Hi! I've just done a clean CentOS 6.4 install on an iWeb dedicated server and installed OpenVZ and OpenVZ Control Panel.

I created a CT and assigned it an IP, and nameserver, but when I try to ssh that IP it sends me to the Host node instead of the CT (I know that because with the CT root password it says access denied, but with the node password it enters fine for example)

What can I do? I've followed these guides:
openvz dot org/Quick_installation
howtoforge dot com/installing-and-using-openvz-on-centos-6.4

I have 5 IPs in the host machine

Here's the output for "ifconfig" (last ip number masked by me)

I see you have IPs on two different subnets?

Start by detaching all IPs you plan to use for VMs from eth0, except for eth0:0 (for now).

So, you should have no eth0:1, eth0:2, eth0:3. Then simply assign the IP that used to be eth0:1 to your VM and it will work.

In the mean time, search for cases of having IPs from different subnets and go from there - you'll understand why I advised you to keep eth0:0 for now.
