The immediate reason for this patch is to reduce the amount of debugging in virt-v2v with using the virt-v2v -v option (because this implies running nbdkit in verbose mode too). Most of the messages are datapath ones about pread/pwrite requests, and in fact as we've added more filters on top of nbdkit these messages have got more and more verbose. However they are not particularly

This creates libnbdkit.so as discussed in the following thread: https://www.redhat.com/archives/libguestfs/2020-March/thread.html#00203 test-delay-shutdown.sh fails for unclear reasons. This series starts by reverting "tests: Don't strand hung nbdkit processes" which is because several other tests fail randomly unless I revert this patch. I didn't investigate this yet so it

This is the previous 5/9 patch posted earlier today, split into reviewable chunks. This passes bisection with -x 'make && make check', but I didn't work very hard on the commit messages, so I refer you back to the original patch to explain how it works: https://www.redhat.com/archives/libguestfs/2020-March/msg00248.html Rich.
