Keep ID argument #41
Keep ID argument #41
Conversation
get_vmids() is split out of get_free_vmid(), to make it common for new check_vmid_free(). check_vmid_free() checks the availability of a vm id. get_free_vmid() would not use any free IDs before the lowest ID. The length to ID diff was replaced/refactored for readability.

Thanks for the PR.
Also refactored the get_vmids() function while splitting it, as it had a bug, not using valid VM IDs (>= 100 < FIRST_USED_ID).
I'm sorry, I don't parse that sentence. But I see there is indeed a bug in that it will never hand out IDs below the first existing ID.
Could you split this up into 2 commits:
- fixing the bug / refactoring / splitting
- adding keep-id

Too late to raise PrepareErrors here. This should've been checked in move_vm() (also done in dry-run).
Here we can safely assume the ID is free and let Proxmox handle duplicate VM id errors.

What would be a nice extension to this patch would be a way to specify a new base id for migrated VMs. (which for a single move would be a way to specify the new ID for the VM) |

@engelant: will you be working on this? |

@wdoekes : Sorry, but I don't hava a dev environment of two proxmox instances anymore. This was the patch I used for myself at the given time to transfer a server. |

I understand 👍 |
Added an argument for preserving the source ID of the VM if possible.
Raises an error if ID is already in use.
Also refactored the get_vmids() function while splitting it, as it had a bug, not using valid VM IDs (>= 100 < FIRST_USED_ID).
