From: Yu Zhang <[email protected]>
In commit 3fa9642ff7 change was made to convert the RDMA backend to
accept MigrateAddress struct. However, the assignment of "host" leads
to data corruption on the target host and the failure of migration.
isock->host = rdma->host;
By allocating the memory explicitly for it with g_strdup_printf(), the
issue is fixed and the migration doesn't fail any more.
