[libvirt-users] Error facing when starting the VM.

Hi, i am using eucalyptus -2.0.3 and libvirt 1.1.3 for xen -4.2.1. i found this error when starting the Vm via euca2ools(euca-run-instances) the error details are as follows: *libvirt: internal error: client socket is closed (code=1) * *hypervisor failed to start domain* But from virsh i checked everything is working fine. I dont know why the socket is getting closed when accessing from eucalyptus. GIve some suggestions to solve this error. Regards, cooldharma06.
