Thanks for the info. Those xml files will be invaluable. > How to create the logical pool, refer to: > http://libvirt.org/git/?p=libvirt.git;a=tree;f=tests/storagepoolxml2xmlin;h=92d08b31073ade34bc2112694219030130fc5bd1;hb=HEAD Looking at the pool-logical*.xml, pool-logical.xml will not harm an existing data on disk, correct? Whereas pool-logical-create.xml will attempt to create a new VG (and could cause data loss)? > How to create the logical volume with backing store, refer to: > http://libvirt.org/git/?p=libvirt.git;a=tree;f=tests/storagevolxml2xmlin;h=ed26441f354c5183499eae14b56e280fe36c1da6;hb=HEAD Since I already have LVM setup, and an active VG should I just omit the following from my logical vol xml? <source> <device path='/dev/sda2'> <extent start='31440502784' end='33520877568'/> </device> </source> <capacity>2080374784</capacity> <allocation>2080374784</allocation> You can understand I'm somewhat hesitant to do this, as I don't want to destroy or overwrite any existing data. Best, Casey
