I’ve built a virtual museum with nearly every operating system you can think of(virtualosmuseum.org)

Pardon a simple question - this implies nested virtualization, or is the second step emulation?

The download is a Linux VM, gotcha.

Are other OS-s nested virtual machines inside that Linux VM, or emulators (in which case, holly mackerel, that is even more impressive :O... and also why??).

Readme seems to imply it's emulators, but it also uses the words "virtual/virtualization" or "VM images" liberally sprinkled.

I imagine the author's using OpenSIMH (https://opensimh.org) or something similar, so it'd be an emulated CPU running the userlands.

I have a container that runs a 4.3 BSD userland using opensimh; it's not super hard to set up, just takes a bit of patience and willingness to learn how opensimh works.

Several different SIMH forks are included, along with a lot of other emulators; there are well over 150 different emulators, with some having multiple versions and variants present to handle things like regressions related to specific OSes.

Nested virtualization for certain x86 OSes running in QEMU is supported, although you will have to enable it manually (VirtualBox has a checkbox for this in its settings). For VMs that support it, the QEMU launch scripts will automatically use KVM if available and fall back to TCG if nested virtualization isn't enabled.

Thx! You got a new, albeit small scale, patreon - this is awesome :)

Could really do with a torrent. 120GB at 3MB/sec...

If my download ever finishes i'll spin up a torrent.

So far on retry/resume #12, 97.3/120GB done (i am live updating this comment as long as i can)

Yeah I tried to tell him that the other day… I think he under estimated the popularity that this would have on HN and thought that cloudflare would be able to handle it

I also could not find TempleOS, which obviously was the first thing i searched for - anyway great collection and page's look & feel. Thank you for creating & sharing.

This is a great resource. Did you run into any weird emulation quirks with the older OSes? I imagine getting some of them to boot wasn't straightforward.
andreww591 5 hours ago|
Yeah, they're very common. Some emulators like QEMU and MAME have many different versions included in order to deal with regressions.

This is wonderful. I'm looking forward to looking thru it properly. My earliest "real computer" memories are VAX/VMS and SunTools...

I wrote a SunTools front end to a simulation hosted on a VAX. I don't recall how we moved the data back and forth (serial port of some kind, most likely). I also can't recall "what it was like using SunTools and SunView". Just that, whatever or however it was done, I managed to get it to work. :)

Searched, but could not find OS/9.

[edit] No, found it!

andreww591 4 hours ago||
Multiple versions and variants of OS-9 are included. There are images for NitrOS-9 on CoCo and Dragon, several ports of OS-9/6809, OS-9/68K 2.4 for X68000, and OS-9000/x86 6.1.
