Where are the dumpfiles that savevm command produce in qemu?

Question

I'd want to do some migration work with qemu, but met some difficulty. So if I get the dumpfiles that savevm command produce, it might be helpful. Does anyone know where qemu save these files?

Answer 1

To issue the savevm command the file-format of your configured disk must support snapshots, e.g. the command doesn't work if you use the raw file-format, a raw block-device or no disk-device at all.

To answer your question: it is stored as a snapshot inside of your diskimage-file. To view your snapshots issue:

qemu-img snapshot -l mydiskimage.qcow2
