Been using OpenVZ for many years and love it. Just works. So - should I upgrade to OpenVZ 7? Only running Linux and wondering ..

What is the migration path?
Is it worth it to migrate?
Any downside to upgrading?

Just like to get an overview of version 7.

Your upgrade path would be to create a new OpenVZ 7 host and migrate any existing containers to it.

Rather than doing it blindly, you are strongly recommended to check out the documentation for 7 here:

https://docs.openvz.org/

In particular, read the Readme to see what's new and known issues and restrictions. Some current significant restrictions include:

- Private networks are not supported.
- Basic firewall is not supported.

For some, those will be a deal breaker until the limitations are overcome.

What exactly does this mean? iptables isn't supported?
What are private networks in this context?

- Private networks are not supported.
- Basic firewall is not supported.

Also I would be interested (like williamt) in details of the private network restriction. Can someone explain or provide a link to the related documentation?

As I read in the documentation, it's only possible to add bridged interfaces to a VE. This is additionally to the host-routed network which is used by a VE by default. Is this the mentioned restriction?
