[libvirt] virsh nodedev-dempxml is not supported by the connection driver

Hi,

I meet a problem when I use the command "virsh nodedev-dumpxml pci_0000_00_19_0",it shows as follows:

root shahe26:~# virsh nodedev-list
error: Failed to count node devices
error: this function is not supported by the connection driver: virNodeNumOfDevices

root shahe26:~# virsh nodedev-dumpxml pci_0000_00_19_0
error: Could not find matching device 'pci_0000_00_19_0'
error: this function is not supported by the connection driver: virNodeDeviceLookupByName

root shahe26:~# virsh -version
0.9.0
root shahe26:~# virsh net-list
Name                 State      Autostart
-----------------------------------------
default              active     yes       
root shahe26:~# virsh list
 Id Name                 State
----------------------------------
root shahe26:~# 

I find that only the command "virsh nodedev-? ***" can't work . How can I solve this problem ? thanks.

best regards,
qinguan
