[pve-devel] [PATCH manager 1/2] close #4369: api: optionally only suggest unique IDs

[Dietmar Maurer]

The format of the used_vmids.list is simply, but can lead to
a very large file over time (we want to avoid large files on /etc/pev/).

>    PVE::Cluster::cfs_write_file('used_vmids.list', join("\n", @$vmid_list));

A future version could compress that list, by using integer ranges,
for example:

---used_vmids.list---
100-10005
10007-20000
---------------------

I guess this would be simple to implement...
