Booting Micro Core in Amazon EC2
« on: September 18, 2012, 07:23:05 AM »
I just wanted to say that I am very close in getting Micro Core booting in EC2. However, it abruptly stops booting with no error messages after setting the language to C. I'm simply uploading a loopback image of TCL into S3 and deploying it from there. Inside the loopback file I have /boot which contains core64.gz, vmlinuz64, and grub/menu.lst. It contains etc/fstab file, a opt/* directory with the backup files listed in .filetool.lst, a tce/ with all of the packages I want installed and proc/ directory. I'm using a PV-GRUB 1.03 hd0 partitionless Amazon kernel id which will boot my image, so my grub menu.lst looks like:

Code: [Select]
default 0
timeout 0
 
title MicroCore
root (hd0)
kernel /boot/vmlinuz64 noautologin root=/ tce=/ opt=/ home=/ noswap console=hvc0
initrd /boot/core64.gz

The following is the entire system boot log on EC2:

As you can see it just stops after setting the language with no error messages. I'm not sure why it would be stopping. Could this have anything to do with TCL not finding a filesystem?

None of those are valid.

I don't know quite what you are trying to do, but it does not look like TC is the distro to do it.

I'm just trying to boot a TCL instance on EC2. Why I'm trying to do this is irrelevant. Since I'm documenting everything as I go, hopefully if I have success I can post it so others can do it easily without so much hassle.

Regarding the kernel options, when I use:

root=sda1 tce=sda1 opt=sda1 home=sda1
OR
root=xvda1 tce=xvda1 opt=xvda1 home=xvda1
OR
root=hd0 tce=hd0 opt=hd0 home=hd0

It displays the same boot log as above.

root is not a valid tc boot option.

Hi teagy

That comes from tc-config. After that, it looks for the RTC, however, the boot log shows:
Code: [Select]
rtc_cmos rtc_cmos: rtc core: registered rtc_cmos as rtc0
rtc_cmos: probe of rtc_cmos failed with error -38
and:
Code: [Select]
drivers/rtc/hctosys.c: unable to open rtc device (rtc0)From tc-config:
Code: [Select]
[ -n "$LANGUAGE" ] || LANGUAGE="C"
echo -n "${GREEN}Setting Language to ${MAGENTA}$LANGUAGE"
echo "LANG=$LANGUAGE" > /etc/sysconfig/language
echo "${GREEN} Done.${NORMAL}"

if [ -n "$TZ" ]; then
echo -n "${GREEN}Setting Timezone to ${MAGENTA}$TZ"
export TZ && echo "TZ=$TZ" > /etc/sysconfig/timezone
echo "${GREEN} Done.${NORMAL}"
fi

while [ ! -e /dev/rtc ]; do usleep 50000; done
if [ -n "$NOUTC" ]; then
hwclock -l -s &
else
hwclock -u -s &
fi
If I'm reading it correctly,  while [ ! -e /dev/rtc ]; do usleep 50000; done  will wait forever if it does not find the RTC.

I don't think this belongs under TCL Base, sounds more like Virtual Machines or Off Topic. Moving to VMs.

If you use 4.6.1. I have added a new boot code of nortc

Thanks a lot Roberts for that convenient addition. Hopefully removing the rtc device check won't negatively impact the system. I was using 4.6, so I'm going to update Core, try this out and see what happens.

Success! Ok, I've got Tiny Core booting in Amazon EC2. Once I've finished all of my documentation, I'll come back and post it. To be honest, I wanted to try TCL out on EC2 because of how fast it could boot which significantly improves the boot time on EC2 vs the Ubuntu 25-30 sec boot times from the stock images.

I'd be very interested in reading your conclusions as I'd like to do the same on GreenQloud, an Icelandic EC2 clone powered by renewable energy.

Thanks in advance!
