Hi Tomáš,
virsh list --all works locally and results in list of all VMs.
virsh -c xen+ssh://root@192.168.1.40 results in two errors:
error: failed to connect to hypervisor
error: End of file while reading data: : Input/output error
--
Thanks & Regards,
Anantha Raghava

Could you please verify that running 'virsh list --all' localy works too?

That is because your libvirt URI is wrong. It has to be 'xen+ssh://...'
not 'ssh://...'.
Does it work if you try: virsh -c 'xen+ssh://root@192.168.1.40'
Best regards,
Tomas
