Hi all,
When I create a LXC guest(RHEL5.4) via libvirt, the guest could boot
successfully. I could ping to guest, but can not ssh into the it. The
secure log in the guest shows that this is due to lack of '/dev/tty'
device:
# tail /path/to/rootfs/of/container/var/log/secure
Jul 27 04:25:25 xen2143v sshd[671]: Accepted password for zhangyufang from
10.0.0.1 port 34102 ssh2

for user zhangyufang by (uid=0)

*Jul 27 04:25:25 xen2143v sshd[673]: Received disconnect from 10.0.0.1: 11:

The xml of the guest:

Could anyone point me to where the problem is? Thanks.
Best Regards.
