[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. # virsh version Compiled against library: libvir 0.9.1 Using library: libvir 0.9.1 Using API: QEMU 0.9.1 Running hypervisor: QEMU 0.9.1 # rpm -qa|grep kvm kmod-kvm-83-224.el5.centos.1 kvm-qemu-img-83-224.el5.centos.1 etherboot-zroms-kvm-5.4.4-13.el5.centos kvm-83-224.el5.centos.1 Jingwei Li (lijingwei9060@gmail.com<mailto:lijingwei9060@gmail.com> or lijw@bingosoft.net<mailto:lijw@bingosoft.net>)

I use the newest libvirt, and can not reproduce this problem. Please try the newest libvirt again.
while virsh domblkstat 3 vda, it showed vda rd_req 6667 vda rd_bytes 154084864 vda wr_req 9530 vda wr_bytes 57196544
