hiii Canhua,
lxc-start -n vm2
/usr/lib/lxc/lxc-init is /usr/lib/lxc/lxc-init
sshd is /usr/sbin/sshd
Could not load host key: /etc/ssh/ssh_host_rsa_key
Could not load host key: /etc/ssh/ssh_host_dsa_key
And contents of /etc/ssh are::
ls /etc/ssh/
moduli sshd_config ssh_host_dsa_key.pub ssh_host_rsa_key.pub
ssh_config ssh_host_dsa_key ssh_host_rsa_key
What is problem this time ?????
Regards,
Nishant.
