

However it doesnt even write the file that it should create.

Scheduler/VB6 program running in Fedora

pu8y — Mon, 16 Nov 2009 09:43:05 GMT

Hi all,

I have made a vb6 porgram, it is running without any error in windows platform. However, i want it to be run at Fedora too. I run my program with Wine Windows Program Loader in a Linux pc, but the program stuck with an error message:

Run-time error '429':
ActiveX component can't create object

I thought it was the error message because of missing some dll/reference files, so I tried to copy all those related .dll & .ocx file into my wine file. (Just copy and paste into the system32 of wine, no regsvr32 statement to register the .dll as what we always do in Windows.) However, all my efforts are in vain. I not sure what is the cause of this error. Anybody can give me a hint on this issue?

p/s: My purpose to run the vb6 program in linux is because I want to make a scheduler in linux pc so that this program can be run once per day automatically and send email. Any suggestion on how to achieve this also are welcome. I am lost... Many many thanks!

How to kill OfficeCalc?

blnl — Mon, 16 Nov 2009 09:21:59 GMT

OfficeCalc hangs when I try opening some of my .xls documents. When this happens I, no other OpenOffice application can be started. I do not know other solution than to restart my computer.

In System Monitor under the Processes tab, I see soffice.bin (status = uninterruptible). End Process button does not work on this one.

How can I kill OfficeCalc when it hangs like this?

A DivX burning application

stuartguthrie — Mon, 16 Nov 2009 09:03:57 GMT

Hi all,

I was just wondering if anyone knows of an application for Gnome (not KDE) that can burn DivX files to DVD? I cannot seem to find one. Often I get these great documentaries (not copyrighted to my knowledge) that I'd love to have on DVD to show friends.

A HUGE thanks in advance.

[SOLVED] How to update from firefox 3.0 to firefox 3.5 through yum

ehsanulhaq — Mon, 16 Nov 2009 06:37:32 GMT

Hi Everyone:

Recently I have installed Fedora 10. It comes with firefox 3.xx by default. Now I was wondering if there is any way through which i can update it to 3.5 version though yum. I have tried

yum update firefox

but it did not work and returns following messages

Loaded plugins: refresh-packagekit
Setting up Update Process
No Packages marked for Update

I know that one way to update is download the latest Tar package and use it, but I want to totally remove my previous installation and use solely one package i.e. firefox 3.5.

Any suggestions?

Thanks,
Ehsan ul haq

Samba Share Server + XP SP2

yameen101 — Thu, 12 Nov 2009 06:24:31 GMT

We have recently migrated to samba share server from Windows server 2003. We do have a xp with service pack 2 at our clients pc. We have map drives at client pc for share folders. At samba we have created users and assign passwords for users. However we are now facing problem when user try to access share folder through map drive.

The following error is appearing when user double click on map drive.

"An error occured while reconnecting Z: to \\192.168.1.200\share-data

Microsoft Windows Network: Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.

This connection has not been restored"

This problem we do not face, if we allow share folder to all user by checking option "allow to all user" in samba. Whenever we restrict it some user the error become.

We use "net use" command at client system to delete all map drives and then to reconnect it. Then it works ok.

Kindly have your comments.

How to read only files which have end of file using lftp from a folder?

bmklinux — Tue, 10 Nov 2009 16:01:02 GMT

lftp is reading the files which are being created and want to avoid that. Is there is way I can config lftp to read only the files which have reached end of the file in a folder. My ftp source system generates several files and we have a batch shell script which pings the source for every 30 secs and reads the file using the newer than option, lftp reading the larger files which are being created in every 30 seconds even though the file is not fully populated by source.

any help would be appriciated

thx - bmk

Moving Linux configuration on new machine with different hardware

JeromeQc — Sun, 08 Nov 2009 16:54:11 GMT

Hi all,

It took countless hours to configure my Linux (Ubuntu) the way I like it with my specific development environment and I even made a few changes to some application source code.

Now I would like to get a laptop and move the exact same configuration on it, instead of reinstalling everything step by step. I know this would be at least a few days of work to get everything setup the same way because I can't remember all the tweaks I've made.

I know there is an application (APTonCD) that helps to create a Linux distribution but I haven't installed everything from Debian packages. I also know I could use a virtual machine but I would like to avoid this option.

I know some people are using Ghost software to move an image to other computers with different hardware with Windows and based from what I've read, Windows would automatically look for the appropriate drivers to fit with the new hardware.

Does anyone know if I could use a similar tool on Linux? Did anyone had already made this kind of experience?

Thanks

*ml editors

chris81 — Sun, 08 Nov 2009 01:18:24 GMT

Hi

I need your help for finding an *ml/js/java/sql/jsp lightweight editor.

All I want from that editor is to have a simple and easy to use GUI and colored tags. I know about NetBeans (not sure if it's the right name) and Forte4Java, but those 2 are too heavy.

Thanks in advance.

Up to date Repositories?

atrus — Sat, 07 Nov 2009 16:24:17 GMT

One of the main reasons that I stopped using Ubuntu was the lack of upto date repos. Many of the programs that I used on a regular basis were out of date (Eclipse, transmission, pidgin, firefox, etc), Fedora generally had up to date packages, but I wasn't all that much of a fan.

In other words, are their distros that have fairly up to date repos?
