[libvirt-users] Problem connecting to hypervisor

[Vikas Kokare]

I am trying to establish a connection (using virsh command) to a couple of
hypervisor hosts, both on SLES 11.3 environments. The host from where i am
making both the connections is a SLES 10.4 instance.



*kvmh911351246:~ # virsh -c qemu+ssh://9.113.51.247:22/system
<http://9.113.51.247:22/system>libvir: XML-RPC error : authentication
requirederror: failed to connect to the hypervisor*

The SSH authentication to hypervisor host 9.113.51.247 has already been
established.



*kvmh911351246:~ # ssh root at 9.113.51.247 <root at 9.113.51.247>Last login: Tue
Jun  3 11:31:56 2014 from scm-kvmh2-rhel6SLES11-51-247:~ #*

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 foundlibvir: Remote
error : socket closed unexpectedlyerror: Failed to connect to the
hypervisor*

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-0.5.12-0.7.16libvirt-1.0.5.1-0.7.10libvirt-python-1.0.5.1-0.7.10libvirt-client-32bit-1.0.5.1-0.7.10libvirt-lock-sanlock-1.0.5.1-0.7.10libvirt-client-1.0.5.1-0.7.10*

*9.121.58.19 (SLES 11.3)*



*libvirt-cim-0.5.12-0.7.16libvirt-client-1.0.5.1-0.7.10libvirt-python-1.0.5.1-0.7.10libvirt-1.0.5.1-0.7.10*

*libvirt-python-0.3.3-18.22.1libvirt-devel-0.3.3-18.22.1libvirt-0.3.3-18.22.1*
How can these connection failures be debugged? Is there a way to know more
information about them?
