    KVM Virtualization

    I have been working on a virtualization project at work and so far I have been enjoying kvm. I have two virtual hosts set up with one shared storage server. Eventually we are going to have around six virtual hosts setup and some kind of redundant shared storage. I just wanted to get some opinions on ways to set this up.

    I need to have redundant storage servers for failover. Is there and easy way to do this using the kvm storage pools or will I need to do something different? I would also like to be able to do automatic live migration for loadbalancing and failover. I have done some searching and have not been able to find anything. Does kvm support this? I would also like an easy way to convert a live server to a virtual machine. I am playing around with the vmware converting tool but that keeps failing. I was planning on using that tool then converting the vmware image to a kvm image but have not been succesful yet. Are there any easier or better wasy to do this?

    Thanks

    Why don't you get a storage server on RAID 10 with a few drives and just mount from each VPS the storage that you need?

    I currently have one server in a raid 5 acting as my storage. But if this one server were to go down this would take down all of our vm's. I need to eliminate that single point of failure.

    * ZFS
    * Clouds / GRIDS

    PS: sorry if the answer doesn't come any longer

    Is zfs able to work across multiple servers? I can not rely on any cloud or grid because all of our servers need to be managed in house without a connection to the outside world.

    Please read the ZFS specifications and implementation manuals. Further get familiar with cloud/grid storage/computing as that could be a more flexible alternative depending on future tasks your company wants you to get done. This matter is complicated and I cannot teach you all it takes just in a forum post.

    I believe I have found the best solution for the storage servers. I am going to use this tutorial to set up a high availability nfs server.

    Setting Up A Highly Available NFS Server | HowtoForge - Linux Howtos and Tutorials

    If you know anything about my other questions converning automatic failover with kvm I would appreciate the input.

    Thanks
