There remains this one from the\nprevious series:\n\npseries migration causes a guest hang after migration due to a new\nvariable used to track the stopped state of vcpus, which is not\nmigrated. Fix is to migrate the new variable. To avoid breaking\nbackward migration, a compat property is added. For forward migration,\na heuritics based on the known QEMU code is used.\n\nThanks\n\nCI run: https://gitlab.com/farosas/qemu/-/pipelines/2220496446\n\nv1:\nhttps://lore.kernel.org/r/20250819223905.2247-1-farosas@suse.de\n\nFabiano Rosas (2):\n target/ppc: Fix env->quiesced migration\n tests/functional: Add a OS level migration test for pseries\n\n hw/ppc/spapr.c | 6 +++\n target/ppc/cpu.h | 1 +\n target/ppc/cpu_init.c | 7 +++\n target/ppc/machine.c | 63 ++++++++++++++++++++++++\n tests/functional/ppc64/test_migration.py | 12 +++++\n tests/functional/ppc64/test_pseries.py | 35 +++++++++++++\n 6 files changed, 124 insertions(+)"}
