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

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(a)10.193.20.109's password:

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:

Could anyone give suggestion on this issue?
Best Regards,

You're using busybox's nc (netcat) implementation. It does not support
UNIX sockets which is a requirement of libvirt when using the
qemu+ssh:// scheme to connect.
I'd suggest looking into generating some certificates and using
qemu+tls:// (the default when using qemu:// to a remote system). If
you don't care about any authentication or encryption for testing
purposes you can use qemu+tcp://
