Hi Olivia.

Another think that you should check is socat package.

In my documented example the hypervisor running KVM is a Debian squeeze, and I had to proceed this way:

sudo aptitude update; sudo aptitude install netcat socat -R

sudo vim /bin/netcatsocket

#!/bin/bash
socat - unix-client:$2

sudo chmod +x /bin/netcatsocket

You can try it and see if it helps or not.

PD: looping in again the list, I replied just to Olivia before

Cheers

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@10.193.20.109
root@10.193.20.109'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@10.193.20.109'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.

Best Regards,
Olivia
