[Qemu-devel] [PATCH 0/3] Fix migration problems of s390x guests on Sparc hosts

Posted by Thomas Huth 5 years, 6 months ago

The new migration test uncovered some alignment problems in the s390x
code:

https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg03012.html

Here are some patches to fix these issues (only tested with
clang and -fsanitize=undefined, since I do not have access to
a Sparc machine, but I hope that covers the issues there, too).
