When QEMU launches it, i think it just inherits stdout/err from QEMU itself, so errors appear mixed into QEMU's stdout output. When libvirt launches it, there stdout is connected to /dev/null and stderr is connected to a pipe which libvirt closes almost immediately. This means any errors are lost as any attempt to write to stderr will get EPIPE :-( Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :|
