+qemu versions 2.10 and 2.11 have error during migration of larger guests

+== Comment: #0 - Christian Borntraeger  - 2018-06-28 06:39:27 ==
+Migration fails with larger guests (e.g. 10GB)  on a z system prints an error message in the log

+This messes up guest state for the CMMA values (guest data corruption)

+    s390x: fix storage attributes migration for non-small guests
+    
+    Fix storage attribute migration so that it does not fail for guests
+    with more than a few GB of RAM.
+    With such guests, the index in the buffer would go out of bounds,
+    usually by large amounts, thus receiving -EFAULT from the kernel.
+    Migration itself would be successful, but storage attributes would then
+    not be migrated completely.
+    
+    This patch fixes the out of bounds access, and thus migration of all
+    storage attributes when the guest have large amounts of memory.

+This fix is part of 2.11.1 so the qemu in bionic is fine.
+The qemu in artful, as well as the qemu in the cloud archives for 16.04 need this fix, so we have
+affected qemus in 17.10 and 16.04. 
+
+Regarding 16.04:
+The bug only triggers for host kernels >= 4.13 - in other words when you combine HWE kernel with the qemu from the cloud archive.
+
+As discussed on IRC, this isn't important for the last week of Artful before EOL.
+But it is for the Cloud Archives longer time I'd think.
+
+So I added a UCA task for them to take a look.
+
