How to reset a VM ?

[hoh]

I was also thinking that you maybe want to reset the vm from the interface as well. I can imaging it can get stuck at times and then it’s nice that you can reset it from the interface. Or is that too grazy?

My understanding is that resetting a VM can mean two different things:

• shutting down one or all running instances of the VM so they will have to reboot
• replacing the mutable volumes by new empty ones

From a technical point of view, I see two ways to achieve these:

1. Aleph messages

By sending a new version of the Aleph program. The VM executor already implements the requirements to achieve this. In terms of UX, Aleph-Account and Aleph-Client CLI could include tools that make this operation easier. The generated actions would not be logged as Aleph messages.

2. Signed Pub/Sub

By sending a signed message to the VM executor on a separate channel. This could for example be a dedicated IPFS pub/sub channel. In terms of UX, Aleph-Account and Aleph-Client CLI could include tools that make this operation easier. The generated actions would not be logged as Aleph messages.
