[Xen-users] [XCP] Virtualising the local storage

["msgbox450@xxxxxxxxx" <msgbox450@xxxxxxxxx>]

Has anyone had any real-world experience using a VM to host storage for other VMs. For example, glusterfs running in a VM in domU on host A, replicating to another glusterfs VM on host B, with other VMs on those same hosts connecting to the glusterfs for their storage?

It's obviously not a very efficient way of doing things, but it might be an easy and flexible way to manage things in a scalable way where you can start with just 1 box and end up with 10. I'd be interested to hear if the theoretical performance and reliability concerns are a problem in practice.
