Clearly command lines that use options added in newer QEMU won't work on older QEMU, but we do make a serious effort to continue to support older commandlines on newer QEMU, even if there is no versioned migration support. Upgrading QEMU and expecting your old configs to keep working is a reasonable user expectation. thanks -- PMM -- libvir-list mailing list libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
