Subject: [RFC PATCH v2 0/1] Live migration for VIRTIO
Hi all, This patch will describe the needed updates to the virtio specification for adding live migration support for various devices. Live migration is one of the most important features of virtualization and virtio devices are oftenly found in virtual environments so setting a standard mechanism for this feature will allow virtio providers to develop compliant devices that will use standard drivers for that matter. In this solution, that is aimed for VIRTIO PCI devices, the PF is the management entity for migrating its VFs. The communication channel between the migration software, that is running on the host, and the PF controller is the admin control queue. Using this virtq, the migration software will be able to manage the migration process (e.g. track dirty pages, change operational states, save/restore internal context, and more). This initial draft describes the entire solution and later on we'll be able to divide it to smaller pieces and incrementally patch the .tex files. changes from v1: - Subscribed to virtio mailing list (no changes in the content) Max Gurtovoy (1): live_migration: initial support for migrating virtio devices virtio-live-migration.md | 399 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 399 insertions(+) create mode 100644 virtio-live-migration.md -- 2.21.0
