Hi, I'm looking information about using libvirt with san (fiber channel) based storage and googling for a while i don't see anything about it. I send this email in order to get advices about libvirt and shared storage We use here, for 3 years now, 8 linux centos server connected to an hitachi FC SAN (multipath devices). Each server run Xen dom0 and use SAN LUNs to store Virtual machine filesystem ( basically one LUN per VM). For each LUN we create an LVM VolGroup. On each VolGroup we create Logical volumes (one for swap, one for root filesystem). We present to the vm the 2 Logical Volume as it was raw disk. In this system we can make live migration between host using local scripts which assume than one VolumeGroup is used only by one host at the same time on the 8 node "cluster". We don't use any clustered aware environment like CLVM. We plan to migrate to kvm and libvirt with the new centos release (CentOS 6). Reading the upstream documentation and libvirt i don't find anything about using libvirt with san storage except for iscsi. Do you have any link or idea about using kvm + libvirt + SAN FC storage that permit to make live migration between node (we think about RHCS with GFS2 but it seems very complex to set up) ? Do you think i can use the LUN's SAN as local storage on each node. For each LUN create an LVM Volume Group (same on each node, like that we doing now with xen) and use it as volume pool in libvirt. Is volume pool in libvirt is 'cluster aware' (Can i access it simultaneously from different node) ? I'm beginner in kvm so any advice will be great. regards -- Frederic Soulier DSI / Service Système Université Toulouse 1 Capitole 2 rue du doyen Gabriel Marty 31 042 Toulouse Cedex 9 Tel: +33 5 61 63 39 98 Fax: +33 5 61 63 37 98
