And is KVM available in Android without “rooting” ?
I don’t know. Why don’t you just try? qemu-system-arm64 --enable-kvm ..., IIRC.
Can you suggest anyone/anywhere to post the suggestion that Xubuntu have a “light” installation option (as per Ubuntu Server) because it is supposed to be a “light” distribution?

Yes, I am currently struggling with this, with help on Reddit, and it seems the Termux version of qemu-system-aarch64 has some odd configurations, not documented because its -h help is simply copied from qemu-system-x86_64!
Xubuntu has a Minimal Install iso
Xubuntu Minimal
Is this what you mean?
Ah yes, indeed!
Perhaps, if it can’t be combined into the boot options of the desktop install ISO, that separate download could be offered immediately alongside it?
Well, give it (minimal xubuntu 26.04 iso) a go
You may be pleasantly surprised or end up with steam coming out of your ears… 
Just so you know, there is no ARM64 ISO of Xubuntu. I think the best approach is with the server ARM64 installer. Just install the minimal, perhaps even the minimized task/metapackage and then sudo apt install xubuntu-desktop-minimal. If you want the full Desktop experience, you’ll also need to install the App Center: sudo snap install snap-store
I really think you should go for the native architecture, even if KVM doesn’t work, because the TCG shouldn’t acutually have to do too much, as opposed to building CISC instructions from a RISC instruction set in the AMD64 case.
