Hello,
I am trying to set public IP on VPS working uder KVM.
At the begging I would like inform that I didn't met problem with setting public IP for VPS working under openVZ. Problem only exists in KVM.
I am using Virtualizor for dedicated server which I bought in OVH.

In case of openvz I just add public IP address and local IP in vps configuration wizard, under creation moment. It normally works.  My vps is accessible from main host, and from internet via public IP.

In case on KVM it won't works in the same way. Any suggestions how to make it works ?

Hi,

You can check this guide to add ips on panel.

http://www.virtualizor.com/wiki/Setup_OVH

Please follow the guide properly and then you will not face issues with KVM vps.

Note:Ips assigned to  OpenVZ vps will not require mac to be generated.

Use a console to manually set up the IP in the operating system as if it were the host machine.
