[[pvecm_next_id_range]]
Guest VMID Auto-Selection
------------------------
When creating new guests the web interface will ask the backend for a free VMID
automatically. The default range for searching is `100` to `1000000` (lower
than the maximal allowed VMID enforced by the schema).
Sometimes admins either want to allocate new VMIDs in a separate range, for
example to easily separate temporary VMs with ones that choose a VMID manually.
Other times its just desired to provided a stable length VMID, for which
setting the lower boundary to, for example, `100000` gives much more room for.
To accommodate this use case one can set either lower, upper or both boundaries
via the `datacenter.cfg` configuration file, which can be edited in the web
interface under 'Datacenter' -> 'Options'.
NOTE: The range is only used for the next-id API call, so it isn't a hard
limit.
