From 7f56e740a68c9f4ccebf7ad7590e82fbb30ffc87 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 14 May 2014 17:43:20 +0800 Subject: memory: add error propagation to file-based RAM allocation Right now, -mem-path will fall back to RAM-based allocation in some cases. This should never happen with "-object memory-file", prepare the code by adding correct error propagation. Signed-off-by: Paolo Bonzini Signed-off-by: Hu Tao Acked-by: Michael S.
