[Users] Access libvirt/virsh on oVirt node

Hi, how can I access libvirt/virsh on oVirt node? What are the credentials for accessing libvirt/virsh on the command line of a oVirt node? virsh # list Please enter your authentication name: Please enter your password: error: Failed to reconnect to the hypervisor error: no valid connection error: authentication failed: Failed to step SASL negotiation: -1 (SASL(-1): generic failure: All-whitespace username.) It would make debugging things much easier... Thanks - Frank
