Subject: [PATCH hci-dev v6 0/2] vfio/migration: don't stop the device on guest shutdown #VSTOR-153976
Date: Mon, 9 Nov 2026 22:45:16 +0200 [thread overview]
Message-ID: <20261109204518.220617-1-andrey.drobyshev@virtuozzo.com> (raw)
v5 -> v6, after Sashiko's review:
- patch 2: the device is stopped as before when a migration is running,
not only when it is in a precopy state. A device without precopy
support kept running after a guest shutdown during a migration;
- patch 1: a device that fails to stop is reset, as on a VM stop, so it
is never closed or saved running.
v5: http://lore.virtuozzo.com/qemu/20261109190342.200293-1-andrey.drobyshev@virtuozzo.com/
