Hi Rusty,

thanks for your work. I tried your benchmark on my XEN installation.

<xm info> release : 2.6.18-1.2835.slc4xen version : #1 SMP Wed Nov 29 21:05:58 CET 2006 machine : i686 nr_cpus : 2 nr_nodes : 1 sockets_per_node : 2 cores_per_socket : 1 threads_per_core : 1 cpu_mhz : 2800 hw_caps : bfebfbff:20000000:00000000:00000180:0000641d total_memory : 2047 free_memory : 1024 xen_major : 3 xen_minor : 0 xen_extra : .3-rc5-1.2835.s xen_caps : xen-3.0-x86_32p xen_pagesize : 4096 platform_params : virt_start=0xf5800000 xen_changeset : unavailable cc_compiler : gcc version 3.4.6 20060404 (Red Hat 3.4.6-3) cc_compile_by : root cc_compile_date : Wed Nov 29 20:56:00 CET 2006 xend_config_format : 2 </xm info>

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.

Regards,

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.

http://ozlabs.org/~rusty/virtbench http://ozlabs.org/~rusty/virtbench/?archive/tip.tar.bz2

From the README:

# Build the code make # 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! Rusty.
