David Markey wrote: Why not use paravirtualise? AFAIK paravirtualising Ubuntu is troublesome and requires a little work a the moment (a kernel patch and so on), so we did a quick test para-virtualising the standard "Oracle Enterprise Linux 5 64-bit" provided by Oracle, on top of Oracle-vm and running the same benchmarks. Results were sligthly better but still far from our expectations. Disk writes around 10-15 MB/s. My doubt is: should we expect much better results (and by consequence, there is a big misconfiguration/mistake somewhere in our stack) or these results are typical and unexceptional for this kind of systems? _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
