Eduardo,

Thanks for the help! I encounter an issue when trying to connect the 
remote VIOS/IVM server:

1. The used virsh is built from 0.9.12 source code with ./configure 
--prefix=/usr --with-phyp; make; make install;

2. When I try to connect the VIOS server with ssh, it succeeds with 
output looks like:
     root at dennis-:/home/libvirt-0.9.12# ssh padmin at 10.30.56.60
     padmin at 172.30.56.60's password:
     Last unsuccessful login: Wed Jul  4 21:22:22 CDT 2012 on ssh from 
10.16.10.94
     Last login: Wed Jul  4 21:23:14 CDT 2012 on /dev/pts/1 from 10.16.10.94
     [vios:/home/padmin]

3. My virsh runs in the local ubuntu 12.04 system, and I've executed the 
following command:
     sudo usermod -G libvirtd -a padmin

4. When I try connect the VIOS server with virsh, issue occurs:

     root at dennis-:/home/libvirt-0.9.12# virsh -c phyp://padmin@10.30.56.60
     Enter padmin's password for 10.30.56.60:
     error: An error occurred, but the cause is unknown
     error: failed to connect to the hypervisor

     root at dennis-:/home/libvirt-0.9.12# virsh -c 
phyp+ssh://padmin@10.30.56.60
     padmin at 10.30.56.60's password:
     error: End of file while reading data: bash: sh: command not found: 
Input/output error
     error: failed to connect to the hypervisor

     some times the last command also shows error message like:
     root at dennis-:/home/libvirt-0.9.12# virsh -c 
phyp+ssh://padmin@10.30.56.60
     padmin at 10.30.56.60's password:
     error: Cannot recv data: bash: sh: command not found: Connection 
reset by peer
     error: failed to connect to the hypervisor

Is there any tips about this?

BRs,
Dennis
