The numa_add() code was unconditionally adding 1 to the get_opt_name() return value, making it point after the end of the string if no ',' separator is present. Example of weird behavior caused by the bug: $ qemu-img create -f qcow2 this-file-image-has,cpus=5,mem=1000,in-its-name.qcow2 5G Formatting 'this-file-image-has,cpus=5,mem=1000,in-its-name.qcow2', fmt=qcow2 size=5368709120 encryption=off cluster_size=65536 $ ./x86_64-softmmu/qemu-system-x86_64 -S -monitor stdio -numa node 'this-file-image-has,cpus=5,mem=1000,in-its-name.qcow2' QEMU 1.3.50 monitor - type 'help' for more information (qemu) info numa 1 nodes node 0 cpus: 0 node 0 size: 1000 MB (qemu) This changes the code to nove the pointer only if ',' is found.
