Is there any chance we can get this merged? I'd love to be able to use go-discover on my Proxmox cluster!

@hashicorp-cla Bot please merge this 😄
thank you!

Jokes aside , any ideas when or if this is going to be merged ?

[prologic]

Yes please! 🙏

[giodamelio]

Just resolved the conflicts.

Is this something that the maintainers of this project would be interested in? Not sure who to tag here, so @mikemorris as the last committer as of the time of writing, you are in luck 😆 .

[aduzsardi]

thank you @giodamelio for your time and effort in adding this feature

👋 We're in a difficult position currently as maintainers currently in that it's not possible for us to validate or test most of the less-common cloud providers that contributors are interested in adding support for - we've discussed an alternative proposed structure to make these lookups more pluggable in hashicorp/consul#9100 and have started some work towards enabling that in a new library that we've recently made public at https://github.com/hashicorp/go-netaddrs, please take a look and let us know if this might work for your needs!
