Hi Rusty,

and ended up in the following error.

I've just pushed an update that should disable this test for older versions of glibc. Would appreciate if you let me know whether this fixed your build.

So first thing I would like to know if my XEN installation is compatible with your benchmark suite and if not which are the requirements?

Thank you for your help and support,

    Jan Michael

Hi all,

    I've been working on a set of easy-to-run benchmarks for hypervisor
optimization called virtbench, and the latest commit adds Xen support.


From the README:

    # Build the code
    # Set the guest kernel location and maybe more
    vi ./SETTINGS
    # Run the benchmark (local mode)
    ./virtbench local
    # Run the benchmark (kvm mode)
    sudo ./virtbench kvm
    # Run the benchmark (Xen mode)
    sudo ./virtbench xen
    # Run the benchmark (lguest mode)
    sudo ./virtbench lguest

Feedback welcome!
