[Qemu-devel] [PATCH 5/6] rdma: Fix block during rdma migration


From: Juan Quintela
Subject: [Qemu-devel] [PATCH 5/6] rdma: Fix block during rdma migration
Date: Mon, 16 Jun 2014 05:15:38 +0200

From: Gonglei <address@hidden>

If the networking break or there's something wrong with rdma
device(ib0 with no IP) during rdma migration, the main_loop of
qemu will be blocked in rdma_destroy_id. I add rdma_ack_cm_event
to fix this bug.
