While today 2.6.32 is the mainline version of Linux kernel, 2.4 branch is still supported by Linux community developers who fix security bugs there but don’t add any new functionality (unlike 2.6 that grows with new features like a snowball). Sometimes it happens that Linux box runs too much services which cannot be stopped so that admin is not allowed to migrate from 2.4 to 2.6 to keep those services online.
In my example the box runs 2.4.37.7 kernel but Vmware Server 1.0.* fails on it with segmentation fault throwing into the logs the errors below in this post. Does that look familiar to anybody? Is there any solution to run Vmware Server at 2.4.37 kernel? Thank you!

Xen is a free software that runs on a host operating system and allows several guest operating systems to be run on top of the host on the same computer hardware at the same time. The following article tells how to set up Xen cluster based on Debian nodes with cluster virtualization management system Ganeti. Tutorial would be helpful also for Linux newbies as all stages of Xen cluster installation are described in great detail.

It’s proven to be that during software development process, research activities and etc., using of virtulization is invaluable. In my practice I use Vmware Server, so the next article would be useful.
First of all, we need to find where all our virtual machines are in our system. After small search I’ve found vmware files in /var/lib/vmware/Virtual Machines. There are some set of directories each corresponds to some of your already created virtual machines. In my case I was interested in cloning virtual machine with name db1 to new machine db2 and then to db3.

Vmware Server at Ubuntu Feisty 7.04
This step-by-step manual provides instructions on how to install freely available VMWare Server at Ubuntu Feisty Fawn Linux (7.04).
First of all download installation package here and get free serial code. To get VMWare Server working at Ubuntu 7.04 I recommend to download this patch.
To make sure there are all necessary tools installed to get VMWare Server running, execute:
sudo aptitude install linux-headers-`uname -r` build-essentia xinetd
After it’s done unpack installation package and patch:
tar -xvzf VMware-server-1.0.3-44356.tar.gz
tar -xvzf vmware-any-any-update109.tar.gz
Then:
cd vmware-server-distrib
./vmware-install.pl
Choose defaults to questions until installer asks to run vmware-config.pl. Press no and install patch:
cd ../
cd vmware-any-any-update109
sudo ./runme.pl
Now it’s proper time to configure VMWare Server:
sudo vmware-config.pl
Just choose default values (it really worked for me).
When the installation is done, run
vmware
and proceed with using VMWare Server:
