I think shared storage is the correct solution. If you want the feature,
you'll have to provide the shared storage which is not difficult to do,
otherwise current local storage works ok.
This would keep things as simple as possible, which is quite good for
reliable logs.

Note: as mentioned earlier, the rsync approach does not work for HA, because
you cannot sync the logs for a dead node.

Thought a bit more about that, and I think the only real solution is to but the
VM task logs on
Migrate the VM then migrate the logs for that VM.
Or use some sort of central logging system/distributed database.
A distributed NoSQL database seems like a good place to store the task
logs, each task can simply be a document.
Three ways to deal with task logs when a VM is deleted:
a) never reuse

No, you cannot put large files there! (Everything is stored in RAM!)

We *could* put them in /etc/pve someplace, so they automatically sync

Hi,
i have asked this question already in the past but didn't had the time
to proceed.
I'm still missing that in case of a migration the task history migrates too.
I really like to know the history of a VM and would like to be able to
see it after migration too.
Another problem to me is, that t
