[PATCH] hw/intc: fix the issue of vNMI not supporting live migration
by Jinqian Yang 21 Nov '25

21 Nov '25

GICD_INMIRn marks SPI as NMI. GICR_INMIR0 marks SGI and PPI as NMI. If GICR_INMIR0 or GICD_INMIRn is not migrated, the vNMI state will be lost on the destination side. Additionally, use a subsection to avoid migration failure when the remote QEMU does not have GICR_INMIR0 support. When migrating from a QEMU that saves GICR_INMIR0 or GICD_INMIRn state to one that does not, the migration will fail with a graceful error message. When migrating from a QEMU that does not save GICR_INMIR0 or GICD_INMIRn state to one that does, the migration will succeed, but the vNMI state will be lost on the destination side since the source did not save it.

[PATCH] hw/vfio/migration: Fix vfio migration isn't aborted in a corner case
by Jinqian Yang 28 Sep '25

28 Sep '25

From: Kunkun Jiang <jiangkunkun(a)huawei.com> In the final stage of vfio migration, the destination VM will execute vm_start vfio_vmstate_change vfio_migration_set_state At this time, vfio_migration_set_state may return failure. For example, the device is in the reset process due to some hardware problems. In this case, the vfio migration should be aborted, but the current logic does not abort. Instead, it continues to execute, which will cause Unpredictable impact. This patch fixes this case.
