Hi, I am seeing the following error on running the test suite on F10 machines. CIM_NS=root/virt CIM_USER=root CIM_PASS=password ./runtests libvirt-cim -i localhost -c -v KVM -g ComputerSystem -t 41_cs_to_settingdefinestate.py *Starting test suite: libvirt-cim Encountered an error querying libvirt with: virsh -c qemu:///system version. Please check your environment. *This is because the following query does not work with the libvirt on F10: virsh -c qemu:///system version Compiled against library: libvir 0.5.0 libvir: error : this function is not supported by the hypervisor: QEMU error: failed to get the library version The alternate option for this would be to use virsh -c qemu:///system -v 0.5.0 which works for RHEL, F9 and F10. I have modified the main.py for the changes and submitted the patch. But I have one concern, since the version option is listed with the help , it should work even on F10. Should we bring up this to the notice of libvirt folks ? Thanks and Regards, Deepti.
