[ale] Small Clusters for VMs

[Beddingfield, Allen]

Will you have shared storage available (shared LUN or high performance NFS for the virtual hard drives that all hosts can access?)
If so, the easiest free out of the box setup is XenServer or oVirt.  I'm familiar with XenServer, but there are some oVirt fans on here, I know.

    I'm a little behind the times.  Looking to run a small cluster of VM
    hosts, just 2-5 physical nodes.
    
    Reading implies it is pretty easy with 2-5 nodes using a mix of
    sheepdog, corosync and pacemaker running on qemu-kvm VM hosts.
    
    Is that true?  Any advice from people who've done this already?
    
    So, is this where you'd start for small home/biz redundant VM cluster?
    
    I've never done clustering on Linux, just Unix with those expensive
    commercial tools and that was many years ago.
    
    
    In related news - Fry's has a Core i3-6100 CPU for $88 today with their
    emailed codes.  That CPU is almost 2x faster than a first gen Core
    i5-750 desktop CPU. Clustering for data redundancy at home really is
    possible with just 2 desktop systems these days. This can be used with
    or without RAID (any sort).
