[Qemu-devel] [PATCH] virtio-serial: propagate guest_connected to the port on post_load |
Date: |

From: Alon Levy <address@hidden>
When migrating a host with with a spice agent running the mouse becomes
non operational after the migration due to the agent state being
inconsistent between the guest and the client.
After migration the spicevmc backend on the destination has never been notified
of the (non 0) guest_connected state. Virtio-serial holds this state
information and migrates it, this patch properly propagates this information
to virtio-console and through that to interested chardev backends.
