[libvirt] XML support for arbitrary command line arguments

[Harsh Bora]

If I am not wrong, we are not reinventing the wheel, in fact we are 
asking to support the 'invention' of an efficient means of accessing the 
underlying storage on same physical machine. The question is, why to 
take a (virtual) long route through network based protocols which will 
involve overheads required for network communication when we know that 
the required information (folder to share/mount) is on the same physical 
machine.

Moreover, let the user decide on the 'policy' whether he wants to use 
NFS, CIFS or VirtFS (kind of virtualization aware filesystem) and we 
shall only provide the 'mechanism' to do the needful.

regards,
Harsh
