“In this HowTo I will describe the steps to be taken to prepare a server for OpenVZ virtual machines on Debian 3.1 32Bit Linux. With OpenVZ you can create multiple Virtual Private Servers on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernal patch is licensed under the GPL license, and the user-level tools are under the QPL license.”
Although very interesting i prefer Vmware.
There aren’t many suitable apps like streamtuner and streamripper for windows.I just installed Dapper under Vmware and automatically cp back the mp3’s via winscp3 to the media-player music folder.Works like a charm.

You probably don’t know what OpenVZ is:). Let me explain. It is not VMWare_wanna_be. In fact they are completely different. You could compare VMWare against Xen (but in case of Windows install as VM you need hypervisor support on CPU). So, if you wanna have VM runing OS that supports Xen, you get much, much better performance than VMWare (few times better), if OS doesn’t support Xen and you don’t own CPU with hypervisor,… well… VMWare and QEMU are your friends:)
OpenVZ is something like Solaris Zones, BSD jail… More information here http://openvz.org/
And no, you can’t install windows on it:)
Cool,again something to learn,thanx for the clear comment:)
No prob
But if you need some explanation about it, don’t hesitate to ask. You can always expect answer from me.
But you’re probably better to watch these videos if you’re interested in this topic.
Xen (good explanation what is diff between virtualization[VMWare] and para-virtualization[xen]):
ftp://ftp.belnet.be/mirror/FOSDEM/FOSDEM2006-xen.avi
AppArmour (SELinux like feature [at least it works in the same way], and it provides similiar functionality to OpenVZ, but aproach to the result is completely different, OpenVZ spawns zones like environment trough kernel, while AppArmour and SELinux get their functionality trough LSM [linux security module]): ftp://ftp.belnet.be/mirror/FOSDEM/FOSDEM2006-apparmor.avi
UML (User mode linux) Another OpenVZ like project (works in the same way as OpenVZ): http://user-mode-linux.sourceforge.net/ [no FOSDEM video here:( ]
Linux-VServer [don’t know a lot about this one, or better I haven’t tested it yet, but functionality is OpenVZ-like]
http://linux-vserver.org/
FreeBSD jails:
http://docs.freebsd.org/44doc/papers/jail/jail.html
Solaris zones:

chroot (probably the oldest with the lowest functionality and security and as I was corrected once, it is present on al *X):
http://en.wikipedia.org/wiki/Chroot
OpenVZ and UML are providing that little of functionality which is provided with Solaris zones and FreeBSD jails. Meaning, they can be used in quite a lot of occasions, but solution is not really serious. None of them provides functionality to move service from one server to another with cca. 0s downtime [and this is the only reason why one would make a separate environment for single service [or at least I don’t see the reason for it if migration is not the case], more than adequate security is already provided with either SELinux or AppArmour, speaking linux strictly here. Solaris and FreeBSD have its own tricks in security and they don’t lack in this department either]. This functionality is only provided by VMWare GSX [that is if I remember correctly, I’m not VMWare user. I don’t run a lot of Windows setups and speed downside is one of the main reasons why I don’t use virtualization engines] and Xen [and the fact that only they provide functionality you probably thought OpenVZ provides, but Xen is limited as I already said. Video will explain better].
