This might be a dumb question, So my Toshiba satellite m100-221’s CPU supposedly has CPU support for virtualization, but there is no BIOS update file anywhere so is there a way to run OpenWrt and Debian as my docker host without virtualization or some type of virtualization that doesn’t need CPU support and doesn’t run terribly, I found that I can use OpenWrt as my docker host https://openwrt.org/docs/guide-user/virtualization/docker_host?s[]=go&s[]=option has anyone tried that does it work nicely?
edit: I tried openwrt as my docker host it works fine enough
Docker is not virtualisation, although it’s a common misconception.
A better way to think of it is a security wrapper around untrusted processes.
You can prove this for yourself by looking at all the processes running in a Docker host while one or more containers are running, you’ll see all the processes listed.
In other words, you don’t need a CPU capable of virtualisation to run Docker.
Just the heads up, that cpu is ancient. Its performance is comparable to an Rpi 4, but that old cpu consumes 30W+ while a full rpi maxes around 6-7 W. Rpi 5 is around 4-5 times more powerful with third power.
So it’s good if you just tinkering with old hardware for fun, but you can buy far more powerful modern hardware for only several dollars if you look at the second hand market.
Also I remember, I dealt with Toshibas from that era, they were quite locked down, e.g. you couldn’t install upstream nvidia drivers on them only the outdated ones signed by Toshiba. So it’s not unexpected that some options like that are missing in bios settings.
Virtualization cpu support only help with performance. You can run VMs without it…
You could even run a VM with full software emulation somehow…
How big would the performance hit be for that? I want to run quite some apps
Wait, docker doesn’t require any hardware virtualization that’s only for VMs…
I would strongly recommend that you get some newer hardware. That thing isn’t going to perform well plus you will likely run into hardware failures due to age.
It doesn’t even have gigabit networking
I don’t know why you want a BIOS update.
If you’re wanting VT-x support, looks like it’s present.

VT-x
https://superuser.com/questions/1584771/what-is-difference-between-vmx-and-vt-x
The CPU flag for VT-x capability is “vmx”; in Linux, this can be checked via /proc/cpuinfo
because there is no option to enable it in the bios and proxmox says its not enabled so i can’t run kvm
