Thanks for responding. The link you have provided is for dell hardware and the
server on which I am facing issue is a Sun Hardware. Will it work on Sun
hardware?

> Hello,
>
> I'm currently testing the KVM part of the new RHEL5.4.
> I'm using IoZone becnhmark to test IO performance.
>
> For my test I have dedicate a LVM partition to the IoZone benchmark :
> iozone -a -U /mnt/bench/ -f /mnt/bench/test-file -R -b <file.xls>
>
> I use the LVM partition in evry test (inside the VM or outside the VM).
>
> Something is strange : IO Disk performance are better in a VM ...
> I have test a KVM VM with the option cache=none for the disk (system and
> bench), but the performance are still better ...

> Well I suppose something (KVM, special optimisation ?) do a cache but I
> didn't
> find anything to control the behaviour ....
