Disable GA serial port in QEMU as it is not used by GA #3148
base: master
Are you sure you want to change the base?
Conversation
GA was switched back to use SSH socket forwarding due to stability issues, but QEMU still exposes the serial as a Unix socket, which is 1) unused 2) removed from FS and replaced with forwarded via SSH This is unnecessary and confusing. Future code changes might introduce a common feature toggle to disable code paths simultaneously in QEMU, HA and GA setup, but for now it at least will make both code paths consistent.

This is minor, but was confusing to me, when I pulled the latest version and tried to run it to understand all the wiring between different processes. |

If the code is not needed lets delete it.

I'm still using it in an on/off manner (with changes in hostagent.go), while working on QEMU support on Windows hosts. So, it is not 100% useless for sure. May be we can just dismiss this PR for now and I will later create some other more prepared with either removal or feature toggle.

Maybe we need an option to enable/disable this?
You can also make this a draft, maybe others will find this change helpful.

The comment is not clear. If it is needed to explain why the code is commented it can be removed with the commented code.
