FlightAware ADS-B Flight Tracking
166

OK, I think I can declare this experiment a success (running piaware running on Ubuntu 16 on VMware Player 6 on WIndows 10 (32-bit) on Asus Eee PC netbook circa 2010 with Atom CPU). Setting the VM’s memory size to the minimum (512 MB) and not running any other apps on the host laptop seems to help.

I plan to get piaware / dump1090-fa running on a RPi, as it would consume much less power than the Asus netbook. But this was an interesting experiment, and I learned a lot in the process. Thanks to all of you for your kind help and information throughout this process.

This experiment showed that it is perfectly reasonable to run piaware / dump1090-fa in a VM. The VM had 512MB memory running Ubuntu Server version 16 32-bit Linux on VMware Player version 6. This was run on a circa 2010 Asus Eee PC netbook w/ a single-core Intel Atom N450 CPU on Windows 10 32-bit w/ 2 GB memory.

The crowning achievement of this thread was 100% due to @abcd567. I am merely reproducing @abcd567’s results and reporting them here. The recipe calls for starting with Raspberry Pi Desktop, and then following @abcd567’s excellent instructions for building and installing dump1090 and piaware (which should replace the READMEs in github.com:flightaware/{dump1090,piaware_builder}). Those precise instructions enabled me to do correct builds for the first time. I am now running dump1090 and piaware in a RPi Desktop VM with 512MB memory running on VMware Player version 6 (free for non-commercial use) on Windows 10 32-bit on an circa 2010 Asus Eee PC model 1005PEB with an Intel Atom CPU and 2GB memory. Note that if your Windows laptop can run it, you would be much better off using VMware Workstation Player version 15 (free for non-commercial use). The dongle is an early model NooElec R820T (Realtek Semiconductor Corp. RTL2838 DVB-T) with the stock indoor antenna near a window. I understand that I would have much better results if I ran dump1090/piaware on a RPi with a better dongle and an outdoor antenna. This was mainly an experiment to determine whether dump1090/piaware can run in a VM on an old Windows laptop, and the answer is definitely YES.

So far, I’ve seen only 7 ‘unstable clock’ periods in about a day and a half:

Are you sure the os on first pi4 was 64-bit? Seems you used 32-bit os. Please give these 2 commamf on first Pi and post output. It will reveal weather you have 32-bit or 64-bit on first Pi4.

uname -a

First Pi = armv7l = 32-bit

Second Pi = aarch64 = 64 bit

On first Pi4 you have instslled 32-bit OS, while on 2nd one you indtalled 64-bit version.
