Currently, when somebody wants to debug the NSS plugin, they have

The difference between DEBUG() and ERROR() macros is that the
latter also prints (stringified) errno. Inside of findLease()

indicate the error.

I've been debugging a problem with NSS plugin recently [1] and the fact
that I had to recompile libvirt just to enable debugging printings for
the NSS plugin turned out very inconvenient. Make the debug printings
env var dependant and add a few more printings.

Using lsilogic on RISC-V was never an actual decision, but
rather a consequence of that being the default for legacy x86
guests. Using virtio-scsi is a much more sensible choice.

Make the helper stateless. This requires the caller to check
whether it needs to be called in the first place instead of
adding this check inside the function, which makes for more
