Description David H. Gutteridge 2018-07-31 05:41:42 UTC

Description of problem:
At present, the scrollback buffer size is hard-coded to 1,000 lines in serialcon.py. This can be a problematic limitation when dealing with things like kernel debugging output. It would be helpful to make this a configurable setting.

Version-Release number of selected component (if applicable):
Current on GitHub as of June 12, revision 139031793c953afaac8d38861debbd916f6f4bcb

Thanks for the suggestion. I would take a patch to bump up the default limit. But adding configuration here is not something I want to add UI for because it's fairly niche. If you need full console scrollback you can drop to the command line and use 'virsh console' which integrates with your terminal. I'm afraid if we open the door to terminal config settings inside virt-manager it would be a never ending slippery slope asking for more.
