If you've got a working build of libguestfs from git, please try
this and see if it fails for you:
while make -C tests/guests clean windows.img \
LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1 >& /tmp/log ; \
do echo -n . ; done
For me it fails after ~ 100 iterations in a VM. (Unfortunately it
seems to happen all the time in Koji). It doesn't appear to fail on
baremetal at all, but most likely that's because it runs "too
fast" to
show up the race.
You can see the error here:
https://kojipkgs.fedoraproject.org//work/tasks/6637/7316637/build.log
(look for: "/dev/sda1: No such file or directory")
Compare to the code that is running:
https://github.com/libguestfs/libguestfs/blob/master/tests/guests/guest-aux/make-windows-img.sh#L43
It's a bit of mystery why this happens repeatedly for this
make-windows-img script but never anywhere else.
