Can we get LIBVIRT_DEBUG=1 to just dump the SOAP response?

/me checks the source ...

It seems like currently debug output is hard-coded into a #define.
Having it wired to LIBVIRT_DEBUG would allow people to debug these
issues without needing to recompile.

OK, turns out that the VMWare server was in "maintenance mode".

Nothing wrong with it, just a bit unusual.  But as you say, it is a
valid path according to ESX's unusual path convention.

It's so that we can inspect the VM's disk, for virt-inspector:

  http://libguestfs.org/virt-inspector.1.html

Ideally we'd like to download all or part of the VM's disk (ie. VMDK
file(s)).

Thanks for your detailed reply!
