DirectAdmin under Xen under CentOS

[nobaloney]

I've decided to build our first VPS server using CentOS 5 and Xen. I can't find any installation instructions for installing Xen on CentOS, and I really thought I knew how to use google .

Can anyone help?

Thanks.

You can try these online tutorials:

http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU
http://www.howtoforge.com/centos_5.0_xen
http://www.cyberciti.biz/tips/rhel-centos-xen-virtualization-installation-howto.html

However, when I installed, I used FluidVM:

http://wiki.fluidvm.com/index.php?title=FluidVM_installation

I didn't need to do much like what is explained in the tutorials above. It was easier and you can get FluidVM for free (for under 5 VMs).

Also, it's important to point out that I also used VMware to test all this.

Thanks. The first link is to install instructions for VPS instances, not for the hypervisor. I'll study the others. The last one looks quite easy; it's a simple RPM; I'll try it first.

I'm presuming I can install FluidVM, do the install, and then delete FluidVM; is that correct?

Also, it's important to point out that I also used VMware to test all this.

Why is it important to me? I'm working on a brand new server in my office, where I can always start over.

So I don't think I need this extra layer. Do I?

Thanks!

Why is it important to me?

Perhaps not - I just like vmware's flexibility with moving vm's between esx servers. That way I can test in a lab environment, build to production and them move to a production esx server.

As far as I know, you can completely disable the FluidVM service and use the server as a standard XEN domu. There's either a wiki article on how to uninstall fluidvm or somewhere in there forums. If you have no joy, I can ask them (as I have an active support account with them).

Now I'm only a bit confused: in Xen terminology (see Wikipedia) domu is not the controlling instance; domu refers to all the vps instances. The controlling instance is referred to as dom0.

There are a few control panels that will do this. I use SolusVM. Others use vePortal. There is the free HyperVM.

One little gotcha is the host node needs to be formatted with LVM if you use SolusVM or HyperVM. I don't know about vePortal. And this may be the standard now. When I first started learning the XEN VM's could run on standard partitions as well. I think the problem with standard partitions is the VM's space could not be resized. I don't remember.

Also with XEN you cannot oversell at all. I do not necessarily like overselling but I do like for the different VM's to be able to share resources to some extent as long as they do not step on each other. That is my personal opinion right now.

The first thing you have to do is to decide if you need a control panel.
If you want my advice is to use Solusvm. Reliable and secure with a good API.

Hi,

why don't install first the xenserver 5.5 after centos and DA?
hxxp://www.howtoforge.com/virtualization-with-xenserver-5.5.0
This is a very usefull solution.

(The other solution the solusvm. One of my server i use solusvm with centos and DA. If you need any help ask Martynas )

Can anyone help?

Thanks.

veportal is good too.

I could never get any further information about solusvm - so I can't comment on it - their website doesn't have a demo, there's not much in the way of screen shots, so if anyone knows where I can look into that one some more, let me know please.

@jlasman
It's worth reading up on Xen, it's terminology isn't that hard to understand. I think one of the most important lessons is to learn how to create Xen Templates. Once you're able to do this, you can store them and let the power of Xen really shine.

You could test it, if you would like to: hxxps://www.soluslabs.com/clients/cart.php?a=confproduct&i=0 (Free 15 day trial)

And here is a video and some screens: hxxp://www.webtuga.pt/produtos/software/solusvm

The thread appears to have gone offtrack a few times, probably because I wasn't specific enough in my first post.

I've closed the thread for now, until I'm ready to move forward (hopefully no more than a few days). I'll re-open it if I need anymore help.

Thanks, all!
