Re: [Xen-users] Can guests share an FC HBA?

["lists@xxxxxxxxxxxx" <lists@xxxxxxxxxxxx>]

Nick mentioned that the host can share it's drives/storage so this has made me 
wonder about something.

In my testing so far, each guest usually has NFS mounts to a central storage. I 
don't know the NFS protocol well so am only guessing that such a connection 
means chatter on the network.

So, if there are say 10 guests on a server, each connected to the shared 
storage via NFS, this would end up being a ton more Ethernet chatter than it 
would if I could simply connect the storage ONCE to the host, then give each 
guess access to this.

Make sense?
