Hi All

We have been using Proxmox for a number of years and something that's been popping up as an issue for us recently are the VMID starting at 100.

we have been working with using VMID last octet with the last octet of an assigned subnet.

ie vmid "100" IP assigned 192.168.0."100"

the issue that's being faced is that due to the default VMID numbering starting at 100 we can only use 154 addresses per subnet, leaving us with 100 unused IP's and forcing us to use a different subnet.

Is there a way to allow the use of VMID lower than 100?

are we able to reserve some VMID ie 1-20 for internal use and have the remaining VMID available for consumption?

any assistance is greatly appreciated.

You are trying to impose a relationship where there really is none, I would not recommend doing this.

Things are gonna end badly for your scheme and get really confusing if you have to start doing restores.

The vmid is more or less random, the things that matter are the vmname + IP + DNS name. You could keep Templates starting at e.g. 1000 but trying a 1:1 map between vmid and IP is not a good strategy.
