Subject: [PATCH v1 1/1] vfio: Make migration support non experimental by default.
Date: Mon, 8 Mar 2021 21:39:49 +0530	[thread overview]
Message-ID: <20210308160949.4290-1-targupta@nvidia.com> (raw)

VFIO migration support in QEMU is experimental as of now, which was done to
provide soak time and resolve concerns regarding bit-stream.
But, with the patches discussed in
https://www.mail-archive.com/qemu-devel@nongnu.org/msg784931.html , we have
corrected ordering of saving PCI config space and bit-stream.

So, this patch proposes to make vfio migration support in QEMU to be enabled
by default. Tested by successfully migrating mdev device.
