Next steps in my learning curve

Since a few days I have been screwing around with Openvz and Haproxy (and with that loadbalancing). I'm still waiting for a small KVM box to split into several vps'es to learn new things. But I'm a little bit stuck, what should be the best thing to learn (Might be a big word, but atleast to used it once)? I can think of many things that aren't usefull at all but I'm hoping some of the linux guru's here can give me a few practical tips.

    Make a few VPS, slip the passwords to spammers, play a game of "stop the spammers before you get blacklisted" using only iptables and don't Google it!

    I dont think splitting a KVM is a good idea.
    Get a hetzner or ovh dedi that supports virtualization and install the real deal.
    I suggest you start with proxmox, it has both kvm and ovz.
    After you have an idea how it works (customize it and work with the command line a bit to start/stop, create, modify, change IPs, use venet, veth for ovz) then you can try to install yours from scratch.
    If you are still not confident enough, use ovz-web-panel to help you out.

    That's an useless advice, OpenVZ and Xen PV aren't virtualizations, therefore they don't benefit from a virtualization flag.

    A VPS is easier to diagnose when stuff goes wrong and easier to reinstall.

  • Indeed it is, and i'm on a tight budget.

    Ohh and I want to buy the kvm box from prometeus :P

    I didnt claim they are, just that a real server which supports virtualization offers all the possibilities including KVM/proxmox.
    A KVM is not really much easier to reinstall unless you use templates and I am not happy with those.
    Regarding the diagnostic, that is true, you have a full point there.

  • @Maounique said: A KVM is not really much easier to reinstall unless you use templates and I am not happy with those.

    Maybe the fact you put in an ISO and configure it how you like instead of using templates like OVH or have to wait for a spider KVM to be placed.

    KVM is also a lot cheaper if it's just for learning anyway.

    I was there, I know how it is.
    I was trying to split an Atom for storage plans and tested many versions of everything, from OVZ to Xen-PV. Tried to speed up things working in parallel on the real machine and on a VM and found out the Xen Kernel of Centos5 was failing hard in the VM even tho was full virtualization. And that was not an isolated incident while I had the luxury to change the virtualization software as I pleased.
    It may be a good idea to get a KVM for a limited purpose, but the real server cannot be replaced for more advanced stuff.

    You're way late. Scientists did that back in the 30s.

    Maybe, but didnt do it in their bedrooms or remotely at 1000 Km :)

    Sounds like a start to a porno...

    Today I decided to buy a kvm box at Prometeus. So far I didn't got Proxmox working but I don't think that is ever gonna work on a vps. I will just manually and we will see how it will go :)

    I got Proxmox working on KVM, the kvm part of it doesnt work, but the ovz should.
    I dont remember what were the problems i faced, was some time ago.

  • Oh my, another vm inside a vm ? :p

  • @ErawanArifNugroho said: Oh my, another vm inside a vm ? :p

    I did it before for testing HAproxy.

    I can't get it working, it is unable to find the ip address. Editing the host file doesn't help.

    He should have gone with Inceptionhosting ... :D :D
