Re: [Libvir] Patch: driver->open functions return declined or error status

I want to change the driver->open function so that as well as declining
a name (returning -1 as now), it may also indicate that it accepts the
name, but there is an error opening the name (-2). virConnectOpen fails
in this second case, rather than going on and trying the next driver in
sequence.
This is all sane - I've certainly seen some really odd problems before
from not being able to detect the difference between an operation not
being supported, vs supported but failed. When we merge the Xen drivers
into one those will go away, and thus addresses the open() case, so
I'll commit it unless anyone objects.
