the problem is still exist on RHEL5.3 machine.and 'virsh domblkstat' works for
xen PV block devices,but FV fail.
(kernel:2.6.18-128.1.6.el5xen;libvirt-0.6.2-1.el5)

for PV:
[root at dhcp-66-70-18 /]# virsh domblkstat test xvda
xvda rd_req 5539
xvda rd_bytes 153436160
xvda wr_req 1289
xvda wr_bytes 9679872
xvda errs 0

for FV:
[root at dhcp-66-70-18 domain]# virsh domblkstat test hda
error: Failed to get block stats test hda
error: internal error read_bd_stats: Frontend block device not connected
