Changelog from v2: --- - Cosmetic fixes, typo in comments (thanks Thomas) - Improve migration prompt when tests are run manually (thanks Thomas) - Whitespace fixes This series depends on my SIGP store additional status series to have access to the guarded-storage and vector related defines ("[kvm-unit-tests PATCH v3 0/2] s390x: Add tests for SIGP store adtl status"). Add migration test support for s390x. arm and powerpc already support basic migration tests. If a test is in the migration group, it can print "migrate" on its console. This will cause it to be migrated to a new QEMU instance. When migration is finished, the test will be able to read a newline from its standard input. We need the following pieces for this to work under s390x: * read support for the sclp console. This can be very basic, it doesn't even have to read anything useful, we just need to know something happened on the console. * s390/run adjustments to call the migration helper script. This series adds basic migration tests for s390x, which I plan to extend further.
