[libvirt] does libvirt get disk->info.alias, when attaching a disk by virDomainAttachDevice?



Hi,

         I am using libvirt 0.9.1 on CentOS 5.5 64bit ,

         Created a vm :virsh create libvirt.xml

         Attached a disk ,virsh attach-disk 3 /opt/vms/test.img  vdb

         When  getting blosk stats ,virsh domblkstats 3 vdb ,it showed

                 error: Failed to get block stats 3 vdb

error: internal error missing disk device alias name for vdb

while virsh domblkstat 3 vda, it showed

         vda rd_req 6667

vda rd_bytes 154084864

vda wr_req 9530

vda wr_bytes 57196544

 

         I guess libvirt does not get disk->info.alias  when attaching a disk,so it can not get block status.
