From 6c7d390b993c4bbadd51ceeb41f7d2fdd68cb4fd Mon Sep 17 00:00:00 2001 From: Jeff Cody Date: Tue, 7 Nov 2017 08:10:34 -0500 Subject: [PATCH] block/parallels: Do not update header or truncate image when INMIGRATE If we write or modify the image file while the QEMU run state is INMIGRATE, then the BDRV_O_INACTIVE BDS flag is set. This will cause an assert, since the image is marked inactive. Make sure we obey this flag.
