Hi everyone.

I have a server with ovh infrastructure. I've been struggling with openvz7 setup and settings for about 2 weeks . I completely installed on Centos 7 operating system.

I created virtual machines with commands, but whatever I do, virtual machines do not enter the internet. There is no explanatory information on the internet.

Before, I installed centos 6 and openvz 6 on my server and managed my server for 4 years with this system, it was really nice and easy.

As bridge systems have changed with Centos 7, I cannot solve it as before. If anyone knows, I would like to ask for help..


IP addresses are examples.


My server ip address: 152.7.209.202
