They has been designed to work on block device with CLVM and fiber-channel.<br><br>We are using a setup similar to yours, with Redhat Cluster Suite and Xen (no libvirt). There is some constraints, but it's working fine and allow live migration.<br><br>Cheers,<br>Nicolas AGIUS<br><br>[1] http://www.opennebula.org/software:ecosystem:cxm_drivers<br><br><br>--- En date de : <b>Jeu 14.2.13, Kapetanakis Giannis <i><bilias@edu.physics.uoc.gr></i></b> a écrit :<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><br>De: Kapetanakis Giannis <bilias@edu.physics.uoc.gr><br>Objet: Re: [one-users] CLVM datastore<br>Ŕ: "Jaime Melis" <jmelis@opennebula.org><br>Cc: "Mihály Héder" <merlin@sztaki.hu>, "Users OpenNebula"
