Venumadhav Josyula asked:

I am seeing error connecting when I try to connect for conversion of xen-vm to kvm.

I am use virt-manager w/o problems.

Errors seen:

My answer:


Libvirt is trying to start netcat on the remote system, but it is not installed.

This is shown by the error returned from the remote system:

libvirt: XML-RPC error : End of file while reading data: sh: nc: command not found: Input/output error

To fix the problem, install netcat on the remote system.
