Does live restore instantly power the VM on?

I'd like to do a live restore (as a new VM alongside the existing) but I don't want the VM to instantly power on.

Before booting I want to change the VLAN it's sat on so that it doesn't conflict with the existing machine.

Is this possible to achieve?

Thanks,
Chris.
 
Hi,
yes, the VM is started right away. It's only possible to change settings like name, core count, memory on the fly when restoring in the UI. It might be possible by manually invoking qm create <ID> --archive <PBS volume ID> --live-restore 1 --net<N> <network settings to override> but best try it with a dummy VM first.
 
For reference, this is tracked here: https://bugzilla.proxmox.com/show_bug.cgi?id=5381

In the meantime, until exposed in the UI, you can use the CLI command.

This could also be a step in the direction of setting up automatic backup testing natively in Proxmox, right? Similar to Veeam's Recovery Orchestrator. Where you can setup automatic restore tests. Honestly, I'd be happy with it just confirming the QEMU agent responds. Veeam gets really complicated with virtual subnets and what not to do workload tests, which I guess is still possible with the SDN, but still.

Automatic tests might be added on top of the following feature: https://bugzilla.proxmox.com/show_bug.cgi?id=5187 Feel free to add your thoughts there.
