For a reason, instance is shutdown, then it never open again. i have some backups, i tried to return previous backups. But they also gave same error. Thanks to replication i could get it back. i copied image from replication site... as i said "qemu-img" command completely unusable on that image. = There should be another mechanism. It blocks everything. = I try to edit header to remove extra data. But i could not find header info= rmation on website. = thanks -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1808928 Title: Bitmap Extra data is not supported Status in QEMU: New Bug description: i am using dirty bitmaps and drive-backup.
