c
is this on 1.7?
q
1.7.0
👀 1
c
q
I tried commenting out those and kill -HUPign and it didn't seem to help much
i can't tell if i lose my world when i restart rancher desktop
c
ha, I was going to suggest that 🤔
q
Copy code
lima-rancher-desktop:/home/jsoref.linux# grep tty /etc/inittab
# Set up a couple of getty's
#tty1::respawn:/sbin/getty 38400 tty1
#tty2::respawn:/sbin/getty 38400 tty2
#tty3::respawn:/sbin/getty 38400 tty3
#tty4::respawn:/sbin/getty 38400 tty4
#tty5::respawn:/sbin/getty 38400 tty5
#tty6::respawn:/sbin/getty 38400 tty6
# Put a getty on the serial port
#ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100
ttyAMA0::respawn:/sbin/getty -L 0 ttyAMA0 vt100
#ttyS0::respawn:/sbin/getty -L 0 ttyS0 vt100
(I know one is uncommented, but you can see that the output specifies something that doesn't match the uncommented entry)
c
Also, how do you think I can get into that state? I can’t see those messages on my end 😐
q
Copy code
tail -f /var/log/messages
c
not there for me 🤷
q
hmm
i have some proxy lines that i tried to put in /etc/conf.d/docker
lemme remove them and see if that changes things
👍 1
otherwise, i don't think i have anything exciting
c
I wonder if it’s worth removing it and see if you see the logs again
q
i added 
strace
and 
tcpdump
to do some debugging...
none of these feel like good candidates 🙂 -- i'm on an m1 if that matters
c
oh, that might be the candidate I think
I’m on 
x86_64
intel
q
Linux lima-rancher-desktop 5.15.78-0-virt #1-Alpine SMP Fri, 11 Nov 2022 101945 +0000 aarch64 Linux
c
Let me get someone with an M1 machine to see if they can see those errs maybe?!
q
so, restarted w/ those commented out -- still happens
c
just curious if anything interesting in the kernel logs? 
dmesg
?
@fast-garage-66093 are you on a 
M1
machine? can you check if you see the logs mentioned above in 
/var/log/messages
I can’t see them on my machine, I’m wondering if it’s 
arch
specific issue that we might be seeing here.
f
I get these 3 lines every 10 seconds, but that's it:
Copy code
Mar  2 18:44:28 alpine <http://daemon.info|daemon.info> init: process '/sbin/getty -L 0 ttyS0 vt100' (pid 5939) exited. Scheduling for restart.
Mar  2 18:44:29 alpine <http://daemon.info|daemon.info> init: starting pid 5953, tty '/dev/ttyS0': '/sbin/getty -L 0 ttyS0 vt100'
Mar  2 18:44:29 alpine auth.err getty[5953]: tcgetattr: I/O error^M
q
@calm-sugar-3169 so, sounds like it's an aarch thing 🙂
c
yeah, those logs are the issue
f
I thought this was about the guest agent, wasn't it?
I don't get any guest-agent logs in there
c
it’s more of an alpine issue than guest agent I think
q
I'm only really complaining about the getty / tcgetattr i/o errors
c
the only error I see in Josh’s logs are 
Mar  2 18:44:29 alpine auth.err getty[5953]: tcgetattr: I/O error^M
everything else is 
info
or 
warn
q
@calm-sugar-3169 that it's constantly restarting the gettys is a problem
they should be sleeping 100% of the time
f
So why is the guest-agent constantly stopping for him?
Copy code

c
@quick-keyboard-83126 are you constantly seeing also
Copy code
Mar  2 17:41:40 alpine <http://daemon.info|daemon.info> supervise-daemon[6156]: Child command line: /usr/local/bin/rancher-desktop-guestagent -kubernetes=false -iptables=false -debug
Mar  2 17:41:40 alpine daemon.warn supervise-daemon[3443]: /usr/local/bin/rancher-desktop-guestagent, pid 6156, exited with return code 0
? I thought these were just from a restart or something?
q
slow moving train wreck?
Untitled
f
Yes, they were also coming every 10 seconds. I thought that was the issue we are talking about here. The getty one messages are just noise
q
imo they're all bugs
there's no reason any of these things should be restarting or thinking periodically if no one is doing anything to anything
And that's a description of the host:
Copy code
jsoref@jsoref-mbp ~ % docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES
f
I found https://gitlab.alpinelinux.org/alpine/aports/-/issues/11599 about the getty issue, but I don't understand why it only happens on aarch64 then.
c
yeah, he tried that already
q
yeah, we all found that
f
Can you file a Github issue for this, maybe we can just disable the serial console in the image. I just don't want to break the ability to use 
socat
on 
serial.sock
to connect to the VM when 
ssh
is broken. But maybe we no longer need this (and it doesn't work with vz anyways)
q
yeah, i guess i can, i'm currently baby-sitting some cleanup elsewhere
f
But this doesn't explain the guest-agent problem, which is what I'm more concerned about
Anyways, time for another meeting...
Hmm, I suspect we will also lose 
serial.log
if we disable the tty, so not sure I want to do that
q
where's that file?
Copy code
lima-rancher-desktop:~# ls /var/log/
acpid.log                       dmesg                           lima-init.log                   openresty                       wtmp
cloud-init-output.log           docker.log                      messages                        rancher-desktop-guestagent.log
f
It is on the host; symlinked from 
~/Library/Logs/rancher-desktop/lima.serial.log
q
that can't possibly be from tty stuff
it includes UEFI
f
Yeah, doesn't look like it:
Copy code
-chardev socket,id=char-serial,path=/Users/jan/Library/Application Support/rancher-desktop/lima/0/serial.sock,server=on,wait=off,logfile=/Users/jan/Library/Application Support/rancher-desktop/lima/0/serial.log
Unfortunately we are wrong, When I build the ISO with this change, then 
serial.log
is empty:
Copy code
--- mkimg.lima.sh
+++ mkimg.lima.sh
@@ -10,8 +10,7 @@ profile_lima() {
        initfs_cmdline="modules=loop,squashfs,sd-mod,usb-storage"

        apks="$apks openssh-server-pam"
         if [ "${LIMA_INSTALL_CA_CERTIFICATES}" == "true" ]; then
So not going to make that change
q
does it really lose the uefi bits too?
f
Copy code
$ ls -l ~/.lima/rd/serial.log
-rw-r--r--  1 jan  staff  0  2 Mar 11:39 /Users/jan/.lima/rd/serial.log
q
that makes absolutely no sense
ok, but can you just drop the 
console=ttyS0,...
part and leave 
syslinux_serial=....
?
f
I can try, but after that I will have to move on (for now). My bigger issue is that Alpine 3.17 doesn't work on aarch64 with Apple's virtualization framework. And I'm not dealing with it either, except by rolling back to 3.16 (for now).
Now I get this:
Copy code
$ cat ~/.lima/rd/serial.log

ISOLINUX 6.04 6.04-pre1  Copyright (C) 1994-2015 H. Peter Anvin et al
boot:
Loading /boot/vmlinuz-virt... ok
Loading /boot/initramfs-virt...ok
So, not going to disable the serial console for now.
Did you have a way to stop the restarts later? Can you just comment it out in 
/etc/inittab
and it will stop?
q
tried, didn't work
f
😞
q
yep
doesn't make any sense, but, also didn't work
f
Ok, will have to wait for later; it really is just an annoyance right now though, it doesn't actually break anything?
q
yeah, it's just an annoyance.... i mean, to some extent every stupid process that's actively waking up my poor computer hurts its battery
i'm only looking at logs because i'm trying to figure out how to convince docker to talk to a different internet egress and that's been all sorts of fail
f
Yeah, I know, there is a lot of polling going on that we should try to rein in
👍 1
q
if i wasn't trying (and failing) to get docker to do this, i wouldn't have looked under the hood
f
got it
At least we have a Github issue now
