HDFS is not a normal file system. Instead highly optimized for running
map-reduce. As such, it uses replicated storage but imposes a write-once
model on files.
This probably makes it unsuitable as a primary storage for VM's.
What you need is either a conventional networked storage device or if
Hadoop-like capabilities are important then something like MapR which allows
complete NFS access to the file system while still being compatible with
Hadoop for running map-reduce programs.

What do you mean by run Xen server in HDFS? Do you mean you want to use
Xen to allocate data nodes?
