Hi,

Because Debian 6.0 Xen doesn't support tap:aio: and because LVM disks are faster, I wrote modified transfer manager driver for opennebula 3.4.x, that use LVM volumes on local disks in virtualization hosts.

There are 3 kinds:

*) lvm2 - works with shared or not shared filesystem datastore (for system datastore there is parameter in lvm.conf to tell shared or not it is).

*) lvm2ssh - the same, but removed code to detect that datastore is shared.

*) lvm2shared - the same, but with only assumption, than datastore is shared.

URL of all them is at http://mif.vu.lt/~rolnas/one/one34/tm/

Regards, Rolandas Naujikas

P.S. This driver was in almost working condition in opennebula 3.2, but was lost in opennebula 3.4. lvm driver in opennebula 3.4.1 is not for system datastore and is different by design.
