CPU: Pentium Dual CPU E2200 @ 2.20GHz
This is a 2007 CPU and indeed it does not support VT.
Right, but age alone is not the main problem, it's the CPU/BIOS combo.
Some CPUs do support intel vt or amd-v, but the BIOS gets in the way.
Not seldomly, that totally confuses the VM software.
In older versions of VMware, VirtualBox, MS Virtual PC that Hardware-virtualization was optional..
In case of VirtualBox, the 2.x/3.x series are compatible with AMD K9 and comparable intel processors.
The early 4.x series may also be fine with such older processors..
I've run VBX 4.1.14 (r77440) on a Mac OS X compatible, with Core2Duo processor, I think.
VirtualBox v5 is said to be incompatible with lots of stuff currently (ReactOS ezc), so better avoid that.
Anyway, hardware-virtualization is not always best for compatibility/stability.
From what I remember when using Virtual PC 2007/AMD-V:
Windows 3.11 needed it for Win32s
Windows 98SE got totally unstable
OS/2 also was affected.Not sure how, though.
In DOS VMs, it sometimes was helpful, sometimes it made applications crash.
Using EMM386 helped a lot, because it ran in V86. I assume, this avoided using Virtual PC's internal Real-Mode handling mechanism (emulation core? hacky virtualization?).
