+Subject: [PATCH] Avoid exploding if guest refuses to detach a volume
+
+When we run detach_volume(), the guest has to respond to the ACPI
+eject request in order for us to proceed. It may not do this at all
+if the volume is mounted or in-use, or may not by the time we time out
+if lots of dirty data needs flushing. Right now, we let the failure
+exception bubble up to our caller and we log a nasty stack trace, which
+doesn't really convey the reason (and that it's an expected and
+reasonable thing to happen).
+
+Thus, this patch catches that, logs the situation at warning level and
+avoids the trace.
+
