[Qemu-devel] [PATCH v1 1/1] s390x: fix storage attributes migration for non-small guests |
Date: |
Mon, 15 Jan 2018 17:52:02 +0100 |
Fix storage attribute migration so that it does not fail for guests
with more than a few GB of RAM. Migration itself was successful, but
storage attributes were not migrated completely.
This patch fixes the migration of all storage attributes, even when the
guest have large amounts of memory.
