https://bugzilla.redhat.com/show_bug.cgi?id=1191355 When we migrate a vm with migrateuri option with a uri do not have scheme like this: # virsh migrate test4 --live qemu+ssh://lhuang/system --migrateuri 127.0.0.1 target libvirtd will crashed because uri->scheme is NULL in qemuMigrationPrepareDirect this line: if (STRNEQ(uri->scheme, "tcp") && add a value check before this line. Also fix a place like this in doNativeMigrate.
