Since you are using SLES, it would be best to enter a support ticket with SUSE. > > /kvmh911351246:~ # virsh -c qemu+ssh://9.113.51.247:22/system > <http://9.113.51.247:22/system> > libvir: XML-RPC error : *authentication required* > error: failed to connect to the hypervisor/ > / > / > The SSH authentication to hypervisor host 9.113.51.247 has already > been established. > > /kvmh911351246:~ # *ssh root@9.113.51.247 <mailto:root@9.113.51.247>* > Last login: Tue Jun 3 11:31:56 2014 from scm-kvmh2-rhel6 > SLES11-51-247:~ #/ > / > / > Hence the cause of the authentication failure is not clear. > > The second connection to another SLES 11.3 host looks like > / > virsh # connect qemu+ssh://9.121.58.19:22/system > <http://9.121.58.19:22/system> > *bash: socat: command not found > libvir: Remote error : socket closed unexpectedly > *error: Failed to connect to the hypervisor/ You could try installing socat on the SLES11 SP3 systems. > > where the cause of the error is entirely different. > > The libvirt packages available on these environments are > > *9.113.51.247 (SLES 11.3)* > /libvirt-cim-0.5.12-0.7.16 > libvirt-1.0.5.1-0.7.10 > libvirt-python-1.0.5.1-0.7.10 > libvirt-client-32bit-1.0.5.1-0.7.10 > libvirt-lock-sanlock-1.0.5.1-0.7.10 > libvirt-client-1.0.5.1-0.7.10/ > > *9.121.58.19 (SLES 11.3)* > /libvirt-cim-0.5.12-0.7.16 > libvirt-client-1.0.5.1-0.7.10 > libvirt-python-1.0.5.1-0.7.10 > libvirt-1.0.5.1-0.7.10/ The libvirt packages on your SLES11 SP3 machines are quite old and need updated.
