[libvirt] [PATCH] qemu: fix crash in migrate when migrateuri do not have a scheme
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.
