Do these only remove previous session data so that a new virtual instance cannot see it or does it remove it at the physical level level too so that the data cannot be found anywhere on the physical drive? I know Eucalyptus and KVM use sparse files upon instance creation and the instance thinks the ephemeral space is all zeroes even though it is just sparse. I appreciate any insight in how the two virsh commands work and if they use zeroes, sparse, or some other method.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal>Shawn<o:p></o:p></p></div></body></html>
