And even more importantly, once we get the error reporting patches integrated
into libxc, having the xc_linux_save/restore calls made by XenD directly
would ensure we get reliable error handling for save/restore operations.
It used to work that way. xc_linux_save/restore were factored out of
Xend late in the 3.0 dev process. I believe the idea was that they
should be executed with lower privileges (which is why they take file
descriptors as command line arguments instead of just calling
xc_interface_open() like you would expect).
I believe it was Christian who was driving this. Perhaps he has a few
more details?

So, is there any good reason for xc_save & xc_restore to exist as separate
processes - it just seems like a huge complication to me, increasing
fragility of the system & reducing the quality of error reporting we can
get

Dan.
