kvm viostor driver for iscsi LVM?

[copymaster]

Hi

does it make sense to use viostor drivers for windows kvm machines when the storage is a iscsi LUN (lvm) ?

And can i find out the performance for HDD access? I know several possibilities to do this, but maybe there's a special KVM-solution for this??

yes. and use cache=none.

nothing special, but tools like hdtune helps.
