I realize you copy/pasted this so it's an optional suggestion as it would require you to update both instances:

Is this just any number we want? For powerVS do they not have fixed instance sizes?
| variable "processors" { | ||
| description = "Number of virtual processors to allocate to the VM" | ||
| default = "15" | ||

15 seems like a random number - would have expected a power of 2 (like 8 or 16) here.

Each server model has a maximum allowable number, which may vary depending on utilization (interesting)
On the e880, the maximum core availability is now 12.04, reduced from the previous 15 I added here.
We now have on the e980, with 31.5. I will add a note in how to check it before ,so we may add the max we can.

Any instructions on how to create that network?

There is the internal docs, since it is for VPC. Not sure it is worth adding a general one here, maybe we won't need to create it without using VCP.

if we ever wanted to do this for FCOS we'd need networks created? Can that be defined in tofu configuration? Let's add a comment somewhere to mention it and that it's a TODO item.

FTR I think our fcos ppc64le server only has 32G of memory so we could probably go down here if that makes sense if the costs are really high.

The description mentions shared/dedicated as options but we have set it to capped?

optional: for systemd_type and proc_type it might be useful to add a hyperlink to a place where there is a description of the options.
