Does one has to specify both storage pool and a volume or just the volume is enough (in the VM XML) ? thanks Zvi Dubitzky Email:dubi@xxxxxxxxxx Osier Yang <jyang@xxxxxxxxxx> wrote on 21/03/2011 10:16:50: > From: Osier Yang <jyang@xxxxxxxxxx> > To: Zvi Dubitzky/Haifa/IBM@IBMIL > Cc: libvirt-users@xxxxxxxxxx > Date: 21/03/2011 10:17 > Subject: Re: storage pool vs storage volume > > 于 2011年03月21日 15:07, Zvi Dubitzky 写道: > > Can anybody give a good reference to understand the difference between > > storage pool and storage volume > >> From what I have seem storage volume describes the physical storage media > > and the pool a collection of such > > But from the XML at libvirt I do not exactly understand that . > > > > Take the "directory" pool as example, you can simple imagine > the pool is the directory, and the volume is the files under > that directory. > > Regards > Osier
