Re: [libvirt] [PATCHv2 49/62] qemu: monitor: Add APIs for refreshing disk capacity when using -blockdev

Disk image size data are not contained in the reply of query-blockstats but need to be gathered from query-block. For use with -blockdev we really need to call 'query-named-block-nodes' and process it to retrieve the correct data. This patch introduces qemuMonitorBlockStatsUpdateCapacityBlockdev which updates the capacity data by nodename rather than device name.
