Subject: Re: [acrn-users] Setting up ACRN on a new board with Apollo Lake
SOS console/terminal can't be opened at all; the window actually opens but it says
"There was an error creating a child process for this terminal. Failed to open PTY: Permission denied" and we
can't do anything. It is the same if we use launcher on the left side on the screen, or ctrl+alt+t. Also ssh doesn't work (as well as networking in general) so we can't connect remotely either.
[Geoffroy] A few questions and one suggestion:
* Have you tried to start the ACRN hypervisor with “uart=disabled”? (see
https://projectacrn.github.io/latest/getting-started/apl-nuc.html#add-the-acrn-hypervisor-to-the-efi-partition). A quick test if you have an EFI shell on your platform is to run “acrn.efi uart=disabled” from it.
* Does SSH work when you are not running in the hypervisor?
* Which user are you using when trying to connect over SSH? (note that root is blocked by default)
* When you say “networking is not working in general”, does that mean you are not even getting an IP address?

[Geoffroy] Is the date always off by three days (regardless of whether you’re running in the hypervisor or not)? I don’t know if that is the cause but dates
in the past can cause problems with certificates (and hence something to look at as a potential issue related to SSH).
I don't see why the console would have anything to do with the hypervisor, but simply it doesn't work with it, and works without it, so it's a symptom of some problem.
These all work when not running with the hypervisor.

We checked the log you shared and didn't see anything unusual. We had
one issue which could make serial console use polling mode. I suspected
you hit that issue. But from the interrupt info, everything is fine (
there will be irq flooding if we hit that issue).We need more info.
When you say "Terminal no longer work", do you mean the SOS console
can't work any more? Or it could work for a while and then can't work?
