Dec 25, 2010Anyone familiar with QEMU? I'm attempting to load F15 for testing purposes along with REL 6. This is what happens, all goes well until it is actually starts downloading files to the virtual disk which appears to work until it gets to about 1/2 way completed, then it hard crashes(actually shuts the machine down). Also I had to turn of ACPI because when it is enabled it just hangs the VM altogether. I'm wondering if I should also turn off APIC?
Is there some way of loading a VM in verbose mode or debug mode to see what is happening and maybe causing this hard crash. The log files for QEMU shows nothing other then the normal loading of the virtual machine, its given name, source ISO and things of that nature.

General :: Decrease The CPU Usage When Running Virtual Box?
May 28, 2011I am facing an issue with 100% CPU usage under my system when running VirtualBox. Here are some further details:
My System Information:
CPU 1 name: Intel(R) Pentium(R) Dual CPU T2310 @ 1.46GHz
CPU 1 level 1 cache size: 32K Data cache. 32K Instruction cache.
CPU 1 level 2 cache size: 1024K Unified cache.
CPU 1 Mips: 2926.20
[Code].....
Well, each time I run Windows XP from my VirtualBox, I see the CPU usage at almost 100%. I experience a slow system even if no programs were running on my hosted Windows XP version.
I was wondering if there is a way for me to play with the settings so I can slightly enhance the performance. My PC is relatively fast under my Linux operating system. I need to know if there are some tips that I may follow when configuring the settings of my VirtualBox so i can achieve better results.
General :: Find And Decrease File System Space For RAC Servers?
Dec 29, 2010We have recently built some RAC (OS:RHEL55) servers and after the Oracle guys have installed their application, somehow the directory / is using the maximum space. I contacted the Oracle team & they say that their RAC installation doesn't create any files in the / directory. This is the o/p of '/' directory file system:
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/datavg-vol2 498M 382M 62M 88% /
Also, when I checked the file sizes, I found that the following files were taking more space:
/etc/selinux/targeted/modules/active/
-rw------ 1 root root 17M Nov1 base.linked
[code].....
I don't know what these files are doing there, when I did a cat and cheked, I found the files containing this data:
nf_tre--
stem_dbusd_var_run_t...and some stuff like this Unable to decide whether or not to remove these files. Also, is there any way to find out what files are taking more space and whether they can be deleted or not? in order to free up some space in the / direcoty. As there are 10 RACs that we've build, I got to do something to fix this for all of the 10 servers.

Feb 2, 2011today I setup a USB drive to use Qemu to boot Backtrack. It was so easy my grandma could do this! My thanks goes out to anyone who worked on the Qemu project!Now, I am wondering, how hard it is to get a distro to run persistently, using Qemu. I would like to have my .bashrc, apps I install, small scripts I write, etc. saved instead of the default bootup each time.
It doesn't matter which distro it is as long as it is Debian based. I did find this thread which I will try later but it sounds almost like I need to boot from USB first... not quite sure. I was hoping I could get further insight from someone before I waist too much time working toward something that will not happen.

Jun 22, 2010I am trying to write a script to set the SGE job execution order. I named each job with 'job1', 'job2' and 'job3'. I want my script to do: When 'job1' execution is complete, 'job2' is executed; when both 'job1' and 'job2' are complete, 'job3' is executed.
First, I tried this following script and it worked well:

General :: Chroot For Unsecure Programs Execution?
May 13, 2010I have never set-up a chroot-jailed environment before and I am afraid I need some help to do it well.To explain shortly what this is all about: I have a webserver to which users send python scripts to process various files that are stored on the server (the system is for Research purpose).Everyday a cron job starts the execution of the uploaded scripts via a command of this kind: /usr/bin/python script_file.pyAll of this is really insecure and I would like to create a jail in which I would copy the necessary files (uploaded scripts, files to process, python binary and dependencies).
I already looked at various utilities to create jails but none of them seemed up-to-date or were lacking solid documentation (ie. the links proposed in How can I run an untrusted python script)Could anyone guide me to a viable solution to my problem? like a working example of a script that creates a jail, put some files in it and executes a python script?
