    What kind of errors were you getting? AFAIK, HyperVM don't run on Debian variants.

    I've installed Xen with the guides from:-
    http://www.cyberciti.biz/tips/rhel-c...ion-howto.html

    Then HyperVM with the guides from:-
    http://www.corebsd.com/?p=23

    I can't locate the directory cd /usr/local/lxlabs/hypervm/httpdocs/ on the server. I guess something is very wrong with the installation process.

    Can you list the commands, from history, you used to install HyperVM?

    i.e.
    sh ./hypervm-install-master.sh –virtualization-type=xen

    i.e.
    You have to disable selinux by editing /etc/sysconfig/selinux and changing the line to selinux=disabled and then running
    # $ setenforce 0

    # $ wget http://download.lxlabs.com/download/...tall-master.sh
    # $ sh ./hypervm-install-master.sh --virtualization-type=xen

    After you ran that, did HyperVM install script came back saying everything installed ok?

    If you paste the last few lines after installation, it would help.

    Also, run following commands and paste back output too.

    cat /etc/grub.conf
    df -h
    pvscan
    lvscan
    uname -a

    Umm...the network died after rebooting...If appeared the Xen network adapters are there and conflicting with the physical network interface

    Do I need to install Xen first before HyperVM?

    It doesn't matter. HyperVM would install Xen kernel for you as well. You can try reinstall HyperVM again see if it'll work.

    List ouput of...
    ifconfig -a

    I'm making progress...managed to install Xen but having difficulty installing from .iso file. Any idea how to get around this problem? Google can't provide much info on this problem.

    What is an ideal way to manage Xen? Via CLI, Desktop (VNC) or HyperVM? I'm in the midst of installign HyperVM now.

    And last question on this post, how do I assign a specific CPU/core for the guest to use.

    The ideal way of managing VMs is whatever method you are most comfortable with. For me, is the CLI.

    Since you are new, HyperVM is great. It does have very slight learning curve. But once you are comfortable with it, you should be fine.

    Within HyperVM, you will be able to allot # of cores, priorities. However, I find that "weight" and "cap" sometimes does not work. You have to set up in CLI.

    I am wondering the same. Why are people installing it new?! Surely that has to be the worst idea ever

    Either they cant afford inhouse solutions which can be expected from smaller players and theres nothing thats not completely bug free/out of beta yet.

    Panenthe is due 18th August and looks extremely promising from the public beta and SolusLabs should get back to us.

    VZWave seems to have died and VEPortal is the only current alternative.

    well 'the consortium' said that hypervm is secure, though i doubt it until they release the code as open source and have a look at it my self. till now still no news about the progress and planning of the development

    I managed to installed HyperVM on top of Xen but having difficulty creating Xen VM because HyperVM complaining not enough disk space. Some googling show that I need to tweak something on the LVM but I'm a noob in LVM. Would appreciate some help here.

    Here are the output of df and vgdisplay:-

     df -h
