Using qom-list and qom-get to get all the nodes and property values in a QOM tree can take multiple seconds because it requires 1000's of individual QOM requests. Some managers fetch the entire tree or a large subset of it when starting a new VM, and this cost is a substantial fraction of start up time. Define the qom-list-get command, which fetches all the properties and values for a list of paths. This can be much faster than qom-list plus qom-get. When getting an entire QOM tree, I measured a 10x speedup in elapsed time.
