Alejandro , thanks for your words.
Let me explain:
About live migration ... yes I think this is what I need to achieve.
So basically you can "drag and drop" VMs from one node to another ?

Right click the VM -> Migrate -> Choose target node


What do I need to achieve this ? / Only have one node.

You can’t with one node - where are you going to migrate?

My current pve bos is in production with very important machines running on
it.
I will add a second pve server machine soon.
But , I dont have any network storage , so the question would be:
Having two pve machines (already running and fresh one) is it possible to
perform live migrations?
or is it mandatory to have an intermediate hardware or something like that?


Have a look at

https://YourProxmoxServer:8006/pve-docs/chapter-qm.html#qm_migration<https://yourproxmoxserver:8006/pve-docs/chapter-qm.html#qm_migration>

The Help/Docs in your Proxmox node has the information you look for.

Yes you can
You need more than one node, a Proxmox Cluster

An Online/Live migration will take longer if using local storage as it will copy the entire VM across nodes.

Go into the Replication section within your VM and click Help to learn how to reduce the migration times. -> pve-docs/chapter-pvesr.html#chapter_pvesr

Hi guys.
Just wondering if is it possible to move machines without outage ?

I thought at first you were referring to a live-migration which is easy to
achieve

64 bytes from 10.0.0.111: icmp_seq=25 ttl=64 time=0.363 ms
64 bytes from 10.0.0.111: icmp_seq=26 ttl=64 time=0.397 ms
64 bytes from 10.0.0.111: icmp_seq=27 ttl=64 time=0.502 ms
Request timeout for icmp_seq 28
64 bytes from 10.0.0.111: icmp_seq=29 ttl=64 time=0.366 ms
64 bytes from 10.0.0.111: icmp_seq=30 ttl=64 time=0.562 ms
64 bytes from 10.0.0.111: icmp_seq=31 ttl=64 time=0.469 ms

And certainly happens with little to no outage.

What do I need to achieve this ?

More than one node (cluster), storage, then perform a migration… using
storage like Ceph will make the migration way faster.

Currently have only one box ...

And then I got confused. Are you trying to migrate from another hypervisor
or you are just asking if it’s possible at all and then would add another
box?

Thanks.
Leandro.
