virtual dedicated servers

anyone knows how about i could setup multiple virtual dedicated servers on a single physical server? a lot of people do that, but there seems to be no known software that does it...

any help would be greatly appreciated.

Do you mean Apache VirtualHosts? They can be setup in httpd.conf. If you really need to simulate multiple machines on one, you can use UML.

do you want several IPs on one machine? this is called "IP aliasing" for linux.

do you want partitioning like on the AS400 et al? this is UMLinux for now.

... you need to be a little more specific, if you want to get into hosting business, you should gain some experience first!

hi there
thanks for the replies gentlemen. actually the apache virtual hosting and IP aliasing are something thats used everyday in hosting business, but what realnowhereman mentioned about UML seems similar to what we are looking for.

M. Hirsh, we actually been in hosting business for a while and running quite well too, experiencewise ive been in the networking field for approx 9 years, guess theres no end to gaining experience , fully functional VDS softwares have only come into the scene recently. but thanks for your concern though! i already gave all the details of exactly what i am looking for. a software that runs on a dedicated server which emulates multiple dedicated servers with their own seperate memory and processor space so the end users of the virtual server can have full root access and install any softwares as they please without affecting any of the other virtual servers.

theres also this other one i found called FreeVSD (http://www.freevsd.org/index.phtml). let me know your comments on that too.

as for UML, it seems to only work on slackware and suse... we need to be using RedHat or FreeBSD. so any VDS software that runs on that? anyone?

glad to hear that
i was just afraid of more 14yr old kiddies wanting to be a webmaster and flooding this forum with dumb posts "help - have i been hacked - what to do?", "how do i setup dns?", "how do i setup sendmail?" "ist qmail better than sendmail", "is IIS secure?" and so on...
just read through the old posts with subjects like these. i am sure you´ll understand my concern then...

so you are looking for a real partitioning solution...
this freeVSD looks interesting (from the first glance). if you test it, could you please post your experience?
also, if it works on SuSE, it has to work on Redhat too. freeBSD is another story though, as freeVSD seems to bring its own kernel modules.
i read on a freeBSD mailinglist, that the freeVSD equivalent on BSD is jail(8). can´t tell if this is true though as i am very new to freeBSD...

i´m not hosting myself, but i am working on some hobby-clustering projects. i plaid with the "pvm" software and although it is supposed to do the opposite (run one virtual machine on several physical ones), it should also be able to do it this way with the right configuration (never tried).
i´ll have a look at freeVSD myself too as soon as i´m back from holidays

It works in any distro.

Why?
