This is a very good example place where libvirt would really benefit from having "stacked" error messages as the low level message doesn't give the user a clue about what happened. > a warning to logs saying "Hey, you've got a corrupted file". > > Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; > --- > src/qemu/qemu_driver.c | 5 ++++- > 1 file changed, 4 insertions(+), 1 deletion(-) I'm NOT ACKing this right away as I personally don't like the change of behavior to report an error in case of a corrupt managed save.
