I recommend not using more than 1 CPU in the VBox

configuration.

Later versions of VBox work a little better than older ones, but it
looks like the support is similar to HYPERTHREADING, and
HYPERTHREADING is not, at all, friendly to OS/2. Using it will
probably result in hangs, after a while (usually less than 10
minutes).

which version on Vbox? here there is the latest 6.0.14 r133895

That one seems to work better than earlier versions, but I still
recommend using only one CPU in VBox. You will probably see
hangs, if you try more than one. From what I see, the second CPU
doesn't make much difference anyway.

which version of host OS? here windows server 2019 standard

edition

64bit

I use win 10 PRO 64 bit.

Windows Server is more stable/reliable for virtualization in general
maybe under Win Server there are no issues with multi-cores

my AOS VM is running since this morning i'm doing everything
and it seems rock solid stable

massimo

i had my AOS 503 installation, is very feature-poor
no winos2, no usb, no audio, no aspi, no cups, no hpfs, no fat3, no iso-fs,
all dos virtual memory drivers are disabled etc.. etc..

maybe as desktop use it is not so much stable
i use it as a server

eg. i've seen usb drivers doing weird (hang) stuff..
i've really commented a great number of entries in config.sys

this VM have to runs only 3 apps, moylan ftp server, apache and php
and rsync for bkups
stop
