block: add native support for NFS
This patch adds native support for accessing images on NFS
shares without the requirement to actually mount the entire
NFS share on the host.
NFS Images can simply be specified by an url of the form:
nfs://<host>/<export>/<filename>[?param=value[¶m2=value2[&...]]]
For example:
qemu-img create -f qcow2 nfs://10.0.0.1/qemu-images/test.qcow2
You need LibNFS from Ronnie Sahlberg available at:
git://github.com/sahlberg/libnfs.git
for this to work.
During configure it is automatically probed for libnfs and support
is enabled on-the-fly. You can forbid or enforce libnfs support
with --disable-libnfs or --enable-libnfs respectively.
Due to NFS restrictions you might need to execute your binaries
as root, allow them to open priviledged ports (<1024) or specify
insecure option on the NFS server.
For additional information on ROOT vs. non-ROOT operation and URL
format + parameters see:
https://raw.github.com/sahlberg/libnfs/master/README
Supported by qemu are the uid, gid and tcp-syncnt URL parameters.
LibNFS currently support NFS version 3 only.
