[Xen-users] NFS access for domU

["Matthew Law" <matt@xxxxxxxxxxxxxxxxxx>]

I know similar questions to this have been asked on here before, but I
just want to check this scheme is sane before I implement it?

I have several dom0's each with 4 x NICs; 2 x NICs in a bond on the public
VLAN for internet access (the dom0 bridge) and 2 x NICs in a bond on the
management & storage VLAN with access to the storage servers.

I want to provide space on a new FreeBSD NFS filer for each of my domUs. 
I can either create individual NFS shares per domU or a single NFS share
with sub-dirs for each domU.  My favoured plan at the moment is to create
individual NFS shares per domU and add them as supplementary disks in the
domU config, something like this maybe:

disk = ['nfs:my.filer.address//domUbackup/domUname.img,xvdb,w']

Is this sane?  Do I have to use a file-based disk image for NFS or can I
use an LVM volume as I do for domU local storage? - the volume would never
be accessed concurrenly by multiple servers, so I don't need any cluster
aware file system on it.


Thanks as always,

Matt.
