[libvirt] Ask for help about libvirt error: this function is not supported by the connection driver..

[Feng Dan Liu]

Hi,

I'm a libvirt user, I encountered a problem when I use the libvirt java 
bindings, could you please help me take a look？ Thanks in advance! Any 
suggestions from anyone of you will be very appreciated.

Here is my scenario:

Remote access machine A is a RHEL 5.4 workstation with the command "virsh 
version" results:
Compiled against library: libvir 0.8.1
Using library: libvir 0.8.1
Using API: Xen 3.0.1
Running hypervisor: Xen 3.1.0

Hypervisor machine B is a Fedora Core 14 Linux workstation with the 
command "virsh version" results:
Compiled against library: libvir 0.8.3
Using library: libvir 0.8.3
Using API: QEMU 0.8.3
Running hypervisor: QEMU 0.13.0

I finished the code using libvirt java bindings and run it on machine A, 
try to remote connect to the hypervisor on machine B. It can be connected 
succussfully, but when the code calls the function of 
conn.listDefinedStoragePools() or conn.listStoragePools, the libvirt on 
machine B will get the errors below:

04:19:10.467: error : phypStorageOpen:3884 : invalid argument in 
phypStorageOpen: unsupported flags (0x1)
04:19:11.354: warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit 
status '1', qemu probably failed
04:19:12.128: error : virLibConnError:448 : this function is not supported 
by the connection driver: virConnectNumOfStoragePools

With the errors above, my code can't run the functions of 
conn.listDefinedStoragePools() or conn.listStoragePools successfully. 

Could you please give me some suggestions? 

By the way, I try to use the libvirt java bindings 0.3.2 and 0.4.6, both 
of them have this problem.
