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:$2 sudo chmod +x /bin/netcatsocket You can try it and see if it helps or not. PD: looping in again the list, I replied just to Olivia before Cheers El 21/03/2013 12:47, "Yin Olivia-R63875" <r63875@freescale.com> escribió:
Hi Javier,
Thanks for your help. From the pages you provided, I guess you suggest is as below: * Cannot recv data: Host key verification failed. : Connection reset by peer
Sucede al lanzar:
virt-manager -c qemu+ssh://usuario@hipervisor/system
Solucion: iniciar una sesion SSH para almacenar las claves del hipervisor en el cliente:
ssh usuario@hipervisor
Exactly, I've login with ssh and then connect with virsh.
user@x86:~$ 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

Hi Olivia.
It's in spanish, but pretty easy to follow, maybe it helps you:
http://wiki.legido.com/doku.php?id=informatica:linux:virtualizacion:kvm#adm
inistrar_kvm_y_vm_desde_una_gui_en_el_cliente
With this guide you should be able to connect from a client machine (for instance your laptop) to the hypervisor (KVM) if both have SSH connectivity.
Cheers.

Hi,
I'm trying remote connection with qemu hypervisor on FSL PPC board.
The libvirt server is the PPC board.
root@ppc:~# ifconfig eth0 10.193.20.109 root@ppc:~# libvirtd -d root@ppc:~# virsh -c qemu:///system define test.xml root@ppc:~# virsh -c qemu:///system start test root@ppc:~# virsh -c qemu:///system list --all Id Name State ---------------------------------------------------- 2 test running
Connect from an X86 PC (Ubuntu 10.04) to the PPC board.
user@x86:~$ virsh -c qemu+ssh://root@10.193.20.109/system list --all The authenticity of host '10.193.20.109 (10.193.20.109)' can't be established. RSA key fingerprint is 2f:56:07:08:da:7d:ac:41:45:57:d2:12:15:19:67:e0. Are you sure you want to continue connecting (yes/no)? yes root@10.193.20.109's password: error: failed to connect to the hypervisor error: End of file while reading data: Warning: Permanently added '10.193.20.109' (RSA) to the list of known hosts. 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
I tried to verify the remote connection on localhost. But it also failed as below:
root@mpc8572ds:~# virsh -c qemu+ssh:///root@localhost/system list --all root@localhost'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
Could anyone give suggestion on this issue?
Best Regards, Olivia
