    I provide both OpenVZ and Xen virtual servers.
    I'm wondering for techie people, what you prefer?

    OpenVZ or Xen?

    OpenVZ Pros:
    -Better pricing since provider can oversell.
    -Handles overselling well though
    -Less overhead
    -Easier backup

    OpenVZ Cons:
    -Overselling is easy, but not so detrimental
    -Not complete virtualization; all OS share kernel.

    Xen Pros:
    -Dedicated servers
    -Less likely to be oversold

    Xen Cons:
    -Higher overhead
    -If oversold, you're basically f*cked.
    -Pricing is higher for clients

    How about HyperV or VMware :)

    I wouldn't consider OpenVZ a hypervisor its limited to Linux because its only a container.

    I thought Xen allocated resources to each VM so everyone could have an equal share.

    Cheap OpenVZ VPS can run great one day and then awful the next

    Well,
    I do not like ESXi because it has high overhead.
    Never used their enterprise stuff.

    Have you considered using KVM/QEMU if this is a linux server hosting up the VMs? For any experienced *nix systems admin I would highly recommend KVM. It also won't cost you a dime and gives you full hardware virtualization. I use VMWare on Windows, but I tend to stay away from it on linux.
