Hi, Patch1: fixed an error restore path when virtio-mem is configured. Patch2: fixed assert failure on error restore path, this issue happens no matter if virtio-mem is configured. Some trick is played to trigger the error path, see https://github.com/yiliu1765/qemu/commit/494d19e7f7242dbc47d7f236937cde0c396a4a7c
Patch3-4: issue only happens with two or more VFIO devices, no issue if only one VFIO device. Patch5: fix a bug that impact "query-balloon" execution Patch6: SIGSEGV if I send "query-balloon" to source qmp monitor, I'm not quite sure if it's deserved to be fixed, as guest has been migrated to destination, it's not a big issue for source qemu to SIGSEGV? Thanks Zhenzhong Changelog: v2: - minor polishment to commit log (Steve) - keep kvm_state so "query-balloon" could work after CPR-transfer (Markus) - add a fix which is found during "query-balloon" execution - rebased to master Zhenzhong Duan (6): vfio/container: Remap only populated parts in a section vfio/cpr-legacy: drop an erroneous assert vfio/iommufd: Set cpr.ioas_id on source side for CPR transfer vfio/iommufd: Restore vbasedev's reference to hwpt after CPR transfer accel/kvm: Fix an erroneous check on coalesced_mmio_ring accel/kvm: Fix SIGSEGV when execute "query-balloon" after CPR transfer include/hw/vfio/vfio-cpr.h | 2 +- accel/kvm/kvm-all.c | 14 ++++++-------- hw/vfio/cpr-legacy.c | 22 +++++++++++++++------- hw/vfio/iommufd.c | 8 ++++---- hw/vfio/listener.c | 4 ++-- 5 files changed, 28 insertions(+), 22 deletions(-) -- 2.47.1
