From: Kevin Wolf Date: Fri, 19 Feb 2016 15:48:10 +0000 (+0100) Subject: block: Fix -incoming with snapshot=on X-Git-Tag: TizenStudio_2.0_p2.4~27^2~6^2~8^2~172^2~27 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=12d5ee3a7e83a42ba75a79b220a9db4dacd70a6e;p=sdk%2Femulator%2Fqemu.git block: Fix -incoming with snapshot=on The BDRV_O_INACTIVE flag should only be set for images explicitly opened by the user. snapshot=on needs to create a new qcow2 image and write some metadata to it. This is not a problem because it can't come from the source, so there's no reason to mark it as BDRV_O_INACTIVE, even though it is opened while waiting for the migration to complete. This fixes an assertion failure when -incoming and snapshot=on are combined.
