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

[Yin Olivia-R63875]

Hi,

I'm trying remote connection with qemu hypervisor on FSL PPC board.

The libvirt server is the PPC board.

root at ppc:~# ifconfig eth0 10.193.20.109
root at ppc:~# libvirtd -d
root at ppc:~# virsh -c qemu:///system define test.xml
root at ppc:~# virsh -c qemu:///system start test
root at 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 at x86:~$ virsh -c qemu+ssh://root@10.193.20.109/system list --all

Are you sure you want to continue connecting (yes/no)? yes

I tried to verify the remote connection on localhost. But it also failed as below:

root at mpc8572ds:~# virsh -c qemu+ssh:///root@localhost/system list --all
root at localhost's password:
error: failed to connect to the hypervisor

Could anyone give suggestion on this issue?
