Re: [libvirt-users] remote connection issue 'virsh -c qemu+ssh:///root@localhost/system list'

Hi Javier, Thanks for your help. From the pages you provided, I guess you suggest is as below: * Cannot recv data: Host key verification failed. : Connection reset by peer Sucede al lanzar: virt-manager -c qemu+ssh://usuario@hipervisor/system Solucion: iniciar una sesion SSH para almacenar las claves del hipervisor en el cliente: ssh usuario@hipervisor Exactly, I've login with ssh and then connect with virsh. user@x86:~$ ssh root(a)10.193.20.109 root(a)10.193.20.109&#39;s password: root@ppc:~# exit logout Connection to 10.193.20.109 closed. user@x86:~$ virsh -c qemu+ssh://root@10.193.20.109/system list --all root(a)10.193.20.109&#39;s password: error: failed to connect to the hypervisor error: End of file while reading data: nc: invalid option -- 'U' BusyBox v1.19.4 (2013-03-08 13:08:18 CST) multi-call binary. Usage: nc [-iN] [-wN] [-l] [-p PORT] [-f FILE|IPADDR PORT] [-e PROG]: Input/output error It still failed to connect the hypervisor, instead of ssh issue.
