Best way to migrate VM to CT?

[pc2]

Hello everyone,

we run a 3-node-cluster with a VM, which we want to migrate to a container for performance reasons.
It is important to keep our home directories and network configuration.
Is there a best way to do it?

Thanks!

I would setup the container - and then migrate the data from the VM using `rsync` - then check everything for function and as a last step change the IP from the VM to the container

I hope this helps!

What are your underlying problems? QEMU VMs and containers does have almost identical performance on modern and big systems.

You will loose the feature live migration if you switch to container, are you aware of that?
