I've started looking into KVM to possibly to run alongside or even to end up replacing our current Xen infrastructure. The fact that it's built into the mainstream linux kernel is very appealing.
Are there any Control panels/basic frontends for this at the moment to allow users to Reboot/Reimage their VM's? At the moment its looking as though we would need something inhouse or custom developed
I am currently researching the options open to me for Virtualisation, the two main ones I have seen are Xen or KVM.
I mainly use CentOS (RHEL), but have read that the version of Xen with it is very old, broken and unstable. KVM isn't included in the kernel that ships with CentOS, as it is too old, apparently it was first featured in Kernel v2.6.20. There isn't likely to be an update till RHEL6, which is due for release first quarter of 2010. I can't wait over a year, so need to find another Distro for use as the Host OS/Hypervisor.
I have built a pretty powerful server, it has an Intel Xeon 3230 which has VT - so I might be better off using KVM over Xen. I am going to collocate this server, so realistically I can make this decision only once - as it would be a PITA to re-install a host Linux distro remotely.
I did a search on distrowatch for distros with the latest version of the kernel, and Slackware came up as being just one minor version behind the most current (v2.6.27.7).
Now this distro is very mature, so should be a fairly safe bet, but it is a 32bit version and can't host 64bit VMs. I have 8GB of ram so want to be able to use it all, and offer the choice of 32/64bit VMs. So that's that out of the window.
I have used Arch Linux on and off for a couple of years as a workstation OS, but because it is so bleeding edge, when pacman updates it can break itself. But I suppose if I just use it as the Host OS, and never let it update/reboot, then it won't break. It should be fairly lightweight and stable, as I will be installing the bare minimum packages. I have a management card, so if the server fails to boot, then I can still remote in to fix it.
If I do want to update the kernel, is it possible to update without rebooting? I think it is somehow... unless I can just reboot during an unused time at 3am or something.
As you can tell I am leaning towards KVM on Arch Linux (x86_64). Is this a good plan?
Xen control panel because I just got a server so I can try out using Xen instead of OpenVZ. Most of the control panel's that I've seen only support OpenVZ at this time. Would anyone be able to suggest a good panel that I could try out or look at?
I know HyperVM is one but can it be trusted as of now? I know that they have people working on it and there are no major hacks right now (at least not yet) but would it be suggested to use it?
I am currently using four different web hosts for different projects. All of them offer a web control panel, which is handy. However, I was noticing today that none of them use https to access/use the control panel.

View 10 Replies View RelatedThere's a bit of a project which I am going to be launching hopefully within about a month or so. Its going to be fairly server intensive, and as I don't know what the outcome will be, I wish to host it myself on a few spare machines I have for the time-being.
Now, the issue at this stage is installing all the necessary webserver software and controling it from one page, like a control panel.
I don't mind looking into control panels such as Plesk or any others, but would these automatically install all the software that is needed by the CP - such as Apache, MySQL, PHP, Perl etc?
I'd appreciate if anyone could give me some guidance as far as control panels and web server software is concerned.
i upgraded my UBUNTU to 9.10 in which i cant install the FREE Plesk Version.Damn
So im searching for quality free control panels like plesk.
I found webmin but its only for system not for a website.
does anyone have any suggestions on selecting a control panel? ive seen some products around $300 that appear to be just enough for what i need.
how long is the typical setup time for a control panel?
Windows VPS control panels like HyperVM?
Are there any available?
-Do any control panels work with lighttpd yet?
-What control panel uses the least system resources. I heard Cpanel is a huge hog.
-I also would like to host maybe a gameserver for friends on my dedicated server, what control panel works the nicest with gameservers to not hinder performance on either end?
-I saw a new Control Panel Called Interworx. Anyone heard good or bad about it?
when I was in vps except cpanel and whm I had another control panel for vps , Don't remember what was that I could turn my server off and on for dedicated server except for cpanel and whm what else do I need?
View 11 Replies View RelatedI just want to provide what it takes to change hosting company or moving from one to another.
Here is 10 steps how you can do it.
Please correct me if I forgot something or I am totally wrong (wing-wong)
1.Identify a web hosting company that provides the features and services most suitable for you.
2.Order an appropriate hosting package from the supplier.
3.Use the Control Panel facilities to manage your email boxes and such like.
4.Begin the transfer of your domain or change the domain records and change email settings if required (your new web hosting supplier
should provide guidance and support to make this as simple as possible).
5.Copy all your files from your previous web hosting service.
6.Upload the files to your new hosted web space.
7.Transfer any databases required for your website.
8.Check that all files have been copied and uploaded successfully.
9.Test functionality and content related to any databases.
10.If you have not done so already, cancel your previous hosting service.
By the way I think that the most biggest problem is to know how to get moving from one to another hosting that’s why people always thinks that
they will stick to one hosting company and forget all major problems with that company (downtimes, long servers maintenance and etc.)…
I am trying to analyze cPanel, DirectAdmin and Plesk and will provide all (as much as I can) information regarding how to transfer your website.

I would be glad if you would share some information with me on this forum. Really would be awesome…

It's sort of like Amazon EC2.
I want to set up a virtual machine image once. Then deploy it(it doesn't matter whether it's on the same physical machine or not) to a new machine or overriding existing image on a existing machine. It's fine that the VPS provider charge me a monthly charge for every virtual machine I deploy.
This way, I only need to maintain one master virtual machine.
It'd be even better if I can export a image to my own machine, modify it locally, then upload it for deployment.

I'm aware that millions of websites using shared hosting are configured with name based virtual hosting.
I'm just wondering now how name based vhosts could be a disadvantage for hosting our websites?
Currently we have a static IP address for each website, apache configured with vhosts for each of these IP Addresses.
I was thinking about re-configuring to name based vhosts, use up less IP Addresses and only have one or two for domains to point to per server.
Is there anything I should know about name based vhosts?
Currently I know of the following issues:
- I can't setup SSL (I don't think?) without a unique IP, but this doesn't matter to me.
- Apache may be making DNS lookups?
This post may seem a bit silly overall, I doubt there is anything important to note about name based vhosts, but just wanted to know if anyone knew something I should know.
Our current ip based vhost setup works, but it would be nice to drop usage on all of those IP Addresses and we have no need for IP address access from browsers and whatnot.

I have set up IP-Based Virtual Hosts, as I have been requested to set it up for SSL.
I have successfully set up all redirects and routes using the IFCONFIG and ROUTE.
My query is this, I have noticed that each HTTP request actually has to come in through the Virtual IP address (which is assigned to each site) from outside. Else it just displays the default host. Does this mean I have to have a separate phone line and router for each web-site I wish to host?
I am using Apache on Fedora Core 6.

My server has been kernel panicking on and off irreguarly every 2 days or so since I upgraded to cPanel 11, I'm not entirely sure whether this was the cause however I've isolated the fact it is a kernel issue. I am running CentOS 4.5 and was running Kernel "2.6.9-42.0.8.ELsmp" however switched to the kernel I was running before (2.6.9-42.0.3.ELsmp) and the same issue is still cropping up.
I thought that it may be a memory addressing issue or the like, however from looking up the issue, several C programming forums seem to suggest dodgy applications, the memory usage on the server does always seem fairly low and loads are generally healthy so this would seem to be supported.
The logs before the server kernel panics are as so:
